ABSTRACT:
A control system which comprises a reduction gear unit containing gears, a motor being disposed on an input side of said reduction gear unit, a sensor for detecting a turning angle of said motor, and control means for inputting output from said sensor and controlling turning of said motor. The control system further includes gear output angle variation estimation means for estimating a gear output angle variation of said reduction gear unit based on the motor turning angle. An angle transmission error is estimated based on the motor turning angle, whereby load tip locus accuracy can be improved without lowering responsivity of the control system.
