This paper is devoted to the robust stabilization and passivity of general uncertain nonlinear systems. It is first proved that the unforced system has a unique local solution with any initial value in some neighborhood of the origin. Some properties of robust passive systems are obtained. Based on these properties, it is verified that under some conditions robust passivity of the uncertain sys...

Nonlinear control problems in turbofan engines are challenging. No single nonlinear controller can achieve desired effects a full flight envelope, but the case of multiple controllers, there exist bumpless transfer between different controllers. To this end, paper presents mechanism for an uncertain switched system based on integral sliding mode (ISMC), and be used speed engines. The is to desc...
