H∞ sliding mode tracking control for Chua´s circuit

In this work, H_∞ sliding mode control is applied to enhance the robust tracking of Chua´s circuit systems. Chua´s circuit is transformed into standard control canonical form firstly. Furthermore, the error dynamics can be formulated from the master and slave Chua´s circuits. In so doing, the tracking problem can be viewed as regular one. Then, H_∞ sliding mode controller is presented to achieve the robust stability under the effect of external disturbance. The simulation results can demonstrate the feasibility of this approach.
