Multivariable Feedback Control: Analysis and Design, Second Editionpresents a rigorous, yet easily readable, introduction to theanalysis and design of robust multivariable control systems.Focusing on practical feedback control and not on system theory ingeneral, this book provides the reader with insights into theopportunities and limitations of feedback control.

Taking into account the latest developments in the field, thisfully revised and updated second edition:
* features a new chapter devoted to the use of linear matrixinequalities (LMIs);
* presents current results on fundamental performance limitationsintroduced by RHP-poles and RHP-zeros;
* introduces updated material on the selection of controlledvariables and self-optimizing control;
* provides simple IMC tuning rules for PID control;
* covers additional material including unstable plants, thefeedback amplifier, the lower gain margin and a clear strategy forincorporating integral action into LQG control;
* includes numerous worked examples, exercises and case studies,which make frequent use of Matlab and the new Robust Controltoolbox.

Multivariable Feedback Control: Analysis and Design, Second Editionis an excellent resource for advanced undergraduate and graduatecourses studying multivariable control. It is also an invaluabletool for engineers who want to understand multivariable control,its limitations, and how it can be applied in practice. Theanalysis techniques and the material on control structure designshould prove very useful in the new emerging area of systemsbiology.

Reviews of the first edition:

"Being rich in insights and practical tips on controller design,the book should also prove to be very beneficial to industrialcontrol engineers, both as a reference book and as an educationaltool." Applied Mechanics Reviews

"In summary, this book can be strongly recommended not only as abasic text in multivariable control techniques for graduate andundergraduate students, but also as a valuable source ofinformation for control engineers." International Journal ofAdaptive Control and Signal Processing
