Hybrid Modeling and Control of a Hydroelectric Power Plant

Giancarlo Ferrari Trecate

In this work we present the model of a hydroelectric power plant in the framework of Mixed Logic Dynamical (MLD) systems. Each outflow unit exhibits a hybrid behaviour since flaps, gates and turbines are controlled with logical inputs and the outflow dynam ...
