Abstract :
For PMSM position system with parameters uncertainty, traditional control means have simple design and good steady performance, but system robustness can not be ensured. To solve the problem, a robust quadric control method has been put forward, which is based on state transformation. By the transformation, drive system and position controller of the motor are viewed as a whole, then a linear state feedback controller is designed uniformly. This control method not only remains conventional control structure and itpsilas advantage on static performance, but also greatly increases robustness to changes in system parameters on dynamic performance. Simulation results demonstrated the implementation simplicity and effectiveness of this control method.
