摘　　要：针对循环流化床锅炉燃烧系统具有非线性、强耦合、大惯性、大滞后的特性,在对无模型自适应控制算法改进的基础上,利用模糊控制适应性强的特点,设计出了无模型自适应控制器,实现了对循环流化床燃烧系统的四个子系统的控制。MATLAB仿真结果表明,改进后的无模型自适应控制器的控制性能更好、响应速度更快、计算量更小。The combustion system of the circulating fluidized bed boiler has the characteristics of nonlinearity,strong coupling,large inertia,and large hysteresis.Based on the improvement of the model-free adaptive control algorithm,the model-free adaptive controller is designed by taking advantage of the strong adaptability of fuzzy control.The control of the four subsystems of the circulating fluidized bed combustion system is realized.MATLAB simulation results show that the improved model-free adaptive controller has better control performance,faster response,and less calculation.
