Model validation: a connection between robust control and identification

TLDR
The model validation problem addressed is: given experimental data and a model with both additive noise and norm-bounded perturbations, is it possible that the model could produce the observed input-output data?
Abstract
The gap between the models used in control synthesis and those obtained from identification experiments is considered by investigating the connection between uncertain models and data. The model validation problem addressed is: given experimental data and a model with both additive noise and norm-bounded perturbations, is it possible that the model could produce the observed input-output data? This problem is studied for the standard H/sub infinity // mu framework models. A necessary condition for such a model to describe an experimental datum is obtained. For a large class of models in the robust control framework, this condition is computable as the solution of a quadratic optimization problem. >

Safe Inputs Approximation for Black-Box Systems

TL;DR: This paper proposes a method to under-approximate the set of safe inputs that lead the black-box system to respect a given safety specification, which falls within the framework of probably approximately correct (PAC) learning.

Probabilistic model validation problems with H/sub /spl infin// type uncertainties

TL;DR: In this article, a mixed deterministic/probabilistic model validation problem is investigated, which consists in an additive uncertain model with uncertainty characterized by the H/sub /spl infin// norm, and time-domain experimental data corrupted by a Gaussian noise sequence.

Experimental validation of a truck roll model using asynchronous measurements with low signal-to-noise ratios

TL;DR: In this paper, a 4-DOF roll model was used to evaluate the front dynamics of a tractor semi-trailer system (heavy-duty truck), which is confronted with a large set of measurement data obtained from various experimental driving tests.

Analysis of feedback systems with structured uncertainties

TL;DR: In this article, a general approach for analysing linear systems with structured uncertainty based on a new generalised spectral theory for matrices is introduced, which naturally extend techniques based on singular values and eliminate their most serious difficulties.

Structured uncertainty in control system design

TL;DR: This paper reviews control system analysis and synthesis techniques for robust performance with structured uncertainty in the form of multiple unstructured perturbations and parameter variations in the case where parameter variations are known to be real.

Control oriented system identification: a worst-case/deterministic approach in H/sub infinity /

TL;DR: The authors formulate and solve two related control-oriented system identification problems for stable linear shift-invariant distributed parameter plants, each involving identification of a point sample of the plant frequency response from a noisy, finite, output time series obtained in response to an applied sinusoidal input.
