Abstract

The control of a permanent magnet synchronous motor brushless DC servo using the feedback linearization approach is considered. This approach will result in a fully linearized and decoupled system. Accurate measurement of the acceleration is required. A modified transformation is considered to obtain an incompletely linearized system by considering the load torque as a disturbance. The new system does not require an acceleration observer. A variable structure controller is used to improve the robustness of the system
