Research of Auto-Disturbances-Rejection Suspension Algorithm Based on Magnetic Flux Feedback

Abstract

The auto-disturbances-rejection suspension algorithm based on magnetic flux feedback has been brought up in this paper. The magnetic flux signal is not given by sensors, but it comes from nonlinear ESO (Extended State Observer). The nonlinear ESO designed in this paper has good dynamic characters that are only determined by the poles’ place of the compensated matrix. There is no relation between the dynamic characters and the format of nonlinear function. The experiment and simulation results denote that the new suspension control method designed in this has some advantages.
