ジャーナル フリーA method of designing the adaptive control system for the invariant closed-loop dominant conjugate complex poles has been developed by use of root-locus techniques. The method can be applied only to the controlled element containing one variable parameter varying with the surrounding conditions. However, it is also possible to apply it to the case where the transfer function of the controlled element is given in higher order rational function of s, whose coefficients change in large scale from the nominal values. Two subsidiary loops are required for the adaptation, one for phase adjustment, the other for gain adjustment. Each loop is composed of a nonlinear function generator incorporating the corresponding programming curve obtained graphically from root-locus and a servo which drives the adjustable controller.抄録全体を表示PDF形式でダウンロード (4562K) -

ジャーナル フリーPressure gauge movement can have a much better vibrating wear character with a suitable spring in place of movement link. When the mass of spring is large like a Bourdon tube, however, this improvement effect is small. The spring should be light and a few times as hard as Bourdon tube. Better wear character will be obtained with weaker spring. In this case, however, pressure gauge's normal frequency F0 drops too, resulting in reducing the range of use. It is pointed out once again that a lighter pointer has an advantage, because it raises F0. More care should be paid to the frequency Fc, it to be called “Critical Frequency”, F0, 3 F0, 5 F0, etc. It is not good to measure the dynamic pressure near the “Critical Frequency” of pressure gauge, because if it is done, resonance occurs, pointer is wildly vibrated and accordingly gear teeth are rapidly worn off. F0 is approximately 1000 cpm or less in general.抄録全体を表示PDF形式でダウンロード (1063K) -

ジャーナル フリーThe lithium chloride dew point thermometer has been noted as “Dew cell” since many years ago. Old type lithium chloride dew point thermometer has such weak points on practical use as it takes a long time from starting up to the time it has a stable pointing and it can not always start operation in the atmosphere of high temperature and high humidity. These weak points have been remarkably impro ved in the following ways:
1) Use as an electrode a kind of platinum wire of higher resistance.
2) Use a heat-treated glass fibre, into which aqueous solution of LiCl penetrates.抄録全体を表示PDF形式でダウンロード (6356K) -

ジャーナル フリーAlthough the recent development in numerical control of processes, especially in positioning control systems, is so remarkable, a few papers have been written on the design of such systems including quantizing elements.
By phase plane approach, this paper attempts to study the synthesis of an on-off positioning servomechanism, which is commanded by discretely valued step inputs and similarly quantized outputs. The response to inputamplitude and total gain is obtained in graph from normalized phase plane loci. The system is able to approach the time-optimal system for wide range of input amplitude by adjusting the total gain at zero velocity errorpoints. This method is proved from phase portrait to be superior to other conventional methods, suchas a slow down method, a method adjusting the gain atzero error points, etc.An illustrative example makes it clear.抄録全体を表示PDF形式でダウンロード (976K) -

ジャーナル フリーPrinciple of inverse transfer function compensation is very simple and yet useful as a design principle of control system. A self-adaptive system with a variable parameter PID controller based on this princi ple has been developed. In this system, parameters of PID controller are selected so that zeros of transfer function of the controller may cancel the poles of process approximate transfer function. Dynamics of the control system and stability of the adaptive loop have been discussed with several examples.抄録全体を表示PDF形式でダウンロード (1108K) -
