Nonlinear feedforward control of brushless DC motors (BLDCM)
Proceedings of the IEEE International Symposium on Industrial Electronics, 2002In this paper, we propose a new feedforward control scheme for the control of brushless DC motors. We adopt a novel disturbance torque suppressor to eliminate the effects of the disturbance torque, uncertain inertia moment, and nonlinear friction, so that the new controller makes the velocity error to be zero at any state even when the moment of ...
