摘要
基于非线性backstepping方法,针对典型单元机组的机、炉协调系统非线性模型,引入虚拟控制变量,逐步构造出偏差信号的李雅普诺夫函数,设计出了综合非线性控制器。该控制器不仅保证了系统稳定性,而且能够实现跟踪误差收敛于零。仿真试验验证了这种非线性方法在协调系统控制器设计中是可行的。
Aiming at the typical model of boiler-turbine coordinate system and based on nonlinear method of backstepping, some dummy variables are introduced to construct the Lyapunov function of error signals. A synthetic nonlinear controller is designed. This method is proved to be feasible through simulation.
