| Abstract: | This paper introduces a VGT control system which is equipped with a step motor as the actuator. In order to effectively control the nozzle area so as to improve engine performance in both steady and transient states, a control scheme is worked out by combining predictive function and the super charged pressure feedback method. In the testing the system, satisfactory results are obtained. This system is proved to be simple and practical. |
