| Abstract: | A new composite nonlinear output feedback controller is proposed to track the time-varying reference inputs for multivariable linear systems with input saturation. Based on the original composite nonlinear feedback theory, werespectively developed the full-order and the reduced-order output feedback controllers. Both controllers consist of linear output feedback and nonlinear feedback, resulting in a closed-loop system with asymptotic stability in the invariant set inside the domain of attraction. Besides the guaranteed ability of tracking time-varying reference inputs, the systems have an excellent transient performance. Simulation results demonstrate the feasibility of the proposed controller. |
