Abstract :
The synthesis of a viable control strategy for the multiple-jet impulse turbines utilized in the Bradley Lake hydroelectric project in Alaska is discussed. Digital simulation is used to assess modifications to various control schemes. Control is locally stable, but unstable to large perturbations. A strategy is developed which achieves global stability of the system. The new control is primarily based on enhancing deflector contributions to control
