Disturbance attenuation and H/sub infinity /-control via measurement feedback in nonlinear systems
TL;DR: In this article, a solution to the problem of disturbance attenuation via measurement feedback with internal stability is presented for an affine nonlinear system, in which the concept of truncated L/sub 2/ norms can be given an interpretation in terms of the response to periodic inputs in the sense of RMS amplitude, even in the nonlinear setup.

TL;DR: In this article, the authors provide a detailed treatment of the design of robust adaptive controllers for nonlinear systems with uncertainties, based on the ideas of system immersion and manifold invariance.

Immersion and invariance: a new tool for stabilization and adaptive control of nonlinear systems
Alessandro Astolfi,Romeo Ortega +1 more
TL;DR: It is shown that in adaptive control problems the method yields stabilizing schemes that counter the effect of the uncertain parameters adopting a robustness perspective, and the proposed approach is directly applicable to systems in feedback and feedforward form, yielding new stabilizing control laws.

Discontinuous control of nonholonomic systems
TL;DR: In this article, the problem of local asymptotic stabilization for a class of discontinuous nonholonomic control systems via discontinuous control is addressed and solved from a new point of view.

Homogeneous Approximation, Recursive Observer Design, and Output Feedback
TL;DR: A new global asymptotic stabilization result by output feedback for feedback and feedforward systems is proposed by combining a new recursive observer design procedure for a chain of integrator.
