ジャーナル フリーFitts' law is a useful means to accurately model human movement time, and has been widely adopted in human factors and human-computer interaction. As Fitts' performance model is one-dimensional, it may not be proper as a performance predictor in a two-dimensional pointing task. The purpose of this study is to suggest new definitions of target size and target distance in the performance model which predicts the pointing time of two-dimensional pointing task in computing systems. Target was a rectangle. Experimental factors were target size, aspect ratio of target, target distance, and approach direction to the target. Pointing time, coordinate of pointer (mouse pointer), and trajectory length were measured. Two-dimensional effective target width was used in the five definition of target size (W', min(W, H), W+H, √W·H, W·H; W is target width, H is target height). Direct distance and trajectory length were adopted as target distance. From the result of contribution of performance model, it was clarified that applying W' as target size and trajectory length as target distance was more effective than a traditional method.抄録全体を表示PDF形式でダウンロード (2307K) -

ジャーナル フリーThis paper presents a new design approach to robust stabilizing controller for nonlinear systems with time-delay related uncertainty. The key idea of the design approach is to dominate the derivative of Lyapunov-Razumikhin function whenever the Razumikhin condition holds. It is shown that by exploiting the proposed domination design approach, a solution of robust stabilization problem can be derived for the nonlinear systems that has cascaded form and triangular structure with bounded time delay related uncertainty. Finally, a numerical example is given to demonstrate the effectiveness of the proposed approach.抄録全体を表示PDF形式でダウンロード (1925K) -

ジャーナル フリーSince most processes have nonlinearities, controller design schemes to deal with such systems are required. On the other hand, PID controllers have been widely used for process systems. Therefore, in this paper, a new design scheme of PID controllers based on a memory based modeling (MB modeling) is proposed for nonlinear systems. According to the MB modeling method, some local models are automatically generated based on input/output data pairs of the controlled object stored in the data-base. The proposed scheme generates PID parameters using stored input/output data in the data-base. This scheme can adjust the PID parameters in an on-line manner even if reference signals are changed, and/or system parameters are changed. Finally, the effectiveness of the newly proposed control scheme is numerically evaluated on some simulation examples.抄録全体を表示PDF形式でダウンロード (1205K) -

ジャーナル フリーThis paper discusses an on-line approach to Model Predictive Control (MPC) of input constrained linear systems. First, it is shown that an example of MPC with one-side input constraints is reduced into the Linear Complementarity (LC) problem with an M-matrix, which can be more efficiently solved by the existing special algorithm than the other general algorithms such as the Lemke method. However, in the case of both-side input constraints, which is more practical from the control engineering points of view, it can not be reduced into the LC problem with an M-matrix. Thus, next, a new algorithm for the case of both-side input constraints is proposed in this paper. The effectiveness of the proposed algorithm is shown by a numerical simulation.抄録全体を表示PDF形式でダウンロード (2041K) -

ジャーナル フリーThis paper is concerned with sampled-data H∞ control of linear parabolic systems with unbounded output operators. It is assumed that the input and output spaces are finite-dimensional. For the infinite-dimensional continuous-time system with an ideal sampler and a zero-order hold, the aim is to construct a finite-dimensional discrete-time stabilizing controller that makes the L2-induced norm of the feedback sampled-data system less than a given positive number δ. For that purpose, the infinite-dimensional continuous-time system is formulated as an infinite-dimensional discrete-time system by using a lifting technique. Based on a reduced-order model with a finite-dimensional state space for the infinite-dimensional discrete-time system, a finite-dimensional controller containing a residual mode filter is designed to provide the desirable performance.抄録全体を表示PDF形式でダウンロード (1520K) -

