Sliding mode control for electromagnetic levitation system based on feedback linearization

Magnetic levitation system has developed into a significant consideration in designing systems which require low losses due to friction and low energy consumption. In this paper the levitation inflexibility for suspending a steel ball and its distinctive application to wipe out friction and build machining accuracy is talked about. The procedures of feedback linearization and sliding mode control are proposed in this paper to accomplish relentless levitation. The procedure of feedback linearization is utilized as a part of this paper to change a nonlinear electromagnetic levitation framework into a linear framework. The proposed controller of sliding mode control is received for enhancing the power and robustness of the electromagnetic levitation system in the vicinity of commotions. Simulation results of sliding mode control demonstrate that the system has more prevailing and powerful bent of stifling disturbance and high inflexibility as equated with that utilizing traditional PID control strategy.
