Representations of Linear Dynamic Systems,coupling problems in later chapters. Multivariable linear dynamic systems and their representations are introduced. Polynomial and rational function matrices are studied in details. Matrix fraction descriptions and multivariable poles and zeros are covered. State-space realizations from matrix fract

Stability and Robustness of Feedback Systems,this chapter. Section 1 addresses internal stability of general interconnected systems and derives a powerful stability condition which is applicable to systems with any feedback and/or feedforward combinations. Section 2 focuses on the conventional unity output feedback configuration and gives the

Transfer Matrix Approach,eveloped in both state-space and polynomial matrix settings. However, time delay often exists in industrial processes and other systems, some of which will be highlighted in Section 1. We need an entirely new approach to decoupling problem for plants with time delays. Time delay imposes a serious di

Delay Systems,nts in operations. Input-output loops in a multivariable plant usually have different time delays, and for a particular loop its output could be affected by all the inputs through likely different time delays. As a result, such a plant can be represented by a multivariable transfer function matrix h

Near-Decoupling,esign though robust stability is checked sometimes. It is noted that exact decoupling may not be necessary even in the nominal case for many applications and usually impossible in the uncertain case. What is really needed instead is to limit the loop interaction to an acceptable level. In this chapt

Introduction,s the so called “controller”. It could either be a piece of hardware or software code in a computer. Its job is to receive information about the system from a variety of sensors, process it, and automatically generate commands for corrective action to bring the variable of interest to its desired va
