Idealized Feedback Design
Open loop (controller and plant) and plant-only Bode plots for the Scaling a Fixed-Point Control Design demo are shown below. The open loop Bode plot results from a digital controller described in the idealized world of continuous time, and double precision coefficients, storage of states, and math operations.
The plant and controller design criteria are not important for the purposes of this tutorial. The Bode plots were created using the workspace variables produced by the preload_feedback M-file.
