ABSTRACT:
A central processing unit (CPU) receives moving distance data from a main CPU to compute the objective position data corresponding to the position to which an object is to be moved. The CPU computes a first deviation value between the objectives position data and the moved distance data of an object to be controlled every sampling time, reads the actual position data and the moved distance data of an object to be controlled every sampling time, reads the actual position data of a motor and computes a second deviation value by subtracting the motor position data previous to a first sampling time from the actual position data of the motor. The CPU also computes a third deviation value by subtracting the motor position data previous to a second sampling time from the motor position data previous to the first sampling time, and subtracts or adds a fourth deviation value, calculated by subtracting the third deviation value from the second deviation value, from or to the motor position data previous to the first sampling time to control the position of the robot system.
