Singular LQ suboptimal control problem with disturbance rejection for descriptor systems

摘要

This paper deals with singular linear quadratic (LQ) suboptimal control problem with disturbance rejection for descriptor systems. Under some conditions, a suboptimal control-state pair can be found such that the performance of the closed-loop system is within some range; the suboptimal control can be synthesized as state feedback and the state trajectory of the closed-loop system is uniquely determined by disturbance and initial state.
