The classical PID control algorithm is often used in the traditional mechanical gripper controller.Although the implementation of PID control is simple,it is difficult to ensure the optimal motion of the gripper.In this paper,based on the minimum variance control theory,the controller gain is obtained by solving the Diophantine equation,and the minimum fluctuation variance of the gripper is achieved.Compared with the traditional PID algorithm,the simulation results show that MVC algorithm controller can effectively improve the dynamic performance with strong signal tracking ability.
