Stop and Go Cruise Control on Series Hybrid Electric Vehicle

To deal with the model uncertainty and external disturbance which may exist in series hybrid electric vehicle BJUT-SHEV's stop and go condition,an adaptive sliding mode control method based on nonlinear disturbance observer theory is proposed.In the method the nonlinear disturbance observer is introduced to estimate system uncertainty,and the estimate value is used to compensate control outputs which to improve sliding mode controller's performance and robustness.In addition,for controller output chattering case an adaptive law is designed,under the adaptive law the sliding mode controller's switching gain can be adjusted automatically.The Lyapunov method is applied to prove the stability of the control method.Finally,the simulation results of an example are investigated to show the feasibility and effectiveness of the proposed approach.
