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.
