Abstract

A boiler drum and heat exchanger QAD Model BDT921 that is installed in the Control Laboratory is being used as a model plant to achieve the digital control system design since it is analog in nature. The digital control design need a mathematical model of the system is designed. This paper covers a discrete time model of boiler drum and heat exchanger QAD Model BDT 921. The model is obtained from parameter gain values of the real system and then this model will simulate using MATLAB program. The proportional integral differential (PID) controllers are being chosen as the control element in discrete form as the real system is using the same control element. The output responses behave as the second order system with a closed correlation in rise times and peak times compared with data obtained from experiment and simulation results. With regarding to the analysis done, the digital control can be implemented to the boiler drum and heat exchanger control system and for further viewing, to be controlled digitally with computer in the control room. 1
