In this article we apply simple robust linear control to a synchronous power generator driven by a hydraulic turbine and connected to an infinite bus. The goal is to obtain good performance simultaneously for the terminal voltage and the rotor speed for short circuits and also when abrupt, large and permanent variations occur in the parameters of the infinite bus and transmission line. To achieve the goal we increase considerably the crossover frequencies of the terminal voltage and rotor speed feedback loops by taking into account some physical limitations on the controls. The proposed control - of Quantitative Feedback Theory type - is compared in simulations with a classical linear control and a modern nonlinear one.
