    Electronic throttle actuator is a nonlinear device which has various factors, such as delay time of backlash, gear friction, throttle valve friction and stiffness of spring, can affect to the responsiveness of vehicle control. The major impact on electronic throttle control is the return spring load. It can cause both overshoot and undershoot behaviors while the electronic throttle operates. This paper presents an overshoot/undershoot suppressor technique by using anti-windup algorithm with simple architecture to eliminate unwanted behaviors. In the experiment, a conventional PID controller and the proposed fuzzy-PI controller are used, and also implemented into microcontroller chip. In addition, this paper reveals a single phase driver circuit for hardware setup. The experiment results show that the controllers with proposed overshoot suppressor can perform effectively. The controller performance is evaluated by using standard criteria: an integral of square error (ISE), an integral of absolute error (IAE), a maximum overshoot (OVM) and a maximum settling time (STM).
