水资源时延控制模型及研究

STUDY ON NONLINEAR WATER RESOURCE TIME-DELAY CONTROL MODELS

水资源系统是由水资源自然分系统和人工分系统合成的复杂大系统 .把设计修建的水资源工程视作安装于自然系统上的一个控制器 ,同时考虑当前状态量与时延量的制约关系 .首次建立了一个由流域、湖泊及引水工程等组成的非线性水资源时延控制数学模型 ,讨论了该类系统的稳定性、最优控制、次优控制等理论 ,最后给出次优控制的数值计算及结果 .

Water resource systems can be regard as a complicated large system composed of the natural subsystems and the artificial subsystems. It takes the designed constructed water resource engineering as a controller installed on natural systems, and accounts for time delay factors. The nonlinear water resource time delay control mathematical mode is first set up by considering that the systems are composed of river basin、lakes and diversion works.Stability,optimal control and suboptimal control of the model are discussed. The computational algorithms and results by analysis are provided. [
