Parameter Variations

The problem of precise control of the air – gap of magnetic levitation vehicles is considered in this paper. A sliding mode controller is designed for the levitation control task. Robustness of the controller was investigated using computer simulations. The results show that the controller is robust to parameter variations of up to ±13% and can tolerate disturbances up to ±400N/Kg.

Second Order Sliding Mode

This article presents the implementation results of second order sliding mode control (SOSM) for magnetic levitation system. In practical systems, especially when the actuators are electro-mechanical, the conventional (first order) sliding mode control can not be used effectively as it exhibits chattering, which is highly undesirable. Therefore, for such systems, sliding mode control of higher order can be a suitable choice as the reduce the chattering significantly. In this article the super-twisting control, which isa second order sliding mode control, is designed and implemented for the experimental setup of Maglev system, Model 730 developed by ECP systems.
