Application of switching control to test turntable

The robust stabilization of switched systems with nonlinear disturbance and its application are studied, and the sliding mode control theory is applied to the controller synthesis. The reduced-order sliding mode dynamics and a sufficient condition of its stability are given by introduce a linear transformation. Moreover, the switching law is chosen and a sliding mode control law is synthesized based on the new coordinates states. The designed sliding mode control law is proved to guarantee the reachability of the pre-defined sliding surface, and thus the sliding mode dynamics is resulted. The new method is applied to high precision test table. Simulation results verified the effectiveness of the proposed method.
