Study on optimal control of air pollution using adjoint equation
用伴随方程研究空气污染的优化控制

Based on a set of problems on the optimal control of air pollution, the adjoint equation of the transport diffusion equation for three dimensional, uneven terrain was derived. Based on the relationships between the adjoint equation and its original equation, the problems of optimization could be transformed, equivalently. After the transformation, the number of calculations coule be largely reduced. It was indicated that the prediction is a direct problem and is to be solved with the original equation in the direct way. On the other hand, the optimal control is a reverse problem and is to be solved with the adjoint equation.
