<p>PURPOSE:To shorten the time required for a calculation by executing a difference approximate calculation by an approximate rational Runge-Kutta method by the sum of the product of a variable coefficient which is varied in accordance with increase and decrease of a differential coefficient, and a variation which is forecast from the fine coefficient. CONSTITUTION:A plant simulation device is constituted of a computer 1 for calculating a dynamic characteristic equation of a simulation object by a difference approximate calculation, a display device 2 for displaying a result of calculation by this computer 1, and an operating device 3 for operating the display device 2 and the computer 1. The difference approximate calculation of the dynamic characteristic equation by the computer 1 is executed approximately by the sum of the product of a variation which is forecast from a differential coefficient in plural points in a prescribed time interval of the dynamic characteristic equation, and a variable coefficient which is varied in accordance with increase and decrease of this variation.</p> |
