Abstract :
Proposes a methodology for the analysis of the stability in a 2 DOF dead-time compensator when controlling integrative processes. The study considers the effects of the dead-time uncertainties and the actuator saturation on the closed-loop stability. The obtained results allow us to define a robust tuning rule for the controller. Some simulation results illustrate the proposed methodology
