Nonlinear sliding mode high-gain observers for fault estimation
A robust high gain observer for state and unknown inputs/faults estimations for a special class of nonlinear systems is developed in this article. Ensuring the observability of the faults/unknown inputs with respect to the outputs, the faults can be estimated from the sliding surface. Under a Lipschitz condition for the nonlinear part, the high gain observers are designed under some regularity ...
متن کاملIncreasing-gain observers for nonlinear systems: Stability and design
For the purpose to estimate the state of nonlinear continuous-time systems, we focus on the increasing-gain observer regarded as generalization of the well-known high-gain observer. As compared with the previous results on increasing-gain observers, the assumptions under which the global asymptotic stability of the estimation error is proved are relaxed. The stability analysis is drawn by using...
متن کاملA hybrid scheme for reducing peaking in high-gain observers for a class of nonlinear systems
For a family of nonlinearly interconnected second order plants, we propose a hybrid modification of the well known high-gain observer design, which leads to guaranteed asymptotic stability properties of the error dynamics, as well as exhibiting significantly reduced peaking. The hybrid modification results in suitable jumps of the observer state, which therefore corresponds to a discontinuous f...
متن کاملOn Output Feedback Nonlinear Model Predictive Control Using High Gain Observers for a Class of Systems
In recent years, nonlinear model predictive control schemes have been derived that guarantee stability of the closed loop under the assumption of full state information. However, only limited advances have been made with respect to output feedback in connection to nonlinear predictive control. Most of the existing approaches for output feedback nonlinear model predictive control do only guarant...
متن کاملHigh gain observers with updated gain and homogeneous correction terms
Exploiting dynamic scaling and homogeneity in the bi-limit, we developp a new class of high gain observers which incorporate a gain update law and nonlinear output error injection terms. A broader class of systems can be addressed and the observer gain is better fitted to the incremental rate of the nonlinearities. The expected improved performance is illustrated.
