In this book the authors reduce a wide variety of problems arising in system and control theory to a handful of convex and quasiconvex optimization problems that involve linear matrix inequalities. These optimization problems can be solved using recently developed numerical algorithms that not only are polynomial-time but also work very well in practice; the reduction therefore can be considered a solution to the original problems. This book opens up an important new research area in which convex optimization is combined with system and control theory, resulting in the solution of a large number of previously unsolved problems.

In times of constant change, adaptive leadership is critical. This Harvard Business Review collection brings together the seminal ideas on how to adapt and thrive in challenging environments, from leading thinkers on the topic—most notably Ronald A. Heifetz of the Harvard Kennedy School and Cambridge Leadership Associates. The Heifetz Collection includes two classic books: Leadership on the Line, by Ron Heifetz and Marty Linsky, and The Practice of Adaptive Leadership, by Heifetz, Linsky, and Alexander Grashow. Also included is the popular Harvard Business Review article, “Leadership in a (Permanent) Crisis,” written by all three authors. Available together for the first time, this collection includes full digital editions of each work. Adaptive leadership is a practical framework for dealing with today’s mix of urgency, high stakes, and uncertainty. It has been used by individuals, organizations, businesses, and governments worldwide. In a world of challenging environments, adaptive leadership serves as a guide to distinguishing the essential from the expendable, beginning the meaningful process of adaption, and changing the status quo. Ronald A. Heifetz is a cofounder of the international leadership and consulting practice Cambridge Leadership Associates (CLA) and the founding director of the Center for Public Leadership at the Harvard Kennedy School. He is renowned worldwide for his innovative work on the practice and teaching of leadership. Marty Linsky is a cofounder of CLA and has taught at the Kennedy School for more than twenty-five years. Alexander Grashow is a Senior Advisor to CLA, having previously held the position of CEO.

This book discusses analysis and design techniques for linear feedback control systems using MATLAB® software. By reducing the mathematics, increasing MATLAB working examples, and inserting short scripts and plots within the text, the authors have created a resource suitable for almost any type of user. The book begins with a summary of the properties of linear systems and addresses modeling and model reduction issues. In the subsequent chapters on analysis, the authors introduce time domain, complex plane, and frequency domain techniques. Their coverage of design includes discussions on model-based controller designs, PID controllers, and robust control designs. A unique aspect of the book is its inclusion of a chapter on fractional-order controllers, which are useful in control engineering practice.
