Study of a suboptimal control system

Abstract

A suboptimal controller based on linear quadratic optimal control theory is proposed for multivariable systems. The control law and the transfer function of the controller are derived. It is shown that the plant can be modelized by various dynamic models (state or recursive equations, pulse response sequences) and that the control law is unaffected by time delays in the plant. The influence of control law factors is investigated and illustrated by examples.Anglai
