Single-Loop System Block Diagram

Designing a single-loop system is a straight forward process, where the GUI will represent the power supply in three main blocks: the Plant, the Feedback, and the Compensator. You must define each of the blocks and enter the information required by the GUI to compute the system loop gain and overall performance.

The tool does not require any specific order to be followed when defining the system blocks, but the following order is recommended as it will facilitate the compensator design:

  1. Define the System or Plant information
  2. Define the Feedback
  3. Design and optimize the Compensator

See "Related Application Notes" for more information on how to extract the describing transfer functions from the specific hardware topologies.
