摘要：
In this paper, output feedback control is investigated for a class of linear time-varying systems based on the ideas of controllable and observable canonical forms in the theory of linear time-invariant systems and high-gain observers in the theory of nonlinear systems. The state feedback controller, the state observer and the observer-based output feedback controller are respectively derived for linear time-varying systems by using time-varying transformations of state variables. It is further proved that the observer errors are asymptotically convergent to zero, and the state feedback controller and output feedback controller can demonstrate the asymptotic stability of the closed-loop system.
