SUPERHEATED STEAM TEMPERATURE CONTROL FOR BOILER USING ADAPTIVE DYNAMIC FEEDFORWARD COMPENSATORS

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...

PID Controller Parameters Tuning Based-on Satisfaction for Superheated Steam Temperature of Power Station Boiler

Proposed the PID controller parameters tuning method based-on New Luus-Jaakola (NLJ) algorithm and satisfaction idea. According to the different requirements of each performance index, designed the satisfaction function with fuzzy constraint attributes, and then determined the comprehensive satisfaction function for PID tuning by NLJ algorithm. Provided the steps of PID controller parameters tu...

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...

Adaptive predictive expert control of superheated steam temperature in a coalfired power plant

This paper describes the application of an adaptive predictive expert (ADEX) control solution to the attemperation process for superheated steam temperature control in the ScottishPower coal-fired power station at Cockenzie near Edinburgh in Scotland. The project comprised two phases, the first of which was a trial to establish the feasibility and potential benefits of ADEX compared with the ex...
