A lemma of Razumikhin type, pertaining to boundedness of solutions of functional differential equations, is presented. This lemma is subsequently invoked in the analysis of adaptive strategies that...
Robust State Feedback Control of LTV Systems: Nonlinear Is Better Than Linear (1999)
Examples of linear control systems with fast time-varying uncertain coefficients are given, which can be stabilized by a nonlinear memoryless state feedback, but cannot be stabilized by a linear time...
