Angular Position Control of Permanent Magnet Synchronous Motor Using Compensation of the Nonlinearities of the DQ-Model

This paper proposes a simple nonlinear technique to control the angular position and d-axis stator current of a permanent magnet synchronous motor. Instead of making a linearization according to an operation point, the control laws, i.e., the dq-axis stator voltages are composed by two terms. The fi...

Summary:This paper proposes a simple nonlinear technique to control the angular position and d-axis stator current of a permanent magnet synchronous motor. Instead of making a linearization according to an operation point, the control laws, i.e., the dq-axis stator voltages are composed by two terms. The first one is to compensate the nonlinearities of the PMSM. The second component of the control law is determined by a linear controller to get the angular position. Thus, the design of the controller becomes easier. Simulation results prove the accuracy and robustness of the proposed angular position controller.
