Claim 12:
13. A control method, comprising:
using a controller for acquiring a current control amount of an operation machine as new input data and outputting new output data with respect to the new input data to control the operation machine;
acquiring attribute information comprising statistics of previously obtained input data and the output data;
comparing the new input data with the statistic of the previously obtained input data to obtain a first comparison result and comparing the new output data with the statistic of the previously obtained output data to obtain a second comparison result;
evaluating, based on at least one of the first comparison result and the second comparison result, to what extent at least one of the new input data and the new output data deviates from the statistics;
using the new output data output from the controller to control the operation machine in response to evaluating that the new input data and the new output data do not deviate from the statistics; and
using an auxiliary controller different from the controller without using the new output data to control the operation machine in response to evaluating that the new input data and the new output data deviate from the statistics.
