| 摘 要： | 针对无速度传感器的调速系统，提出一种将电压／频率控制与矢量控制相结合的实现方案，该方案先采用电压／频率控制策略启动时机，并利用扩展卡尔曼滤波估测转子转速，当转速接近给定转速时，转换到矢量控制，系统仿真结果表明这种方案具有较好的动态和静态性能。

| Abstract: | Aiming at te speed regulation system without a speed sensor, a new method that the U/f control is confined with the vector control is introduced. The U/f control strategy is used to start the motor, meanwhile the rotor speed is estimated by using the extended kalman filter. When the estimated speed approximates to the given speed, the U/f control is replaced by the vector control. Simulation results show that this method is good on both dynamic and static performances. |
