AI Technical Summary
Existing permanent magnet synchronous motor servo systems struggle to achieve high-precision tracking control when faced with complex nonlinear disturbances, especially friction and periodic torque fluctuations. Furthermore, existing methods lack robustness and are insufficient to effectively suppress disturbances under different operating conditions.
A composite disturbance suppression method is adopted, combining an extended state observer and an iterative learning controller. Through a digital controller, a power driver, a current sensor, and an angular position sensor, a proportional-integral control algorithm and a flutter signal generator are designed to achieve the observation and active suppression of disturbances.
Without requiring an accurate disturbance model, the periodicity and low-speed disturbances of the motor are effectively suppressed, improving the tracking accuracy and robustness of the motor, overcoming the limit cycle problem, and enhancing the control performance of the motor under different operating conditions.
