【摘要】：针对一类带有多干扰的非线性时变时滞关联系统,考虑了复合抗干扰控制器设计问题.复合抗干扰控制器的设计主要结合了基于干扰观测器的控制方法(Disturbance observer based control,DOBC)和H_∞控制方法.系统受到的干扰可以分为两类:第一类干扰由外部系统描述,并且与控制输入在同一通道;第二类干扰假定满足有界H_2范数.设计干扰观测器估计第一类干扰,并利用干扰估计值进行前馈补偿;利用H_∞控制方法对第二类干扰进行衰减.利用Lyapunov函数理论分析了闭环系统的稳定性,并以线性矩阵不等式的形式给出了可解的时滞依赖条件.最后,利用数值仿真验证了所提方法的有效性.
[Abstract]:For a class of nonlinear time-varying time-delay correlated systems with multiple disturbances. The design of composite anti-jamming controller is mainly combined with the control method based on disturbance observer (. Disturbance observer based control. The disturbance of the system can be divided into two categories: the first type of disturbance is described by the external system and is in the same channel as the control input; The second kind of disturbance is assumed to satisfy the bounded H _ s _ 2 norm. A disturbance observer is designed to estimate the first type of disturbance and feedforward compensation is performed by using the disturbance estimation value. The second kind of disturbance is attenuated by H _ 鈭，
