Optimization with Piecewise Affine Cost Functions

This report shows how it is possible to solve the problem of the minimization of an objective function composed by the sum of piece-wise affine functions as a Mixed Integer Linear Programming (MILP) problem. ...

Analysis and Control with Performance of Piecewise Affine and Hybrid Systems

Giancarlo Ferrari Trecate

In this paper we investigate some analysis and control problems with performance for discrete-time hybrid systems in the Piece-Wise Affine form. By using arguments from the dissipativity theory for nonlinear systems, we show that

H_infty

NARX Models: Optimal Parametric Approximation of Nonparametric Estimators

Giancarlo Ferrari Trecate

Bayesian regression, a nonparametric identification technique with several appealing features, can be applied to the identification of NARX (nonlinear ARX) models. However, its computational complexity scales as

O(N^3)

where

N

is the data set size. In ...

Reconfiguration strategies for hybrid systems

Giancarlo Ferrari Trecate

In this work we propose several algorithms to solve the reconfiguration problem for linear and hybrid systems. In particular, we consider the decision about the usage of redundant hardware in order to compensate for faults. While this problem can be transl ...

Mixed Logic Dynamical Model of a Hydroelectric Power Plant

Giancarlo Ferrari Trecate

In this work we present the model of a hydroelectric power plant in the framework of Mixed Logic Dynamical (MLD) systems. Each outflow unit exhibits a hybrid behavior since flaps, gates and turbines are controlled with logical inputs and the outflow dynami ...

A clustering technique for the identification of piecewise affine and hybrid systems

Giancarlo Ferrari Trecate

In this paper we focus on the identification of discrete-time hybrid systems in the Piece-Wise Affine (PWA) form. This problem can be formulated as the reconstruction of a possibly discontinuous PWA map with a multi-dimensional domain. In order to achieve ...

Regularization Networks for Inverse Problems: A state-space approach

Giancarlo Ferrari Trecate

The solution of linear inverse problems obtained by means of regularization theory has the structure of a neural network similar to classical RBF networks. However, the basis functions depend in a nontrivial way on the specific linear operator to be invert ...
