The proposed control method is testified by computer simulation and improves the robustness of the Permanent Magnet Synchronous Motor control system. 0.Introduction Permanent Magnet Synchronous Motors(PMSM) are widely used in various fields of industrial production , civil life , aerospace and military defense due to the advantages of high power density, high efficiency , high reliability and fast dynamic response.
Though the current feed-forward control method is simple and easy- engineering applications , still the system performance is greatly reduced with bad system robustness in the case of motor parameters unknown; The internal model control has advantages of enhancing system robustness and better decoupling effect.

Abstract The netlike cracks along the rebars at the bottom of concrete slabs as well as the circular
cracks around the columns and beams were found in an underground park, which is a cast-in-site
concrete frame.
