英文摘要
In latest motor control area, traditional voltage model is affected by variation of stator resistance and pure integration element of back electromotive force under the circumstance of low speed, whose effects would easily cause observation errors and lower motor speed control precision. Adaptive internal model control (AIMC for short) structure can adapt to stator resistance parameters variation and improve control precision. Cascaded Low pass filter (LPF for short) with compensation structure was proposed to revise amplitude and phase of observed flux linkage. The paper proposed the theory of AIMC and LPC, the structure would improve the accuracy of flux observer. At the same time, disturbance eliminating with compensation structure was put forward to improve the system anti-interference ability. Finally, PSIM 9.0.was used to build and simulate AC-DC-AC synchronous machine vector control system. Experiment results showed that the improved voltage model can effectively restrain the effects of stator resistance parameters variation. At the same time, precision of flux observer was effectively improved. Anti-interference ability of system was enhanced with nice tracking performance and robustness.
