Abstract.  A mathematical model describing the operation of the cross-flow water turbine has been developed in this paper. A robust governor has been synthesized using H∞ techniques to replace the conventional governor of the water turbine . The transient processes in the system are compared to the processes where the classical PID controller is used. The simulations are carried out using MATLAB and the results show that the overall system output performance can be improved using the proposed H∞ robust governor.
