A cascade control was used to control the superheated steam temperature of a 600MW unit in a power plant
having very big time-delay. It has been retrofitted by using a control mode of fuzzy control combined with PI control. The fuzzy control has good effect to the regulated paramenter even at the time in which only very small operating condition flucturation being occurred
and the integral effect of PI control can effectively eliminate the static error. The debugging result after retrofitting shows
the main steam temperature can be controlled in a range of 530℃~545℃ under various operating conditions
