This paper considers the problem of passing from a linear time-invariant high order
controller designed for a linear time-invariant plant (of presumably high order) to a low order …

Robustness of control systems to disturbances and uncertainties has always been the
central issue in feedback control. Feedback would not be needed for most control systems if …

Modern methods of filter design and controller design often yield systems of very high order,
posing a problem for their implementation. Over the past two decades or so, sophisticated …

This book presents a synthesized design principle versus the existing separation principle of
modern control theory of over six decades since the start. Guided by this new principle, a …

A sufficient condition is derived for the existence of a stable suboptimal/spl Hscr//sup/spl
infin//controller. It is shown that if a certain algebraic Riccati equation, determined from a …

This paper considers controller order reduction with the consideration of closed loop stability
and performance. A closed loop structurally balancing method is proposed to reduce the …

The standard configuration for model‐based control design is reformulated into a twin
feedback configuration with the model and controller written in separate feedback loops …

This dissertation gives a number of contributions to the eld of controller reduction, by
providing some new frequency weighted or time-domain weighted model reduction …

摘要频域方法是控制理论与工程领域的一种基本研究手段, 许多控制问题都可归结为有限频域
性能指标的分析与综合问题. 广义Kalman-Yakubovich-Popov (KYP) 引理建立了频域方法(传递 …

This paper investigates the performance of coprime factor based controller reduction
methods. We show that under some mild conditions closed-loop performance bounds can …
