Abstract EN
Compared with current mode flywheel torque controller, speed mode torque controller has superior disturbance rejection capability.
However, the speed loop delay reduces system dynamic response speed.
To solve this problem, a two-degrees-of-freedom controller (2DOFC) which consists of a feedback controller (FBC) and a command feedforward controller (FFC) is proposed.
The transfer function of FFC is found based on the inverse model of motor drive system, whose parameters are identified by recursive least squares (RLS) algorithm in real-time.
Upon this, Kalman filter with softening factor is introduced for the improved parameters identification and torque control performances.
Finally, the validity and the superiority of the proposed control scheme are verified through experiments with magnetically suspended flywheel (MSFW) motor.
