Robust Control of Hard Disk Drive Servo (Part 2)

This is the second video in the series on Robust Control applied to hard disk drive servo. This video is about the theory and concepts involved in Robust Control for MIMO systems to set the stage for the actual robust control design of HDD servo.

This video approaches the following topics:

  1. How to define the gain of a matrix?
  2. Singular values and H-infinity norm
  3. Setting the robust control problem in terms of singular values and norms.
  4. Unstructured uncertainty and robust stability
  5. Structured uncertainty and robust stability
  6. Performance stability
  7. Now it’s just the tools that are available and our judgement as control engineers.
