Nonlinear Systems
I love the way this book analyzes every aspect of nonlinear control with such precision and depth. The treatment of core topics like stability, passivity, feedback linearization, and input-output methods is rigorous yet structured. Everything is well-defined, and the logical progression from foundational concepts to advanced topics makes it a powerful learning tool and reference. You do need a solid background in linear systems and linear algebra to fully appreciate the content; this isn’t an introductory book. But if you come prepared, the payoff is huge. Some readers noted that a few editions may be missing appendices or chapters, so double-check your copy.
