Identification for A Non-Smooth Distributed Parameter System and Its Optimality Conditions

The parameter identification problem of the temperature field of the transformer is a piecewise smooth identification problem.Taking the flow velocity as the identification parameter,consider a parameter identification problem of temperature field of the transformer,prove the existence of the optimal parameter and the necessary optimality conditions,and present a theoretical basis for the numerical simulation of temperature field of transformers.
