PURPOSE:To dynamically decide or correct the landmark of qualitative and quantative space required at the time of converting a detection value obtained from an image forming device to a qualitative value in accordance with the condition of the image forming device. CONSTITUTION:A pseudo fault occurrence part 14 operates actuator controllers 2C, 3C, and 5C, and forcibly causes a fault on the image forming device. And the part 14 reads the detection value of sensors X, VS, and DS at the time of forcibly causing the fault, and corrects a membership function as the landmark stored in a membership function forming part 13 based on the detection value read and the detection value which is obtained from the sensors X, VS, and DS before the fault is caused. Then, the detection value of the sensors X, VS, and DS is converted to a fuzzy qualitative value based on the membership function corrected, and is submitted for control thereafter. |
