Position control for filter rod splint based on fuzzy-PID

According to the precision position control requirements of the filter rod splint in the filter rod packing machine system, in this paper, the drive of filter rod plate movement of permanent magnet synchronous motor (PMSM) as the controlled object, on the basis of the mathematical model of PMSM, the three closed loop control system of current loop, speed loop and position loop are determined. In which the current loop and speed loop are used as the inner loop by using the classical PID control. Since the outer position loop related to the stability and precision position control of system, so it is the key to the servo control system design, using the fuzzy-PID controller to achieve. Simulation results show that: the method used can well meet the accuracy requirements of the filter rod splint position control, compared with the traditional PID control strategy, the control indicators may be improved.
