PROBLEM TO BE SOLVED: To solve the problem that, since there are possibilities that a large temperature gradient is generated depending on the loading rate, high stress and uneven thermal expansion are generated, and a turbine clearance is changed during the operation, there is a need to dynamically monitor and predict the turbine clearance condition and the expansion to operate a turbine at the most effective range. SOLUTION: The method for control the turbine clearance includes a step 704 of applying at least one operation parameter as an input to at least one neural network model; a step 706 of modeling the thermal expansion of at least one turbine component through the neural network model; and a step 708 of performing a control task based on at least part of the modeled thermal expansion of one or more turbine components.
