<P>PROBLEM TO BE SOLVED: To improve the unbalances of integral values of integral elements of speed control units in the tandem control and to avoid the deterioration of the controllability of a motor and the overheat of the motor. <P>SOLUTION: This motor controller practices the tandem control wherein one drive object 4 is driven by a plurality of motors 15 and 25. Position control units 11 and 21, speed control units 12 and 22, current control units 13 and 23, current amplifiers 14 and 24, and speed detectors 17 and 27 are provided for the respective motors. Position detectors 18 and 28 may be provided for the respective motors or one position detector may be provided for one motor. Further, a speed integrator common means 5 which makes the integral values of the integral elements of the speed control units 12 and 22 common is provided. Same position commands are inputted to the control system of the motors under the tandem control, and the integral values of the integral elements of the speed control units are held at values approximately equal to each other by the speed integrator common means 5. <P>COPYRIGHT: (C)2003,JPO |
