Local Separation Principle for a Special Class of Nonlinear Systems
نویسندگان
چکیده
In this paper, we establish the local separation principle for the class of nonlinear systems which is approximately error linearizable and locally asymptotically stabilizable. For this class of nonlinear systems, it is first shown that there exists a local nonlinear observer whose estimation error converges to zero exponentially. In order to achieve local output feedback stabilization, the proposed nonlinear observer is employed in conjunction with the locally asymptotically stabilizing controller. As a result, we identify the class of nonlinear systems for which the local separation principle holds.

Output Feedback Nonlinear Predictive Control -a Separation Principle Approach
Over the recent years many advances in the area of nonlinear model predictive control have been made. However, with respect to the output feedback problem and predictive control only a limited number of results are available. Most of the existing approaches do only guarantee local stability. In this note we propose the use of a high gain observer in combination with a sampled nonlinear predicti...
متن کاملSeparation Principle for a Class of Nonlinear Feedback Systems Augmented with Observers
The paper suggests conditions for presence of quadratic Lyapunov functions for nonlinear observer based feedback systems with an ’input nonlinearity’ in the feedback path. Provided that the system using state feedback satisfies the circle criterion (i.e., when all states can be measured), we show that stability of the extended system with output feedback control from a (full state) Luenberger-t...
متن کاملRobust Model Predictive Control for a Class of Discrete Nonlinear systems
This paper presents a robust model predictive control scheme for a class of discrete-time nonlinear systems subject to state and input constraints. Each subsystem is composed of a nominal LTI part and an additive uncertain non-linear time-varying function which satisfies a quadratic constraint. Using the dual-mode MPC stability theory, a sufficient condition is constructed for synthesizing the ...
متن کاملLocal stabilization for a class of nonlinear impulsive switched system with non-vanishing uncertainties under a norm-bounded control input
Stability and stabilization of impulsive switched system have been considered in recent decades, but there are some issues that are not yet fully addressed such as actuator saturation. This paper deals with expo-nential stabilization for a class of nonlinear impulsive switched systems with different types of non-vanishing uncertainties under the norm-bounded control input. Due to the constraine...
متن کاملADAPTIVE FUZZY TRACKING CONTROL FOR A CLASS OF PERTURBED NONLINEARLY PARAMETERIZED SYSTEMS USING MINIMAL LEARNING PARAMETERS ALGORITHM
In this paper, an adaptive fuzzy tracking control approach is proposed for a class of single-inputsingle-output (SISO) nonlinear systems in which the unknown continuous functions may be nonlinearlyparameterized. During the controller design procedure, the fuzzy logic systems (FLS) in Mamdani type are applied to approximate the unknown continuous functions, and then, based on the minimal learnin...
