Position control of ball and plate system based on switching mechanism

According to the dynamic characteristics of the ball and plate system, the mathematical model and the corresponding simplified model are derived, and the analysis of the applications of different types of PID controllers is given. Based on the result of the analysis about different controllers, the controller by using switching mechanism is proposed for position control of the ball and plate system. Finally, all these algorithms are tested on the GPB2001 ball and plate system experimental platform. The studying by experiment shows that the effect of switching control is better than conventional PID control.
