Abstract

A novel application, employing the strategy of active disturbance rejection control and an extended state observer, is proposed to control the rotor shaft position of NASA´s high speed shaft (HSS) flywheel using active magnetic bearings. The robustness of the control is demonstrated in a frequency domain analysis and in simulations to be a major improvement of controls recently studied at NASA.
