Control and Estimation of Systems with Input/Output Delays

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Time delay systems exist in many engineering elds such as transportation, communication, process engineering and more recently networked control s- tems. In recent years,time delaysystems haveattracted recurring interests from research community. Much of the research work has been focused on stability analysis and stabilization of time delay systems using the so-called Lyapunov- Krasovskii functionals and linear matrix inequality (LMI) approach. While the LMI approach does provide an e cient tool for handling systems with delays in state and/or inputs, the LMI based results are mostly only su cient and only numerical solutions are available. For systems with knownsingle input delay, there have been rather elegant- alytical solutions to various problems such as optimal tracking, linear quadratic regulation and H control. We note that discrete-time systems with delays can usually be converted into delay free systems via system augmentation, however, theaugmentationapproachleadsto muchhigher computationalcosts,especially for systems of higher state dimension and large delays. For continuous-time s- tems,time delayproblemscaninprinciple betreatedby thein nite-dimensional system theory which, however,leads to solutions in terms of Riccati type partial di erential equations or operator Riccati equations which are di cult to und- stand and compute. Some attempts have been made in recent years to derive explicit and e cient solutions for systems with input/output (i/o) delays. These include the study ontheH controlofsystemswith multiple input delaysbased on the stable eigenspace of a Hamlitonian matrix [46]. Artikel-Nr. 9783540711186
