Abstract

PURPOSE:To perform a combinational test almost on actual plant condition with high precision and high efficiency by deciding a process signal as to whether information is adequate for a simulator model or not, and calculating and feeding dynamic characteristics of a plant back to a control module. CONSTITUTION:A computer internal processing switch 11 connects contacts (a) and (b) to each other to connect a control module 6 to an input/output part 5, and the process signal 12 from the module 6 is inputted to an analytic judgement part 4 through the input/output part 5. Further, the process signal 12 is sent to a model description part 3 and the model in the description part 3 calculates dynamic characteristics of the plant on the basis of the signal 12 and converts them into a process information value 10, which is outputted to the judgement part 4. The judgment part 4 checks whether the information value 10 is adequate or not and sends the information value 10 to the module 6 through the input/ output part 5. The module 6 converts the information value 10 into a display request signal 13, which is sent to a CRT9 to offer an operator the necessary information value through an incorporated simulator as well as the actual plant 8.
