First, the dynamic equilibrium point is obtained from the working property of the induction motor; and then, a proper state feedback is chosen to build the dynamic model of the system. The Hamilton controller for the dynamic equilibrium point is designed based on the energy-dissipative nature. This method ensures the global stability of the system. Simulation validates the efficiency of the proposed control scheme. Key words: electric vehi
