On asymptotic properties of MOESP-type closed-loop subspace model identification
Recently, MOESP-type closed-loop subspace model identification (CL-MOESP) has been proposed by the authors and its effectiveness has been demonstrated via both numerical simulations and real-life systems, e.g., a cart-inverted pendulum system. However, asymptotic properties of CLMOESP has not yet been studied. The purpose of this paper is to clarify the asymptotic properties of CL-MOESP from th...
متن کاملRecursive MOESP Type Subspace Identification Algorithm
In this paper two recursive algorithms, based on MOESP type subspace identification, are presented in two versions. The main idea was to show that we can represent subspace identification methods as sequences of least squares problems and implement them through sequences of modified Householder algorithms. Therefore, it is possible to develop iterative algorithms with most of the advantages of ...
متن کاملSubspace closed loop identification using the integration of MOESP and N4SID methods
Linear identification of time invariant systems operating in closed loop is of special interest for a large number of engineering applications. There are different techniques and methods to carry out this type of identification. For example, modifying the N4SID method, one can derive a closed loop subspace identification method. The same can be done using the MOESP method. Based on them, the MO...
متن کاملSubspace-based optimal IV method for closed-loop system identification
This paper deals with an optimal instrumental variable method dedicated to subspace-based closed-loop system identification. The presented solution is based on the MOESP technique but requires to modify the original scheme by proposing a new PO MOESP method which uses reconstructed past input and past output data as instrumental variables. The developed approach is then illustrated via a simula...
متن کاملSubspace identification from closed loop data
So called subspace methods for direct identiication of linear models in state space form have drawn considerable interest recently. They have been found to work well in many cases but have one drawback { they do not yield consistent estimates for data collected under output feedback. This contribution points to the reasons for this and also shows how to modify the basic algorithm to handle clos...
