Title: Servomotor controller
Inventor: YAMAMOTO YOICHI
IPC: H02P29/00
Filed: 1989-02-20
Abstract: PURPOSE:To improve speed control properties for torque disturbance by using as a current command the total of the output of a controller for torque disturbance compensation inputting the difference between the proportional part of the difference of a position detection value from a position command value and a speed command value and the output of a speed controller inputting said speed command value. CONSTITUTION:A command generator 16 considers characteristics of a position feedback loop by a primary delay element to generate a speed command value Vsf. A disturbance torque compensation controller 30 inputs the difference between the output value Vr of a position controller 19 and said speed command value Vsf to obtain an output value Ig. A speed controller 12 sets  V=Vsf-Vd and thereafter conducts the same operation as usual to obtain its output value Ir. A current command value Is is obtained as the total of the output value Ir of said speed controller 12 and that of said disturbance torque compensation controller 30 and outputted to a D/A converter 14. Thus, it is possible to conduct a sufficient gain setting also for disturbance torque without making a servo system oscillatory and to reduce the time delay of a speed variation for various torque disturbances and the corrective operation of said speed variation.
