Abstract: Applying the microcontroller and the ball screw pair, a transient throttle control system for engine research is developed. The general scheme, hardware composition and software design of the transient throttle control system are introduced. The system has the characteristics of high precision and favorable visual interface. The experiment results and the application show that the system’s angular velocity and angular acceleration of the
throttle’s rotation are in high precision and meet the requirements of the actual application.
