中文摘要：
针对感应电机无速度传感器间接磁场定向控制系统中传统PI控制器和磁通观测器的不足，利用感应电机的时变参数模型的降阶处理方法，提出一种变增益的PI速度控制器：为获得无速度传感器控制，提出一种非线性鲁棒高增益观测器。仿真和试验验证表明：PI速度控制器不但能根据实际工况实现PID参数的在线调整，而且工程实现简单，减少了系统在启动阶段的超调；非线性鲁棒高增益观测器只需要电机的定子电压和电流，能同时观测电机的状态量和转子时间常数等参数，鲁棒性好，计算量少，易于适时在线实现。
英文摘要：
Based on the reduced order of the IM model of the sensor-less indirect field oriented control （IDFOC） system, a simple variable gain PI speed controller was presented. In order to implement the sensor-less control, a high gain observer （HGO） was proposed to estimate the rotor fluxes, speed and time constant using the stator currents and voltages. Simulation and experimental results show that the proposed method can adjust the PID parameters online, the engineering implementation is very easy, and the speed overshot decreases during the startup. HGO has many advantages, such as good robustness, less computation, and real time identification of the IM.
