hybrid control is designed to ensure both the system performance and the robust stability. The H

norm of the sensitive function from the parameter perturbation of the system circuit to the control input is taken as the evaluating index of the robustness

and the H

norm of the transfer function from the external disturbance to the angular velocity of the motor as the index of linear quadratic Gaussian(LQG). The simulated and experimental results show that the hybrid control is endowed with good control performance to attenuate the parameter perturbation

nonlinear and the external disturbance. Furthermore the electric vehicle recycles more kinetic energy during regenerative braking with the proposed control s
