Patent ID: 8598832

Claim:
A control system of multi-shaft servo motor, wherein, comprises: a position loop module ( 400 ) for receiving a position loop given value and a position feedback value of respective shelves and figuring out a velocity loop given value; a velocity loop module ( 500 ) for receiving the velocity loop given value and a velocity feedback value of respective shelves and figuring out a current loop given value; a current loop module ( 200 ) for receiving the current loop given value and a current feedback value of respective shelves and outputting a current loop output value; a PWM signal generation module ( 300 ) for receiving the current loop output value from the current loop module ( 200 ) and generating a PWM signal for controlling respective shelves of the servo motor; and a multi-shaft time sequence control module ( 700 ) for controlling the position loop module ( 400 ), the velocity loop module ( 500 ), the current loop module ( 200 ) and the PWM signal generation module to receive and process the signals.
