Fundamentals of Robust Control by Zhou Kemin

This text references Zhou Kemin's seminal work "Essentials of Robust Control," highlighting its significance in control theory. Robust control represents a critical subfield focused on developing systems that maintain optimal performance despite uncertainties and external disturbances. This is typically implemented through advanced controllers designed with H-infinity or mu-synthesis methodologies, which mathematically guarantee stability margins against parameter variations and noise. The book serves as an essential resource, providing comprehensive coverage of robust control fundamentals alongside practical exercises that reinforce theoretical concepts. These exercises often involve MATLAB implementations using Control System Toolbox functions like hinfsyn for H-infinity controller synthesis or musyn for structured singular value analysis. The later chapters particularly feature problems that challenge readers to apply robustness analysis techniques to practical systems, such as evaluating stability using singular value plots (sigma function) and designing controllers that meet specific performance criteria under uncertainty conditions. The exercise sections prove invaluable for developing hands-on skills in robust control implementation, bridging theoretical principles with real-world engineering applications through systematic problem-solving approaches and computational verification methods.
