Input Selection for Performance and Controllability of Structured Linear Descriptor Systems

Input Selection for Performance and Controllability of Structured Linear Descriptor Systems

A common approach to controlling complex networks is to directly control a subset of input nodes, which then controls the remaining nodes via network interactions. Current approaches for selecting input nodes assume that either all system matrix entries are known and fixed, or are independent free parameters, and focus either on performance or controllability. In this paper, we make two contrib...

Practical Stabilization and Controllability of Descriptor Systems

Practical stability is of significant practical importance in scientific and engineering problems but less investigated for descriptor systems. In this paper, the concepts of practical stability are developed to descriptor systems based on the idea of the generalized state which stands for the dynamic part of the state. To derive the main results of this paper, a comparison principle is establi...

PD Controller Design with H¥ Performance for Linear Systems with Input Delay

This paper presents H∞ control problem for input-delayed systems. A neutral system approach is considered to the design of PD controller for input delay systems in presence of uncertain time-invariant delay. Using this approach, the resulting closed-loop system turns into a specific time-delay system of neutral type. The significant specification of this neutral system is that its delayed coeff...
