On a switching control scheme for nonlinear systems with ill-defined relative degree [PDF]
, 2002 This paper discusses the applicability of a switching control scheme for a nonlinear system with ill-defined relative degree. The control scheme switches between exact and approximate input-output linearisation control laws.

Nonlinear Dynamic Model-Based Adaptive Control of a Solenoid-Valve System
Journal of Control Science and Engineering, 2012 In this paper, a nonlinear model-based adaptive control approach is proposed for a solenoid-valve system. The challenge is that solenoids and butterfly valves have uncertainties in multiple parameters in the nonlinear model; various kinds of physical ...

Nonlinear robust hierarchical control for nonlinear uncertainsystems [PDF]
Mathematical Problems in Engineering, 1999 A nonlinear robust control‐system design framework predicated on a hierarchical switching controller architecture parameterized over a set of moving nominal system equilibria is developed. Specifically, using equilibria‐dependent Lyapunov functions, a hierarchical nonlinear robust control strategy is developed that robustly stabilizes a given nonlinear

Nonlinear control synthesis by convex optimization [PDF]
, 2004 A stability criterion for nonlinear systems, recently derived by the third author, can be viewed as a dual to Lyapunov's second theorem. The criterion is stated in terms of a function which can be interpreted as the stationary density of a substance that

Linear predictors for nonlinear dynamical systems: Koopman operator meets model predictive control [PDF]
at - Automatisierungstechnik, 2016 This paper presents a class of linear predictors for nonlinear controlled dynamical systems. The basic idea is to lift (or embed) the nonlinear dynamics into a higher dimensional space where its evolution is approximately linear.
