To overcome the defects of pure integrator initial value of the integral, the cumulative error and DC offset, permanent magnet synchronous motor stator flux observer method is proposed based on full-order state observer. The stator flux as state vector to construct the system state equation, the current as output vector to construct the system output equation, configuration observer poles proportional to the motor model pole, and use of the robust pole assignment algorithm in Matlab for calculate of observer feedback gain matrix. Experiments show that use of full-order state observer for the stator flux observed has higher accuracy, and it form of direct torque control system has better performance.
