摘要：
This paper describes finite-element analysis of electromagnetic fields and optimization of eddy current densities. First, we derive the state equations by means of the finite-element method. Eddy current densities are represented by derivatives of the state variable x(t). A linear quadratic performance index is introduced so that eddy current densities will track the desired functions. We obtain an optimal control law from the stationary conditions of the performance function. Optimal inputs are expressed by solutions of two differential equations. Finally, we show numerical examples.
