This paper presents model-based control (MBC) analyses of a bearingless interior permanent magnet motor (IPMM). The motor is capable of producing 100 kW power for use in high-speed applications in industries. The maximum speed of the motor is 22000 rpm. Motor's initial parameters are obtained through Finite Element Method (FEM) analyses. State-space models, controller and observer matrices are built based on the optimal, operating points obtained from FEM analyses. Thereafter, the rotor's magnetic levitation characteristics are analyzed through digital control strategies. Performances of the controlled system are recorded and subsequently discussed.

Modelling & Model-Based Control of a Bearingless 100 kW Electric Motor for High-Speed Applications

The traditional control strategies for electromagnetic levitation systems (EMLS) are the voltage or current control strategies based on linearization models at the equilibrium, but their effectiveness and efficiency of response are not satisfactory especially when load varies strongly. As a large amount of overshoot occurs, the adjustment time is intolerable long. A load adaptive control strategy based on a mass observer, which is able to apply the signals of current and air gap between electromagnets and tracks to predict the mass of load, is proposed in this paper. The mass can modify the Proportion Integration Differentiation (PID) parameters associated with the changed operating point. Via the comparison between simulation and experimental results, it is verified that the load adaptive control strategy performs more accurately and efficiently than traditional PID control strategies and fuzzy PID control.

A Load Adaptive Control Strategy for Electromagnetic Levitation Systems

The traditional control strategy of the electromagnetic levitation system (ELS) is a voltage or current control strategy based on the gap sensor and the current sensor. In this paper, an electromagnetic force sensor model is proposed and the mapping relation between electromagnetic force with current and levitation gap is obtained by Maxwell computation. The new force sensor model is used in ELS's control simulation and the result shows a new force sensor model can work well.
