Variable Bias Type AMB Flywheel Powered Electric Vehicle without any Touchdown against Load Disturbance
This paper deals with a stabilization control of active magnetic bearings (AMBs). Conventionally, zero bias method was chosen in stabilization control for its advantage in minimizing stabilization energy. However stiffness of the method is low, and touchdown may occur when the vehicle moves at high acceleration rate. We introduce bias current in fixed or variable rate using generalized switching rule for zero/nonzero bias control with regards to current saturation. Depending on external disturbance, it acts as a zero bias controller or bias controller.
