A Steam - Boiler Control

Application of Fuzzy Strategy in the Superheated Steam Temperature Control System of Boiler

Abstract. By testing the superheated steam temperature and its variation trend ,the traditional superheated steam temperature control system of boiler regulates desuperheating water flow so as to control the superheated steam temperature within permitted range . Under the influence of disturbance in desuperheating water flow, the delay of superheated steam temperature is bigger,which makes supe...

Application of Neuro-predictive Approach for Disturbance Rejection in a Steam Drum Boiler

In this paper a neuro-predictive method is proposed in order to control the water level in the steam drum boiler system being in use at a Power Plant of Iaşi, Romania. The steam boiler provides thermal and electrical power and it works under complex technology in order to satisfy numerous technical, security and economical requirements. A nonlinear dynamic simulator for the proposed steam drum ...

Cascade control of superheated steam temperature with neuro-PID controller.

In this paper, an improved cascade control methodology for superheated processes is developed, in which the primary PID controller is implemented by neural networks trained by minimizing error entropy criterion. The entropy of the tracking error can be estimated recursively by utilizing receding horizon window technique. The measurable disturbances in superheated processes are input to the neur...

Inverse Dynamic Neuro-Controller for Superheater Steam Temperature Control of a Large-Scale Ultra-Supercritical (USC) Boiler Unit

The main focus of this paper is to develop an Inverse Dynamic Neuro-Controller (IDNC) by utilizing the inverse dynamic relationship of the superheater system for a large-scale ultra-supercritical (USC) boiler unit. After a recurrent neural network-based Inverse Dynamic Process Model (IDPM) has been built and trained, it is then used as a feedforward controller to improve the superheater steam t...
