The forced-circulation evaporator is a multi-input multi-output nonlinear process which has complex dynamics characteristics, such as strong coupling, serious nonlinearity and parameter uncertainty. As a result, the conventional control strategy can not achieve satisfactory control performance. A nonlinear adaptive decoupling control strategy is proposed in this paper. The control strategy combines...
A compensator is proposed to achieve globally and practically adaptive output tracking control for a class of linearly parameterized nonlinear systems with uncontrollable unstable linearization under the framework Immersion and Invariance (I&I) tool. As illustrated in [9], the globally asymptotic output tracking of a time-varying reference signal for this class of nonlinear systems is usually...
In this paper, a global robust stabilizer for a class of uncertain non-minimum-phase nonlinear systems in generalized output feedback canonical form is designed. The system contains unknown parameters multiplied by output-dependent nonlinearities and output-dependent nonlinearities enter such a system both additively and multiplicatively. The proposed method relies on a novel parameter estimator and...
In this paper, a new global adaptive output feedback dynamic compensator is proposed for tracking of a class of systems that are globally diffeomorphic into systems in generalized output feedback canonical form. Output-dependent nonlinearities are allowed to enter in both cases as additive and multiplicative. The system is allowed to contain unknown parameters multiplying output-dependent nonlinearities...
