Syntheses of Discrete Optimal Regulator with Disturbance Inputs

This paper presents two methods for synthesizing discrete optimal regulator with disturbance inputs. Under step disturbances, the closed loop control systems synthesized by these methods have X(k)=0 and ▽X(k)=0 when k→∞, where X(k) is the state vector of the control system and symbol “▽” represents the difference operator.
