摘要: 基于HM(Heterogeneous Model)非线性系统模型,提出并研究了滚动时域H∞控 制器的设计.给出了基于H∞性能指标的最优控制律和其存在的充分性条件,该控制律可以 保证系统稳定和干扰衰减增益不超过某一上限.然后,为了减少计算量,设计了有上述相同性 能保证的次优控制器.Abstract: This paper concentrates on the problem of receding horizon H∞ control for a family of nonlinear systems that can be represented by a heterogeneous model (HM). Under H∞ performance index, the sufficient conditions are derived for the optimal controller which guarantees the stability with disturbance attenuation. Then, in order to reduce the computational burden, a suboptimal controller which can guarantee the same system performance is designed.
