摘要：AbstractPrecise electronic throttle control is a basic problem of engine control. This paper identifies the model parameters based on input PWM, throttle output angle and angular velocity. But the angular velocity can not be measured directly. Therefore, the kalman filter is applied to calculate the angular velocity. A hybrid optimization algorithm is used to search the parameters of throttle model which minimizes the errors between model and real throttle output angle and angular velocity. The controller is designed based on identified parameters and triple-step nonlinear control design. Experimental results indicate the effectiveness of the identified parameters and the controller.
