Droop speed control - Wikipedia

Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid.It works by controlling the rate of power produced by the prime mover according to the grid ...

Jul 22, 2015· Velocity is derived from change of position, so there is no way to change that. There is no true "Velocity" from your master external encoder. I'm trying to understand your application. Normally, if you are synchronized, then your follower will always try to follow the master, even if it rotates backwards. That is why it is called synchronization.
