Hybrid Model Reference Adaptive Control of Piecewise Affine Systems

Many engineering systems (e.g. vibro-impacting machines, power-electronic devices) are governed

by differential equations with switches and discontinuities. Model Reference Adaptive Control (MRAC)

is successfully used in many applications but extension to systems described by switched and hybrid

models remains open problem. Paper presents generic MRAC framework for piecewise-smooth

continuous systems, including rigorous proof-of-convergence based on recent extensions of passivity

theory to switched systems. Co-author Montarano is with Instituto Motori of Italian National Research

Council where control strategy is being applied experimentally on prototype electromechanical throttle

valves in collaboration with various automotive companies including Bosch and Magneti Marelli.
