说明：  积分分离PID算法的思想是：当被控量与设计的偏差量偏差较大时，取消积分量，以免积分量使系统稳定性降低，超调量增大；当被控值接近定值时，引入积分控制，以消除静差，提高系统精度。(integral separation PID algorithm thinking is this : When the volume charged with the design of larger deviations deviation, the abolition of Integral volume, the volume so integral to reduce the system stability, over-regulation increased; When charged with setting value approach, the introduction of integral control to eliminate static error and improve system accuracy.)
