Controls gain

08/18/17

“What is the amplification of a controls system?”

 

When a signal passes through a transfer function, its output will be modified in an according way depending on its frequency. So what do we call the change of magnitude of the signal? Well, after much debate, controls researchers have settled on the idea of gain to describe this. Gain is defined as the ratio of the new magnitude to the old magnitude, such that a system that is twice as large will have a magnitude of 2 and half the size would be 1/2
