PURPOSE:To make control response time to the change of reference input the shortest by controlling the sampling time of the program execution of major loop control in response to the change of the reference input of major loop control. CONSTITUTION:The digital computer 8 has a speed control program 2, a current control program 3, a phase control program 4, a speed reference discriminating program 10 and a sampling time program 9. The current control program 3, the phase control program 4 and the speed reference discriminating program 10 are executed in succession at every fixed sampling time according to the sampling time program 9 in the digital computer 8. Speed reference is given to the speed control program 2 and the speed reference discriminating program 10 in the digital computer 8 from a speed reference circuit 1. The speed reference discriminating program 10 discriminates the change of the speed reference, and controls the sampling time. |
