WebOpen-loop bode plot The main idea of frequency based design is to use the Bode plot of the open-loop transfer function to estimate the closed-loop response. Adding a controller to the system changes the open-loop Bode plot, therefore changing the closed-loop response.

Putting aside the fact that a system with a single complex or imaginary pole is unrealizable, if you have a control loop whose open-loop gain is. H o ( s) = k s + j ω, and then you close the loop, you will get a system whose closed-loop gain is. christmas planter box ideas
