Focus on the basis of the mathematical model for the electronic throttle, a sliding mode control strategy based on the nonlinear terminal sliding surface is designed on the basis of the nonlinear characteristics of the electronic throttle system which used in hybrid electric vehicle and the disturbance in the control system. At the same time, in order to realize the electronic throttle of the hybrid power vehicle under the complicated driving condition. The non measurable variable and uncertain disturbance of the gate control system are accurately estimated. The nonlinear expansion state observer is designed. The experimental verification of the angle following of the electronic throttle under three different operating conditions is tested. The experiment proves that dual loop sliding mode control strategy is used to improve the convergence speed of the valve system and the phenomenon of no-overshoot. It meets the target that hybrid electronic vehicle′s electronic throttle has high precision angle following performance.
