Abstract

See full text

A designing method for a fractional order proportional derivative (FOPD)-generalized extended state observer (GESO) controller includes the following steps: S1, selecting an FOPD controller and a GESO to control a motor speed loop, and designing the FOPD controller and the GESO; S2, performing compensation and simplification on a control object of the speed loop by using total disturbance estimated by the GESO to obtain a compensated speed loop control model, the compensated speed loop control model reflecting the characteristics that tracking performance is only related to the FOPD controller, and that anti-interference performance is only related to a bandwidth ωo of the GESO; and S3, respectively solving unknown parameters in the FOPD controller and the GESO. The present method achieves non-overshoot tracking of the speed of a permanent magnet synchronous motor, has excellent anti-interference performance, and resists external load and model changes.
