Engineering Method of Optimization of Digital Control Systems

摘要

For optimization of digital control systems we proposed integral performance criterion with minimization of control influence. Unimodality of performance criterion is confirmed numerically. For single-circuit control system we ascertained numerically functional dependence of optimal parameters of digital controller on dynamical properties of controlled object. Design formulae differ from existing ones by simple structure, high accuracy of determination of optimal parameters of controller and wider range of applicability. Usage of the proposed method does not demand knowledge of discrete system theory, which is significant for engineering service personnel of enterprises.
