  7. The precision and convergence of both rotor speed and flux estimation with ekf largely depend on the accuracy of the models of system noise and measurement noise. a global optimized noise covariance estimation method based on genetic algorithms ( ga ) is applied to ekf in foc system, a ga training simulation system of optimal parameters of ekf is given and the simulation results proves the effectiveness and robust of this algorithms

    本文用遺傳演算法（ ga ）對全閉環矢量控制系統中的ekf噪音模型進行離線優化辯識，模擬結果表明， ga尋優到的噪音模型使採用卡爾曼濾波器的無速度傳感器矢量控制系統獲得了與帶速度傳感器矢量控制系統相類似的動態性能，全系統對消息噪音和測量噪音有好的魯棒性。
