摘要
针对火电厂煤粉炉燃烧控制系统大惯性、大延迟且模型不确定,以及常规PID串级控制难以取得良好控制效果的特点,提出广义预测控制与PID相结合GPC-PID的控制策略。仿真结果证实了该控制策略较常规PID有较好的控制性能和较强的抗干扰能力。
For Boiler Combustion Control System with large inertial,time-delay, uncertain model and the bad result of PID Cascade Control System, it was presented the control strategy of generalized predictive control associated with PID cascade control. Simulation results compared with PID had the property of good dynamic and static characteristics,anti-interference ability.
