This paper deals with controlling and simulating ofsuperheated steam temperature system using dual loop controlconcept. Super heaters are heat exchangers that transfer energyfrom flue gas to superheated steam and are important units ofthermal power plant. In industries PID has a wide range ofapplications. Conventional control of thermal power plant superheaters by using PID controller is known to be efficient. Dualloop PID control is used for two stage attemperation to controlthe temperature of superheated steam. There is a high nonlinearity and time delay due to complex and enormous structureof thermal power plant which cannot be compensated easily. So,cascade PID control is extended with an additional functionblock “Disturbance determination”. It is shown that the controlperformance is greatly improved after addition of this block, byusing MATLAB-SIMULINK software. And the results arediscussed.
