State detection of the sensors of magnetic bearings

The characteristics of the sensors of magnetic bearings were analyzed. The state of a sensor was classified as three categories: normal, ordinary and abnormal states. A kind of multivalue logic algebra based on sequential variables was presented for the state detection of the multisensors of magnetic bearings. The definition of the algebra was given. A few theorems were proved, which are usually used in deduction. An example was given, which showed that there may be more than one solution for some equations. It was analyzed in detail about the method of the state detection of the sensors of magnetic bearings according to the multivalue logic algebra based on sequential variables.
