Alternative Title: A Study on driver of Permanent Synchronous Magnet Motor Using Sliding Mode Observer

Abstract: Recently brushless type permanent magnet synchronous motor is replacing the most common brush type motor in the automotive industry. Brush type DC motors have brush friction loss and noise, and the brush has limits of durability. Compared to DC brush motor, brushless permanent magnet synchronous motor has high efficiency and less noisy performance. To apply field oriented control of a brushless permanent magnet synchronous motors, it is required to know rotor position information. Commonly encoders or resolvers are used to know the position. These sensors has disadvantages of spacing and high cost problems.
In this paper, sliding mode observer is used as rotor position estimating algorithm. Sliding mode observer estimates induced stator voltage using the motor electrical equations. Experiment has been conducted using TI DSP TMS32028016PZA is used as controller.
