Robust Internal Model Control of Time-Delay Systems

Anisochronic Internal Model Control of Time Delay Systems

Time delay is a dynamic element that considerably complicates both theoretical and practical aspects of control system design. More or less satisfactory control of simple time delay systems that can be represented as a serial linkage of pure transportation delay and delay free system can be accomplished with Smith predictor. However, there is a lack of practically applicable control schemes for...

Delay-Dependent Robust Asymptotically Stable for Linear Time Variant Systems

In this paper, the problem of delay dependent robust asymptotically stable for uncertain linear time-variant system with multiple delays is investigated. A new delay-dependent stability sufficient condition is given by using the Lyapunov method, linear matrix inequality (LMI), parameterized first-order model transformation technique and transformation of the interval uncertainty in to the norm ...

Robust Control of Uncertain Time-delay Systems

The time delay in transport of material and energy is an inseparable part of many real industrial processes. Unfortunately, the presence of time-delay terms itself almost always brings problems in control and, quite naturally, the situation is even more complicated if this delay is uncertain. The source of the uncertainty can arise e.g. from simplifications during mathematical modelling, change...

Robust Control of Time-delay Systems

Delay-dependent Robust Control of Descriptor Systems with Time Delay

This paper deals with the problem of stability and robust control for both certain and uncertain continuous-time singular systems with state delay. Systems with norm-bounded parameter uncertainties are considered. Robust delay-dependent stability criteria and linear memoryless state feedback controllers based on linear matrix inequality are obtained. By choosing some Lyapunov-Krasovskii functio...
