DISCRETE-TIME MODEL TYPE DEVICE FOR CONTROLLING STEAM TEMPERATURE IN BOILER FOR STEAM POWER PLANT

摘要

PURPOSE: To apply a discrete-time model adaptation control system and perform a stable operation in a steam temperature control for a boiler of a steam power plant. ;CONSTITUTION: A control calculation function for generating a control signal for accomplishing a control target and a parameter adjusting function for adjusting parameters of calculation of the control signal are assembled into a dispersion type digital calculation control element and the dispersion type digital calculation control element is added in parallel with a normal steam power plant control item, thereby an entire adaptation control system is formed.;COPYRIGHT: (C)1994,JPO&Japio
