Performance investigation of Permanent Magnet Synchronous Motor drive using vector controlled technique

摘要

The rotor position is necessary to achieve the vector control drive system of Permanent Magnet Synchronous Motor (PMSM). In this thesis, the resolver sensor detecting the rotor position of PMSM is focused. PMSM has been widely used in high performance drive applications for its advantages such as compactness, high efficiency, reliability, and suitability to environment. Due to its high power density and smaller size, PMSM has evolved as the preferred solution for speed and position control drives on machine tools and robots. A PMSM is a motor that uses permanent magnets to produce the air gap magnetic field rather than using electromagnets. These motors have significant advantages, attracting the interest of researchers and industry for use in many applications. PMSMs are widely used in low and mid power applications such as computer peripheral equipments, robotics, adjustable speed drives and electric vehicles. In order to overcome the inherent coupling effect and the sluggish response of scalar control the vector control is employed. By using the vector control, the performance of the AC machine can be made similar to that of a DC machine. In this thesis to achieve high performance the vector control of the Permanent magnet synchronous motors drive are used for different reference constant speed and mechanical load torque is employed. The simulation of PMSM drives with vector control technique is developed using environment. The effectiveness of the proposed control method is verified by simulation based on MATLAB/SIMULINK environment.
