摘要：

An approximate analytical solution to the problem of determining the optimal flow rate through solar collectors so as to maximize the integral of the difference between the useful energy and the pumping costs incurred in collecting the solar energy has been obtained. The solution that is presented is an optimal feedback controller that is based upon measurable states of the system. The solution technique that was employed was that of the Pontryagin maximum principle and an approximate analytical solution to the resulting two-point boundary value problem was obtained by means of a transformation that involved using the heat removal factor as the control. The optimal control (the mass flow rate) is then recoverable from the heat removal factor. The derivation of the optimal control law is presented. Also presented is a discussion of implementation of the optimal control law. Finally, comparisons between these results and those presented in an earlier paper in which a numerical solution was obtained are presented. © 1979.
