This paper deals with fuzzy control of state variables in an interconnected multi-reservoir power system combined with real-time prediction. A mathematical model of the system in described as a discrete-time stochastic state-space model, including conditions which restrict the amount of water released from the upper stream reservoir and also restrict the method of discharging the water into the lower stream. In practice, it is required to notify few hours in advance the change of discharge into the lower stream. This is the reason why we need real-time prediction of the states for determining the amount of control well in advance. As the results of simulation studies we point out the effectiveness of fuzzy control compared with optimal regulator from the point of view of practical control of extending the durability of water gates and power generators.
