Abstract

POWER TURBINES CONTROL, PART IV: STEAM TURBINE SPEED CONTROL USING 2/2 SECOND-ORDER, I-PD COMPENSATORS AND PD-PI, 2DOF-3 CONTROLLERS COMPARED WITH A PI CONTROLLER

Galal Ali Hassaan*

ABSTRACT

This paper is the fourth in a series of research papers presenting the control of power turbines using compensators and controllers from the second generation of compensators and PID controllers. It handles the control of a steam turbine load speed using 2/2 second order compensator, I-PD compensator, PD-PI controller and, 2DOF-3 compensator with comparison with the use of a PI controller from the first generation of PID controllers. The MATLAB optimization toolbox is used to tune the four compensators/controllers using an ITAE performance index. The step time response of the control systemusing the four proposed controllers is presented and compared with using a PI controller to control the same steam turbine and the time-based characteristics are compared. The comparison reveals the best compensator/controller among the four compensators/controllers depending on a quantitative comparison study.
