Implementation of High Performance Nonlinear Feedback Control on Magnetic Levitation System

摘要

This paper presents the design of nonlinear state feedback that ensures high performance step response of magnetic levitation (maglev) system. The controller is designed for a maglev system in such a way that it exhibits the high speed response without exhibiting overshoot. This is achieved by keeping the damping ratio initially small and as the trajectory approaches to the command value, damping ratio is made high to avoid the overshoot in response. The designed controller is implemented on the experimental setup Maglev 730 system developed by ECP systems and results of the experiment are compared with the simulation results.