ジャーナル フリーThis paper studies the synchronization of network coupled systems consisting of many identical dynamic subsystems as well as network coupling with interaction time-delay. Based on graph theory and Lyapunov stability theory, the paper gives two sufficient conditions for the total system synchronization with respect to the graph structures of network coupling interaction, one is delay-independent and the other is the delay-dependent. These two conditions are compared with Wu's research, which was established without taking interaction time-delays into account. Simulations with two examples show the influences of the interaction timedelay as well as graph structures on the overall synchronization of subsystems.抄録全体を表示PDF形式でダウンロード (2150K) -

ジャーナル フリーIn this report, the tracking control of n dimensional rigid body without angular velocity measurements is considered. Combining the angular velocity observer proposed in the previous paper, it is possible to design output feedback with the so-called reduction property in the sense that the proposed control law reduces to the one that achieves set-point regulation when the desired trajectory is stationary.抄録全体を表示PDF形式でダウンロード (1201K) -

ジャーナル フリーRecently a new approach is required for a scheduling system which has flexibility against alteration of problem condition. This paper deals with a multiobjective rescheduling problem in a job shop for alteration of due date. The objectives of this problem are to minimize both the total tardiness and the degree of the change of schedule. The design of genetic algorithm (GA) is proposed for obtaining the Pareto optimal solutions. The initial solutions in the proposed algorithm are generated from the non-dominated solutions in the population obtained for the problem before the alteration. The selection operation is designed so as to choose two solutions from two parents and four offspring generated by means of the crossover operation and the mutation operation. In this operation we introduce a procedure in such a way that not only non-dominated solutions but also solutions to move the population in one direction inferentially are selected. It is confirmed from the computational result that the proposed GA outperforms a local search method and the strength Pareto evolutionary algorithm.抄録全体を表示PDF形式でダウンロード (2189K) -

ジャーナル フリーMutual entrainment of rhythm is widely observed in the music performance between humans. However, one-sided action is dominant in the performance between human and musical machine. Thus, in this research, we try to realize human-like ensemble system by using mutual entrainment between human and machine, and constructed it by using coupled non-linear phase oscillator model. We also evaluated the system from objective side by using phase difference between human and machine, and from subjective side by using questionnaire to the performer. As the results, our system was estimated as more human-like than previous system, and the effectiveness of our model and the importance of mutual entrainment was shown.抄録全体を表示PDF形式でダウンロード (5482K) -

ジャーナル フリーThis paper examines the combination control of the manual operation and the autonomous motion on tele-operation of mobile robot. The autonomous motion that is suitable for the situation when the robot passes through a passage with bends is examined to improve the maneuverability with using a computer simulation. The situation that the manually operated robot contacts with the sidewall of a passage is investigated with the experiments. It is pointed out that the contact tends to occur around the entrance and exit of bends: a robot tends to contact with the inside near the entrance of the bend and the outside around the exit of the bend. The situation that the operator uses the autonomous motion of the mobile robot under the combination control is also investigated with the experiments. The operator tends to use the autonomous following (FL) near the entrance, and the autonomous revolution (RV) is effective to make the robot return to the center of the passage around the exit. From these situation analyses the selective-revolution/following (S-R/F) is developed in which the situation is estimated based on the direction of the manual operation of the operator and the direction of the obstacle from the robot then the autonomous revolution or the autonomous following is selected and applied according to the estimated situation. The new technique is equipped with the simulation system and it is confirmed that the autonomous revolution against the operator's intention is not applied based on the situation, so the maneuverability can be improved.抄録全体を表示PDF形式でダウンロード (3338K) -

ジャーナル フリーThis paper presents the concept and design of automated solution (called AOPS), which is proposed to synthesize operating procedures of chemical batch plants. The proposed solution is used to synthesize master recipe and generate the corresponding control recipe on the basis of recipe formal definition language (called RFDL). RFDL enabled smooth and systematic mapping between operating procedures and domain knowledge. Integrated user interface is designed to capture plant design model and the associated domain knowledge, and used to visualize and validate the generated control recipe as mapped to plant topology. A case study of 2-stage polymerization batch plant is used to illustrate the proposed solution.抄録全体を表示PDF形式でダウンロード (4381K) -
