Abstract |
The stator currents of the brushless dc (BLDC) motor are controlled to control the torque of the motor
using the rotor position signal. For many applications, the load torque varies along the motor position
trajectory such as for robotic applications.
In this paper, an online control strategy is proposed for nonlinear brushless dc motors operating in a
high-performance drives environment. The proposed control strategy possesses the capabilities of
simultaneous online control. The first goal is to control the speed and position of the rotor, while the
second goal is to control the components of the stator current. The control action is implemented in
such a way that system trajectories follow a predetermined reference track. |
