eng	Estimation of Parameters of a Model of a Steam Overheater from Service Data	The paper describes a procedure of obtaining estimated values of parameters of a model of a controlled powerplant steam overheater from measured service data. The overheater consists of two subsystems that can be identified separately - cooling steam by water injection and heating steam part. Statistical estimation of parameters from measured data is complicated by the fact that the disturbances influencing the outlet temperature are not pure random. Moreover, since the plant is under feedback, correlation between the disturbances and the system input has to be considered.	heat systems;mathematical modeling;system identification;control systems
