Abstract

PURPOSE: To eliminate the checking of the maximum acceleration, by installing the oscillator, the comparator and the counter to the control device to extract the relative velocity so as not to exceed the maximum acceleration the servo system can obtain and thus by controlling the servo system.
CONSTITUTION: Counter 4 counts the output of oscillator 2 having the frequency decided in correspondence to the maximum acceleration the servo system can obtain. This output is compared with designated velocity vc at the 1st comparator 1 and then applied to the 2nd comparator 7 via counter 4 again. On the other hand, the difference between target position xc and relative position xr to be generated later is applied to the 2nd comparator 7 via subtractor 5 and the square root generating ROM. Then the output of comparator 7 is applied to DA converter 9 to obtain relative velocity vr. And at the same time, the frequency corresponding to velocity vr is produced by frequency converter 10 to be applied to counter 11. In such way, both velocity vr and position xr are obtained, and these outputs are applied to servomotor 15 via amplifier 14, encoder 16 and others. Thus the rotational frequency of motor 15 can be controlled.
