Direct Control of Current Vector for Surface-mounted Permanent Magnet Synchronous Motor
摘要
Abstract
The key of control of a motor is the effective control of electromagnetic torque. A new control technique called direct control of current vector was proposed based on the comparison between the basic principles of vector control (VC) and direct torque control (DTC) for surface-mounted permanent magnet synchronous motor (SPMSM). Similar to VC, the basic idea was to control the amplitude and phase of stator current vector. Similar to DTC, this new control technique was based on two-phase stationary frame without decoupling of the stator current, and with two Bang-Bang controllers, the amplitude and phase of stator current vector were regulated through the selection of appropriate space voltage vectors, and then excellent dynamic torque response was achieved. Simulation results show that the direct control technique of current vector for SPMSM control system has excellent static and dynamic performance but with a small amount of calculation, and has strong robustness with little sensitivity to motor parameters.关键词
