track switching

According to the phase trajectory of along-track drift, the switching function with the oblique lines was designed in order to converge the initial errors, and the limit cycle was analyzed correspondingly.

分析了构形沿航迹漂移的相轨迹，针对单开关门限控制律不能对初始误差收敛的问题，设计了倾斜开关曲线控制，并分析了相应的极限环参数。

In the compensation current tracking control, the system adopts hysteresis control method of timing comparison, which can make the output current of main circuit track the directive current and limit the maximum switching frequency of the main circuit switching device.

对于补偿电流的跟踪控制，采用定时比较的滞环控制法，使得主电路的输出电流能够跟踪指令电流的变化，并且限制了主电路开关器件的最高开关频率。
