The control voltage of the servo motor is output by the microcontroller and sent to 0832 for D/A conversion. The converted analog quantity is amplified and
level converted and sent to the PWM power amplifier circuit. The generated PWM wave drives the motor to rotate.
A tachometer generator is used to measure the rotational speed of the motor, and after amplification, it is sent to 0809 for A/D conversion, and then sent to the microcontroller ; the angular displacement of
the motor is directly sent to the port of 8751 from a 9-bit absolute photoelectric encoder to determine the position. feedback. The speed
regulator and position regulator in the control system will be completed by the 8751 application program.
