Homopolar flywheel is considered to be very efficient and a good candidate for next-generation energy storage device, compared to the conventional (heteropolar) flywheels. By the help of active magnetic bearings, in this paper we are proposing a method to control the attitude of this low-loss flywheel. Many studies had been established in the past using gain-scheduling control and other methods but these need additional information (i.e., flywheel rotation speed) as an input. Without this information, it was difficult to control the flywheel. Here we introduce a new and more robust method using Multi-Input Multi-Output Simple Adaptive Control (MIMO-SAC) with an improved adaptive identification.
