Output Feedback Sliding Mode Design for Linear Uncertain Systems

This paper considers the development of output feedback sliding mode controllers for a class uncertain systems. Firstly,it studies the development of static output feedback sliding mode controllers.Then if the so called conditions are not satisfied, a compensator must be considered.Also, a controller is synthesised during this procedure. A numerical example demonstrates the procedure and proves the efficiency of this approach.
