摘要
通过改变广义预测控制(GPC)的目标函数,将PID控制与广义预测控制相结合,得到了具有PID算法结构的广义预测控制(PIDGPC)。建立了刮膜式分子蒸馏过程的数学模型,并将PIDGPC算法应用于该数学模型,仿真结果表明,PIDGPC明显改善了GPC算法的超调、动态性能。
By changing the cost function of generalized predictive control(GPC),the PID algorithm is combined with the Generalized Predictive Control algorithm to get PID-type Generalized Predictive Control(PIDGPC) algorithm.The mathematical of the scrape-membrane molecular distillation process is established and the experiments show that the PIDGPC obviously improve the overshoot and poor dynamic properties of the GPC.
