摘　　要：针对P-隐式GPC算法在三输入三输出球磨机制粉系统中控制效果欠佳的问题,设计了双P-隐式修正GPC算法,在该算法的基础上加入主回路PID控制器的比例调节环节,并在预测输出环节增设带修正参数的条件模块,弥补传递函数阵阶次差距大造成的控制失调,适时修正了预测输出。仿真结果表明:该方法能够实现三输入三输出球磨机制粉系统的稳定控制,具有良好的适用性和鲁棒性。Considering the poor control effect of P-implicit GPC algorithm in the triple input/output ball grinder pulverizing system,a double P-implicit correction control GPC algorithm was presented,and basing on it,a proportional control was added to main loop PID controller together with a condition module with correction parameters in the output link prediction so as to offset the imbalance control caused by larger order gap of transfer function matrix and to correct the forecast output in time.The simulation results show that this method can realize the stability control in triple input/output ball mill pulverizing system because of its good applicability and robustness.
