The book "Time-Dependent Switched Discrete-Time Linear Systems: Control and Filtering" offers a comprehensive analysis of the fundamental issues of control and filtering for discrete, time-dependent, switched linear systems. It addresses the challenges posed by time-dependent switching signals and provides a detailed introduction to the theoretical foundations and motivations behind switched systems. The initial chapters introduce the topic and provide a literature review, while the subsequent chapters explore various methods for the stability and performance of these systems. Special attention is given to the problems of control and filtering in the presence of uncertainties and disturbances. The book is a valuable resource for professionals and students engaged in the theory and application of switched systems in control engineering.
