1. A method of thermocouple failure detection in power generation turbines comprising:

  • creating redundancy estimates from temperature readings generated by said thermocouples;

    predicting an expected value from each temperature reading;

    comparing said temperature readings and said redundancy estimates with said expected value;

    fusing said redundancy estimates and said expected values to generate a fused thermocouple value;

    and generating a thermocouple confidence by comparing said fused thermocouple value and said temperature readings;

    wherein said predicting of expected values is completed by creating a history of the process.
