## Content(s)

ROBUST CONTROL COURSE

Introduction
Industrial examples (automotive and electromechanical applications).
1 Tools
Hinf norm, Small Gain theorem
Introduction to LMIs (definition, use of LMIs for stability analysis and control design)
2 Performance analysis
MIMO sensitivity functions, frequency-domain performance indices (sensitivity functions, stability and robustness margins, bandwidth, SISO and MIMO cases)
3 Hinf control design
Performance Specifications (selection of weighting functions, Mixed sensitivity problem)
Solving the Hinf control problem: General control conguration, Hinf controller structure (state feedback, dynamic output feedback), Problem solution using Riccati equations or LMIs -Bounded Real Lemma)
4 Linear Parameter Varying systems
Definition, stability issue, observer and control design
5 Uncertainty and robustness
Modelling the uncertainties (unmodelled dynamics, unstructured uncertainties, structured uncertainties, LFT representation)
Robust stability analysis (small gain theorem - unstructured uncertainties)
Robust performance analysis
mu-analysis - structured uncertainties

Modelisation, simulation and conception of mechatronic systems. Industrial and mobile robotics notions. Specification and evaluation of dynamical performances. Embedded control systems and reference generation. Disturbance estimation and adaptive rejection of disturbances. Fault-tolerant control notions. Code implementation in microprocessors.
