| Abstract: | In this paper, a new method for accurate position control of motor was introduced, in which PLC was used as controller, RS485 was used for motor driver port and high - speed - counter was used for feedback. The method for tuning parameters of position control algorithm and compensating system dead- zone was discussed also. In the end, a successful sample of this method used in reciprocating type bale plucker in textile mill was given. |
