This paper concerns the experimental evaluation of a PID mixed H2/H∞ control methodology based on the application of genetic algorithms. The considered plant is an experimental DC servosystem affected by disturbances acting on its output, and the performance objective corresponds to the control of the load angular position.
We present here a study concerning the Geometrie Characterization of Feedback Control Laws for Linear Time Invariant Systems. Both Computer Algebra and Numerical approaches are considered. The Disturbance Decouplong Problem is taken as a Case of Study.
Low‐molecular weight cyclic alcohols as cycloheptanol (C7H14O, hereinafter referred to as cC7‐ol) and cyclooctanol (C8H16O, cC8‐ol) are prototypical materials displaying OD phases which, under fast cooling give rise to orientational glasses (OG). In addition to the ubiquitous α‐relaxation of canonical glasses, several secondary relaxations appear for the mentioned systems (β and γ for cC8‐ol and β...
