Bounded-error identification for closed-loop systems
This paper presents a scheme for the identification of a system which operates in closed-loop and in the presence of bounded output disturbances. Two algorithms are proposed to solve this identification problem. The first algorithm is an Optimal Bounding Ellipsoid (OBE) type algorithm. This first algorithm is analyzed and sufficient conditions for stability and convergence are established. Rela...
متن کاملClosed loop output error identification with bounded disturbances
The problem of closed loop system identification in presence of bounded disturbances is considered. In this paper two recursive algorithms are proposed to solve this identification problem. Stability and convergence properties are demonstrated. Simulation results validate the proposed solutions.
متن کاملClosed Loop Identification of Nonlinear Systems 1
In recent years, several new methods for the identiication of approximate models of an open loop plant on the basis of closed loop data have been presented. In this paper, we extend two of these methods to the nonlinear case: we consider that both the plant and the controller can be nonlinear. The rst method is a two-step procedure. The sensitivity function of the closed loop system is identiie...
متن کاملA virtual closed loop method for closed loop identification
Indirect methods for identification of linear plant models on the basis of closed-loop data are based on the use of (reconstructed) input signals that are uncorrelated with the noise. This generally requires exact (linear) controller knowledge. On the other hand, direct identification requires exact plant and noise modelling (system in the model set) in order to achieve accurate results, althou...
متن کاملPrediction Error Vs Subspace Methods in Closed Loop Identification
In this paper we investigate the role of the predictor in subspace identification. We shall see that it is the key object which allows to construct realization procedures which ideally work regardless of the presence of feedback. We discuss this point in some detail.
