Sundstrand Hydro Transmission EDC – Constant Speed Control

When you need more accurate control speed to have more independent motor load, then that is where constant speed control comes into play. The closed loop speed controls can offer you the constant control you want by applying a proportional, derivative and integral closed loop control application to give more motor/pump speed. The feed forward control lessens momentary moments during the pump speed changes. An EDC controls pump displacement.
More recent application of this constant control speed is on a hydrostatic transmission drive for a AC electrical generators. They can be hydro statically driven from the vehicle engine, thus making it so you dont need another generator to drive the engine.
