✦ Synopsis

This paper considers the problem of robust disturbance attenuation for a class of systems with both Lipschitz bounded and nonlinear uncertainties. The nonlinear uncertainty is assumed to satisfy a 'matching condition' and bounded by a known nonlinear function. The Lipschitz bounded one could be with any mismatched uncertainties. We develop a Riccati equation approach for designing a state feedback controller such that the so-called L -gain from the exogenous input noise to the state is minimized or guaranteed to be no larger than a prescribed value.

A new robust state-feedback controller is designed to solve the tracking problem of a class of nonlinear uncertain systems. The contributions of our paper are threefold: Firstly, a new robust state-feedback controller with a simple structure is derived. Owing to its simplicity, less computation is n

The problem of quadratic stabilization for a class of nonlinear systems is examined in this paper. By employing a well-known Riccati approach, we develop a technique for designing a state feedback control law which quadratically stabilizes the system for all admissible uncertainties.

In this paper, we apply a discrete-time learning algorithm to a class of discrete-time varying nonlinear systems with a$ne input action and linear output having relative degree one. We investigate the robustness of the algorithm to state disturbance, measurement noise and reinitialization errors. We
