An Integral Variable Structure Compensation Method for Electronic Throttle Control with Input Constraint

摘要：

Recently, the electronic throttle control (ETC) is popular in the automotive industry, it equipped with nonlinear characteristics because of its discontinuous nonlinear spring and model-parameter changes caused by external environmental variables. In this paper, we propose an integral variable structure compensation method by using sliding mode control (SMC) in order to improve the robustness of the ETC with input constraint and so as to realize higher intake-air efficiency for the engine practically. The electronic throttle model is introduced as a controlled object with parameter changes caused by body temperature variations regarded as the unstable factor. The input constraint can be compensated by the mutual effect of compensation gain and variable switching gain. The simulation results confirmed that by the proposed method, the excellent robustness of the electronic throttle is kept by the proposed method on the premise that 95％ of the requested throttle opening can be reached within 100 ms, even if the input voltage is considered, and model-parameter changes are loaded. In addition, the chattering is also eliminated greatly.
