摘要
通过建立永磁同步电动机的数学模型和研究无位置传感器的控制技术,提出了在不同情况下检测电机转子位置方法。利用电机绕组中电压和电流信号,通过高频电流注入法和扩展卡尔曼滤波法对转子初始位置及转子运动时的转子位置进行检测。给出了基于DSP的无位置传感器永磁电机矢量控制系统设计方案。
The mathematic model of the synchronous machine was constructed and its control technique of mechanical - sensorless was investigated. The method of inspecting the PMSM rotor position in different conditions was proposed. Voltage and current signals of winding magnetic were used to check the initial rotor position and the position of revolving rotor by a high - frequency current injection and extended Kalman filter method. The space vector control system designing scheme of the permanent magnet synchronous motor based on DSP was presented.
