Real time control of reservoir systems

The method, called Extended Linear Quadratic Gaussian (ELQG) controller, draws on and extends stochastic control theory results, and is well suited for the optimization of constrained dynamical systems. ELQG is a trajectory iteration algorithm theoretically expected to exhibit reliability and computational efficiency. ELQG was used in case studies of two reservoir systems located in the River Nile Basin. The results indicate that ELQG"s theoretical properties are indeed realized in practice and that the method has distinct advantages over state-of-the-art procedures. The success of ELQG opens a host of further research directions. (Author abstract, modified)
