Numerical Solution to Parameter Control Inverse Problems in Fluid Mechanics Using Cybernetics Method

The cybernetics method for solving parameter-control inverse problems of engineering fluid m,chanics is presented in the paper.Considering that from the point of view of controlling a system,the inverse problem is identical with cybernetics, it is pointed out that bringing the inverse problem into cybernetics and looking for a combination of one another,a new way for solving inverse problem can be found.The inverse problems of engineering fluid mechanics governed by partial differential equations are taken into account, and recasted as optimal control problems of distributed parameter systems.The inversion of seepage coefficient of underground water in engineering fluid mechanics is taken as an example, and the computer aided optimization method is applied.The numerical results show that the method is suitable for solving parameter control inverse problems.
