To enhance the performance of the tracking property
, this paper presents a novel control algorithm for a class
of linear dynamic stochastic systems with unmeasurable states,
where the performance enhancement loop is established based on
Kalman filter. Without changing the existing closed loop with the
PI controller, the compensative controller is designed to minimize
the variances of the tracking errors using the estimated states
and the propagation of state variances. Moreover, the stability
of the closed-loop systems has been analyzed in the mean-square
sense. A simulated example is included to show the effectiveness
of the presented control algorithm, where encouraging results
have been obtained.
