Modelling of Process Control that have Time Delay: Verification of Algorithms Suitable for Process Control Containing Time Delay by Simulation

This paper describes such extension of known DB(n) control algorithm which improve behaviour quality of control processes with time delay, This extension, called eDBd algorithm, was derived by author. It can function even if controller output is limited. The synthesis was derived for control loop with proportional third order behaviour of controlled plant. The algorithm can be generalized for controlled plants with higher order and applied for plants with non-minimal phase, plant with time delay and its combination, as is shown in simulation experiments. For experimental evaluation of the control algorithm in real time, hardware in loop simulation was used. Rather, analogue model of real plant with A/D and D/A converters and PC as a controller.
