WebThis video introduces users to Describing Function Method used to analyse nonlinear systems About Press Copyright Contact us Creators Advertise Developers Terms … WebThe control-oriented dynamic model is first developed by extended describing function method. In order to achieve an optimised output voltage dynamic response, the sliding surface is derived based on the input–output linearisation concept. The proposed sliding-mode controller provides inherent strong robustness against the dynamic drift issues.
