Neglecting the time canstants, axial accelerations and the control overflow, the optimal strategy is reduced to the conventional proportional navigation guidance law.
当不计飞行器的响应时间、纵向加速度和控制溢出时，蜕化为常规比例导引。
2
Frequency control is in reducing the output frequency at the same time the output voltage has been reduced accordingly, the output voltage proportional to torque.
变频调速控制是在降低输出频率的同时输出电压也相应降低，转矩正比输出电压。
3
PID control: through the adjustment of the proportion of the output current, the relevant parameters are proportional, integral time and differential time;
