General parametric and periodic uncertainties and time delay robust control design toolbox

Abstract

The paper presents the Robust Control Toolbox for Time Delay Systems with Parametric and Periodic Uncertainties for the Matlab system. The toolbox defines controlled plant as general 3rd order system with parametric and periodic uncertainties in numerator and denominator of plant transfer function and uncertain time delay. The uncertain time delay is treated using multiplicative uncertainty, the parametric uncertainty is modelled using general interconnection for the systems with parametric uncertainty in numerator and denominator. The toolbox comprises user-friendly graphical interface empowering intuitive control and the tools for both D-K iteration and algebraic approach. The algebraic approach part implements evolutionary algorithm Differential Migration and pole placement for general 3rd order system with evaluation via structured singular value. © 2018 IEEE.
