✦ Synopsis

For monitoring of a superconducting magnet, we have proposed a new method using Fuzzy theorem. This method utilizes a number of detectable items, such as transport current, terminal voltage, strain, AE, etc. as fundamental membership functions. We have investigated about the relation between the number of membership functions and the state of superconducting magnet. A tentative investigation has been carried out on a superconducting magnet called "TOKI-MC" module coil at NIFS. The result shows that the obtained "dangerous rate" can well explain the state of the magnet. And it becomes clear that at least 4 to 6 membership functions are necessary for diagnosis of the superconducting magnet.
