A Design Method of Optimal Deadbeat Control System Considering the Time Delay Arising from the Computation

Abstract

This paper presents a new design method of optimal deadbeat control system considering the time delay arising from a computation. First, dynamic characteristic of the system is expressed by the step response. The deadbeat control signal which minimizes the quadratic cost function of the control signal and errors can be easily obtained by the matrix computation using sampled data of the system's responses. Then, parameters of compensators and feedback gain of the control system are easily determined from formulated matrix by using control signal having controlling delay. Finally, the effectiveness of the proposed method is confirmed by applying it to three different control systems.
