摘要： A plant model is constructed with a mathematical procedure known as the Kalman filter. The presumed value or predictive value of a certain parameter of a plant is compared with the actually-measured value of the parameter, and the state transition matrix and drive matrix of the Kalman filter are corrected. When a parameter which is a direct controlled object is difficult of actual measurement, the model is corrected by utilizing another parameter whose actual measurement value is easily obtained. When the plant has a feedback control system based on the proportional-plus-integral control, the gain of the system is corrected in correspondence with the corrections of the elements of the matrices.

摘要： An automatic control system for a thermal power plant comprises a master controller controlling a turbine in response to an externally applied load command signal, and producing a boiler input command signal by correcting the load command signal on the basis of the detected pressure of main steam generated from a boiler, and a water/steam process controller, a fuel process controller, a combustion process controller and a draft process controller to all of which the boiler input command signal is applied from the master controller. The process controllers apply control signals to equipments controlling a water/steam process, a fuel process, a combustion process and a draft process respectively among the terminal actuating equipments of the various parts of the boiler.
