Abstract

The paper discusses the measurement of a controller robustness for given uncertainties in plant parameters for an LTI and SISO model. Robustness is calculated according to some regions of z-plane or s-plane where the closed-loop system poles must be delimited. The method employs a geometric representation of the uncertainty space in the system parameters and is based on algebraic relationships characteristic of R ^N vector spaces; thus, a calculation environment like MatLab is very suitable for its implementation
