摘要
研究了一种适用于压缩机的永磁同步电机无传感器全速度范围运行工况的控制方案。该方案在电机启动及低速阶段采用I/F速度开环、电流闭环的控制策略,中高速阶段采用基于改进的模型参考自适应无传感器控制策略,并实现两者的无冲击切换。对该方案进行了仿真和实验分析验证,研究结果证明了该方案的有效性。
A method applyed for compressor with PMSM sensorless and full speed range operation conditions was presented.An I/F control strategy with speed open-loop and current closed-loop was used at start-up and low speed stage of the motor.Sensorless control strategy which was based on an improved model reference adaptive system was used at middle or high-speed stages,and realized no impact switch of two control strategies.The analysis results of simulations and experiments prove the validity of this method.
