Bounds for Closed-Loop Transfer Function Matriceds of Robust Decentralized Control Systems

摘要: 本文将Nyquist阵列用于对象模型具有非结构不确定性的分散控制系统.在假定返回差 矩阵为广义块对角优势的条件下,得到了当某个子块反馈为开路(或某个反馈回路为开路)时 的闭环传递矩阵(或闭环传递函数)的界及其特征值的包含域.这是标准的Ostrowski带的再 推广.Abstract: The Nyquist arrays are applied to decentralized control systems with plants of unstructured uncertainties. By the assumption that return difference matrices are generalized--block diagonally dominant, bounds for closed-loop transfer function matrices (or for closed-loop transfer functions) and the inclusion regions for their eigenvalues are obtained when a certain block of feedback loops are open (or a certain feedback loop is open). These are further generalizations of the standard Ostrowski band.
