摘要
火电厂磨煤机负荷控制对象具有典型的非线性、大滞后及时变性等复杂特性,因而采用常规的控制方法难以获得较好的控制效果。基于预测控制在解决复杂难控对象的优势,提出MAC控制方案用以解决磨煤机负荷控制问题。良好的仿真效果表明,针对不同工况下的模型参数变化及内部扰动时,MAC控制算法在控制的稳定性、鲁棒性、抗干扰性上均优于常规的PID控制。
Based on the advantage of predictive control in solving the complex control object, this paper put for- ward a MAC control scheme to solve the problem of coal mill load control. Good simulation results show that, in view of the model parameters and internal disturbances under different working conditions, the MAC control algorithm for the control of stability, robustness, anti - interference performance is superior to conventional PID control.
