摘要：
A bearingless switched reluctance motor (BSRM) is a multi variable, nonlinear and high coupling system. So the design of its control is very complicated. Based on basic electromagnetism theory, the paper derived a radial force model of a bearingless switched reluctance motor. Reversibility of the model is proved and inverse system approach is developed to realize the dynamic decoupling of radial force. A nonlinear controller based on inverse system is designed so that the nonlinear, strongly coupled system is decoupled into two linear subsystems. Linear control system techniques are applied to these decoupled linear subsystems to synthesize desired response. To verify the effectiveness of the control scheme, some simulations are carried out and the results are satisfactory.
