A Projection Method for Closed - loop Identi cationUrban

چکیده
Technical reports from the Automatic Control group in Linkk oping are available by anonymous ftp at the Abstract A new method for closed-loop identiication that allows tting the model to the data with arbitrary frequency weighting is described and analyzed. Just as the direct method this new method is applicable to systems with arbitrary feedback mechanisms. This is in sharp contrast with other methods, such as the indirect method and the two-stage method, which assume linear feedback. To illustrate the eeect of nonlinear elements in the feedback loop on these closed-loop identiication methods a simulation study is presented.

Properties and Usage of Closed-loop Identiication Methods Properties and Usage of Closed-loop Identiication Methods
System identi cation deals with the construction of mathematical models of dynamical systems using measured data. Closed-loop identi cation is what results when performing the identi cation experiment under output feedback, that is, in closed loop. In this thesis we study a number of closed-loop identi cation methods, both classical and more recently suggested ones. A common feature of the meth...
متن کاملOn the relation between a bias-eliminated least-squares (BELS) and an IV estimator in closed-loop identification
A bias-correction method for closed-loop identi"cation, introduced in the literature as the bias-eliminated least-squares (BELS) method (Zheng & Feng, Automatica 31 (1995) 1019), is shown to be equivalent to a basic instrumental variable estimator applied to a predictor for the closed-loop system. This predictor is a function of the plant parameters and the known controller. Corresponding to th...
متن کاملIdenti cation of normalized coprime plant factors from closed loop
Recently introduced methods of iterative identi cation and control design are directed towards the design of high performing and robust control systems. These methods show the necessity of identifying approximate models from closed loop plant experiments. In this paper a method is proposed to approximately identify normalized coprime plant factors from closed loop data. The fact that normalized...
متن کاملClosed-loop Identification with an Unstable or Nonminimum Phase
In many practical cases, the identi cation of a system is done using data measured on the plant in closed loop with some controller. In this paper, we show that the internal stability of the resulting model, in closed loop with the same controller, cannot always be guaranteed if this controller is unstable and/or nonminimum phase, and that the direct, indirect and joint input-output approaches ...
متن کاملClosed-loop Subspace System Identiication 1
In this paper we present a general framework for closed-loop subspace system identi cation. This framework consists of two new projection theorems which allow the extraction of nonsteady state Kalman lter states and of system related matrices directly from closed-loop input output data. Three algorithms for the identi cation of the state space matrices are then presented. The similarities betwe...
