Deep learning with transfer functions: new applications in system identification

Autor: Dario Piga, Marco Forgione, Manas Mejari

Publikováno v: IFAC-Papers

This paper presents a linear dynamical operator described in terms of a rational transfer function, endowed with a well-defined and efficient back-propagation behavior for automatic derivatives computation. The operator enables end-to-end training of

An integral architecture for identification of continuous-time state-space LPV models

Autor: Manas Mejari, Bojan Mavkov, Dario Piga, Marco Forgione

Publikováno v: IFAC-PapersOnLine. 54:7-12

This paper presents an integral architecture for direct identification of continuous-time linear parameter-varying (LPV) state-space models. The main building block of the proposed architecture consist of an LPV model followed by an integral block, w

Recursive Bias-Correction Method for Identification of Piecewise Affine Output-Error Models

Autor: Valentina Breschi, Dario Piga, Manas Mejari

Publikováno v: IEEE Control Systems Letters. 4:970-975

Learning PieceWise Affine Output-Error (PWA-OE) models from data requires to estimate a finite set of affine output-error sub-models as well as a partition of the regressors space over which the sub-models are defined. For an output-error type noise

A Bias-Correction Approach for the Identification of Piecewise Affine Output-Error Models

Autor: Manas Mejari, Dario Piga, Vihangkumar V. Naik, Valentina Breschi

Publikováno v: IFAC-PapersOnLine. 53:1096-1101

The paper presents an algorithm for the identification of PieceWise Affine Output-Error (PWA-OE) models, which involves the estimation of the parameters defining affine submodels as well as a partition of the regressor space. For the estimation of af

Maximum—A Posteriori Estimation of Linear Time-Invariant State-Space Models via Efficient Monte-Carlo Sampling

Autor: Manas Mejari, Dario Piga

Publikováno v: ASME Letters in Dynamic Systems and Control. 2

This article addresses maximum-a-posteriori (MAP) estimation of linear time-invariant state-space (LTI-SS) models. The joint posterior distribution of the model matrices and the unknown state sequence is approximated by using Rao-Blackwellized Monte-

Shrinkage Strategies for Structure Selection and Identification of Piecewise Affine Models

Autor: Manas Mejari, Valentina Breschi

Publikováno v: CDC

We propose two optimization-based heuristics for structure selection and identification of PieceWise Affine (PWA) models with exogenous inputs. The first method determines the number of affine sub-models assuming known model order of the sub-models,

Computation of Parameter Dependent Robust Invariant Sets for LPV Models with Guaranteed Performance

Autor: Ankit Gupta, Manas Mejari, Paolo Falcone, Dario Piga

This paper presents an iterative algorithm to compute a Robust Control Invariant (RCI) set, along with an invariance-inducing control law, for Linear Parameter-Varying (LPV) systems. As the real-time measurements of the scheduling parameters are typi
