Abstract
There are typically two main control loops with PI controllers operating at each turbo-generator set. In this paper a model predictive controller QDMC for the steam turbine is proposed - instead of a typical PI controller. The QDMC controller utilize a step-response model for the controlled system. This model parameters are determined, based on the simplified and linear model of turbo-generator set, which parameters are identified on-line with RLS algorithm. It has been found that the proposed QDMC controller realize the reference trajectories of the effective power and the angular velocity, and damp the electromechanical oscillations with satisfactory quality in comparison to the typical PI and DMC controllers.
