Estimation of Parameter Sensitivity of Linear Control Systems

概要

System-parameters of linear control system generally have some variations about the assumed -values because of an inaccuracy of their measurement and time-functional variations in operation. If these variations in the assumed values are regarded as a kind of previously unknown disturbance, it should be considered that their undesirable effects on the estimated value of the system are to be minimized. In this paper, such control systems are investigated and the effects of the systemparameter variations, which are independent of time or slowly varying, are analysed. Not only, deduced from the sensitivity function but also estimated from the variations of rms error, a method is suggested to minimize these undesirable effects. Also given are the experimental results of the synthesized system obtained by using analog computer.
