DESIGN OF CONTROLLERS FOR TIME DELAY SYSTEMS PART II. INTEGRATING AND UNSTABLE SYSTEMS

Petr Dostál - František Gazdoš - Vladimír Bobál

   The paper deals with the design of controllers for integrating and unstable time delay systems. The proposed method is based on the time delay approximation and the polynomial approach. A simple control structure with two feedback controllers is considered. Resulting continuous-time controllers obtained via polynomial equations and the LQ-control technique ensure asymptotic tracking of step references as well as step load disturbances attenuation. Simulation results are presented to illustrate the proposed method.

Keywords: time delay system, time delay approximation, polynomial method, LQ~control
