A new scheme is proposed for the speed control of hydro turbines. Power can be controlled by controlling the rotary motion of the spear valve or linear motion of the sluice gate. In this paper, necessity for speed control, various function of governors, types, speed regulation of...

The production control, via hedging point policies, of a single part type manufacturing system with stochastic capacity and demand is discussed. In the present paper, several feasible operational modes may correspond to equal hedging points. For such generalized hedging point policies, we...
