Hi,

I'm a bit confused about the load disturbance sensitivity function in control loops. Basically, I have a design where the load disturbance sensitivity function has a maximum of 5 at a frequency of 300 Hz.

I'm not sure I understand this metric correctly. Does it mean that a load variation of 10% at a frequency of 300 Hz would create a variation 5 times higher on the output?

The formula is P/(1+PC) where P is the transfer function of the process and C the transfer function of the controller

Regards
