The current regulator, the speed regulator and the flux regulator were designed in the closed- loop control system. Linearization theory of nonlinear systems was used to eliminate the coupling terms of the current regulator and to achieve the linearization of the current regulator. The parameter was adjusted using the engineering design method and the tuning result was applied to the three-level inverter vector control system. Experimental results show that the system has good dynamic and static characteristics.The results demonstrate the effectiveness and feasibility of the system.
