Time delays are important components of dynamical systems, whether in engineering, physics, economics, or the life sciences. Through a unifying eigenvalue-based framework, this monograph presents an overall solution to stability analysis, stabilization, and the robust fixed-order control problem for time-delay systems. The authors offer a range of both analytical methods and numerical algorithms, applicable to a broad class of linear time-delay systems that includes retarded- as well as neutral-type systems. Integrating leading-edge research from control theory, optimization, numerical linear algebra and bifurcation analysis, this book has high relevance across systems and control theory, computer science, applied mathematics and computational mathematics alike. New to this edition is the inclusion of both retarded-type and neutral-type systems; a broader scope of solution includes not only stabilization but the design of robust and optimal controllers; while an increased range of applications from electrical engineering to biology showcases the effectiveness and generality of the solution more effectively.
