The book focuses on the issues of secure fusion estimation and control in cyber-physical systems under cyber-attacks, such as privacy protection under eavesdropping attacks, security fusion estimation under DoS and FDI attacks, and model-based and model-free security control under cyber-attacks. The comprehensive and systematic treatment of security protection in cyber-physical systems is one of the main features of the book, which is particularly suitable for readers interested in learning practical solutions for the security of cyber-physical systems. The book can benefit researchers, engineers and graduate students in the fields of control science and engineering, computer science, communication engineering, etc.
