Abstract
PURPOSE: To ensure a smooth switching of control, by setting the outputs of the 1st and 2nd controllers having the target value varying in terms of time plus a fixed target value to the sum of the outputs obtained by multiplying the weight coefficients which are added up to 1.
CONSTITUTION: The controller 26 obtains the control signal from the deviation between the target value TMSR of main steam temperature and the actual measurements TMSA; and the controller 27 obtaines the control signal from the deviation between the value TMSR and the rated value TMSO of main steam temperature, respectively. The comparator 24 blocks the input to be applied to the controller 27 by the multiplier 28B until the value TMSA gets close to the value TMSO. The output of the operator 31 is set to 0 at first. When the value TMSA exceeds a fixed value, the controllers 26 and 27 start a parallel operation. Then the sum of the outputs obtained through a multiplication of the weight coefficients (1-X) and X is delivered 33 in the form of the control signal 29. At the same time, the X is set to vary gradually 0W1. Thus a smooth switching is given to the control of the contoller 27 after a fixed time.
