针对汽包锅炉给水过程的特点,采用了一种带在线辨识的自适应P ID控制器。利用递推最小二乘法循环调整P ID参数,并将该控制器应用于锅炉汽包水位三冲量控制系统。MATLAB仿真研究表明,与传统的P ID算法比较,该控制方案表现出了良好的动、静态性能,并能适应被控制对象参数的变化,具有较强的鲁棒性和自适应能力。 Aiming at the characteristics of drum boiler feed water process, an adaptive P ID controller with online identification is adopted. The recursive least square method was used to adjust the P ID parameters, and the controller was applied to the three-impulse control system of boiler drum water level. The simulation results of MATLAB show that compared with the traditional P ID algorithm, this control scheme shows good dynamic and static performance, and can adapt to the changes of the controlled object parameters with strong robustness and self-adaptive ability.
