This paper describes the basic principle of velocity pursuit guidance law and body pursuit guidance law of trajectory correction projectiles , researches the terminal correction trajectory and miss distance under pursuit guidance laws by 6—DOF trajectory simulation program, researches the orbit of laser detector ray axis and ground projection area of laser detector spatial viewpoint.

文中对速度追踪制导律和弹体追踪制导律的工作原理进行了研究，利用六自由度弹道仿真程序对弹道修正弹两种追踪方式下的末段修正弹道和脱靶量进行了对比计算，研究了两种追踪方式下激光探测器光轴的轨迹及激光探测器空间视场在地面投影区域的变化；弹体追踪方式命中精度虽然较低，但由于工程实现简单、成本低，仍有其工程使用价值。

The key points of sensorless technology in PMBLDCM are to study a method which can detect rotor position accurately by simply method in whole speed range. After analyzing current sensorless methods of the PMBLDCM, it is found that those methods are successful at middle and high speed, but they often fail to detect rotor position at low speed when the back electromotive force is small or zero.

纵观目前的永磁无刷直流电机的无位置传感器控制方法，比较成熟而可行的方法多集中于电机在中高速区域运行时，能够较准确估计转子位置；电机处于低速、极低速、静止状态时电加热管，因为反电动势幅值较小或者为零，而无法正常工作。
