H/sub /spl infin// sliding mode tracking control for Chua's circuit

In this work, H/sub /spl infin// 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/sub /spl infin// 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.
