中文摘要：

热泵系统实际运行过程中其状态总是时刻动态变化，为了保证实时COP的优化和安全运行，水源热泵系统的节能运行问题逐渐成为热泵领域的一个研究热点；由于水源热泵系统的动态数学模型为非线性的，因此节能运行问题为非线性最优控制问题，在系统的机理建模、节能运行最优控制问题构造及求解方面都面临较多理论难点。本文对如何应用最优控制理论、鲁棒控制理论解决水源热泵系统节能运行控制问题做了初步探讨。

英文摘要：

The optimal economical control problem（OEC） of WSHP is receiving considerable attention lately to guarantee dynamic COP and stability indices of system operation. Because the OEC problem is a nonlinear optimal control problem and complicated to solve, no analytical OEC strateges based on WSI-IP nonlinear mathematical model are obtained. The study achievements in economical operation of WSHP was summarized, and the mathod how to solve the economical operation problem of WSHP was discussed by adopting advanced optimal control theory and robust control theory.
