摘要
介绍了一种检测无位置传感器开关磁阻电机(SRM)无迟滞起动转子初始位置估算法。通过向电机定子相绕组注入瞬时测试脉冲来准确估算转子初始位置 ,从而实现转子处于任何位置时的无迟滞起动 。
A novel method for rotor position estimation is presented for switched reluctance machine starting free of position sensor and hesitation.By applying a DC pulse to the stator phase windings for a short moment,the initial rotor position can be accurately detected,and the sensorless control without starting hesitation can be achieved.Critical issues related to optimal model selection as the virtual sensor are discussed in detail.Computer simulation and experimental results are included.
