Systematically presents the input-output finite-time stability (IO-FTS) analysis of dynamical systems, covering issues of analysis, design and robustness. The interest in finite-time control has continuously grown over the past fifteen years, with this book specifically addressing linear time-varying systems and hybrid systems. It delves into analysis, design, and robustness issues while including practical applications to real-world engineering problems. Key features include detailed discussions on IO-FTS, a more practical concept for real engineering applications, making it an essential resource for researchers and practitioners in the field.
