Research on adaptive control of crusher speed and position based on fuzzy PID control
In order to improve the control performance of the crusher,a fuzzy PID control based adaptive control algorithm for the speed and position of the crusher is proposed.The method takes the STM86 stepper motor control of the crusher as the re-search object,constructs a mathematical model of the crusher drive motor,and combines PID control and fuzzy control to design a fuzzy PID control algorithm to achieve adaptive control of the crusher.The results show that the overshoot of the fuzzy PID control algorithm for the speed and position control of the crusher is 4.20%and 0.13%,with adjustment times of 0.21 s and 0.02 s,and average following errors of 0.02 mm and 0.01 r/min,respectively.Compared with PID control,fuzzy sliding mode control,and fuzzy self anti-interference control algorithms,fuzzy PID control algorithm has lower overshoot,shorter adjustment time,and smaller average following error.From this,it can be concluded that this fuzzy PID control method can achieve better a-daptive control of the crusher and has certain practical application value.
