Research on the Control Strategy of Hydraulic Turbine Generating Units Based on Improved FNNC

Because hydraulic turbine generating units system is a complicated non-linear MIMO system, it is difficult to gain better control performance using tradition control strategy to control it. The improved fuzzy neural network controller is presented to control hydraulic turbine generating units. The learning method of network is improved according to the existent problem of fuzzy neural network in on-line learning. The designed fuzzy neural network controller can make reasoning on-line based on fuzzy reasoning system. In training, fuzzy reasoning rules, member function and parameters can be trained on-line through neural network. Simulation experiment results show that the designed improved fuzzy neural network controller may control hydraulic turbine generating units efficaciously and has quick controlling speed and less controlling max-error. So it provides a good control strategy for hydraulic turbine generating units system.
