Luenberger Observers: Separation Principle

This lecture covers the concept of Luenberger observers in multivariable control systems. The instructor explains the motivation behind using state observers, the challenges faced, and the solutions provided by building an observer. The lecture also delves into the terminology, stability, and performance of state observers. Additionally, it discusses full-order observers, the separation principle in output-feedback controllers, and the design of observers and state feedback controllers. The importance of observer stability and the dynamics of error estimation are highlighted, along with the design considerations for Luenberger filters. The lecture concludes with a discussion on reduced-order observers and their applications.
