The Application of Fuzzy PID Control in the Control System of Transplanting Manipulator
Aiming at the problem of low output precision of transplanting manipulator due to the interference of external factors,a control method of transplanting manipulator based on Fuzzy PID control strategy is proposed.Firstly,based on the control sys-tem model of transplanting manipulator,a new control method of transplanting manipulator is proposed by combining fuzzy con-trol theory with PID control theory.The control process of transplanting manipulator is simulated and analyzed by Matlab/Simu-link software,and the control effect of conventional PID control and fuzzy PID control on transplanting manipulator control sys-tem is compared.The results show that by adjusting the PID parameters,the output step response time of the proposed control method is increased by 56%compared with the traditional PID control.The fuzzy PID control overcomes the shortcomings of non-linearity and low control precision of the manipulator control system,and improves the stability of the control system.
