摘要
针对燃煤锅炉蒸汽压力的滞后、耦合及高度非线性等特性,将Smith预估控制器理论应用到该系统,建立了控制环节的数学模型,利用Matlab软件做了仿真研究。仿真结果显示,系统跟踪速度快、超调量小,同时验证了控制算法的有效性。
For coal-fired boiler steam pressure system with hysteretic nature and coupled and highly nonlinear characteristics, Smith predictor controller theory is applied to the system. The mathematic model of the control link is set up and simulation applying Matlab software is discussed. The simulation result showed the high tracking speed and small overshoot and the effectiveness of the proposed algorithm.
