The sliding mode control is a robust control design method, but chatterings sometimes occur in applications. This paper used a fuzzy-sliding mode control to improve the stability of automotive engine speed. Firstly,the fuzzy control vectors are introduced to the total control vectors. Secondly, the design strategy for the fuzzy control vectors was presented.Finally, simulations were done with MATLAB.The simulation results show that engine speed chattering swing is reduced to 10% and the chattering frequency is reduced to 15%.
