Well-designed current control loop can provide a smooth and fast torque response to AC motor and efficiently protect the motor and drive’s hardware circuit. In addition, it also simplifies the control design and parameter tuning for the velocity loop and position loop. Sinusoidal commutation can be divided into two categories: three-phase current control and field oriented control (FOC). However, there is few existing literature focusing on systematically comparing the performance of the above two sinusoidal commutation techniques. The goal of this thesis is to study the current control based on the sinusoidal commutation for the permanent magnet synchronous motor. In order to compare the differences between three-phase current control and field oriented control, the Matlab/simulink software is used to construct a simulation system to discuss the dynamic response of current control, design of servo parameter, and robustness of controller. In addition to theoretic analysis, the dsPIC30F4011 by Microchip is employed in this thesis as a core of the control system to realize field oriented control by well-designed hardware circuits and software programs. A commercial 1 hp servo motor is used as the test platform to evaluate the performance of the servo drive developed in this thesis. According the experimental results, the servo drive developed in this thesis can control the servo motor with external load to perform acceleration/deceleration under the torque mode and the velocity mode.
