Implementation of the State Feedback Control Scheme for a Magnetic Levitation System

摘要：

In this paper, we develop a state feedback control scheme based on αβγ filter for controlling the magnetic levitation system CE152. Unlike the observer-based control scheme which employs the system dynamics to form the state estimator, the proposed αβγ filter estimate the corresponding states based-on a Newtonian system. According to the αβγ filter, we not only can estimate the unmeasured state variables, but also can reduce the noisy signals. In addition to simulation, we practically implemented the controller in an experimental magnetic levitation system and investigated its tracking performance. The experimental results on the controlled system indicate the developed state feedback controller with αβγ filter is effective in face of external disturbances as well as nonlinearities inherent in the magnetic levitation system.
