说明：  该算法连续系统的积分分离式PID算法,用MATlab开发，能够管直接运行,当控制量与设定值偏差较大时，取消积分作用，以免积分作用过大引起系统的稳定性降低。
(The algorithm of the integral continuous system separate PID algorithm, developed using Matlab and can directly run the tube, when the control volume and settings deviation is larger, the abolition of integral action, so as not to cause too large integral role in the stability of the system lower.)
