Based on the ergodicity and state PI regulator theory of chaotic systems, a new stabilization and set point tracking method for unstable equilibrium points of chaotic systems is proposed. Lyapunov matrix inequalities for controller parameter design are given. For the piecewise linear chaos In the system, such as Chua’s circuit, the controller parameters can be designed through the pole placement technique in the control theory. The proposed method is robust to system parameter variations and can eliminate external setpoint disturbances. This method is applied to Chua’s chaos circuit The stabilization of the unstable equilibrium has yielded satisfactory results.
