Study on the Improved Fuzzy Control Strategy of Engine Throttle Position Control System

The position of the engine throttle is driver´s reflection to the vehicle power and the request of the vehicle speed. In the technical vehicle energy-saving automatic shifting gears control system, it is requested that the engine throttle position control system must have the precise position response, the higher speed of response, and the stronger stability and robust. The process of engine throttle position control has the characteristic of non-linearity. Using normal control method can not get better control effect. According to fuzzy control theory, do the relative transformations to the input signal and the calculus of interpolation to the fuzzy control table, the improved fuzzy control algorithm is formed. The result of the test indicated that the system of using the improved fuzzy control strategy has the better control effect and the characteristic of the high speed of response, the smaller static error and the better stability.
