PI_GPC_1
比例积分型的GPC，由新的目标函数解出的控制率与常规PI控制有着一样的形式，这样就获得了一种具有PI结构的广义预测控制，而且其参数、有着明显的工程意义，整定原则基本类似于PID。(Proportional-integral-type GPC, the new objective function solution of the control rate with conventional PI control has the same form, so to obtain a PI structure with generalized predictive control, and its parameters, there is a clear sense of the project, setting basic principle is similar to PID.)
