Understand the interface decision

Filtering, calculation, communication, actuator limits and rotor dynamics can all affect the response seen at the turbine. A controller can sample rapidly while deliberately changing its loading target more slowly. Conversely, a fast command update can still produce an undesirable response if it excites the mechanical system.

Control performance depends on signal meaning, timing and the approved operating limits. Keep normal optimization separate from protective constraints, and identify which function owns each decision. The selected turbine and controller documentation must define the actual settings.

Put these inputs in the review record

Use a project-specific worksheet to capture the following information. For each entry, name the document, revision and person responsible for resolving any uncertainty.

• The signal sampling interval and any filtering or averaging. Identify the exact configuration and the supporting document.
• The MPPT update interval and commanded variable. Keep the design assumptions visible in the project record.
• Actuation limits and the relevant rotor-generator dynamics. Name the responsible reviewer and resolve any missing information.
• A defined input change and the response quantities to be assessed. State how this entry will be verified during acceptance.

Define the acceptance boundary

Compare controllers using a response definition that names the input, measurement boundary and acceptance criterion. Do not use processor speed or sampling rate alone as a claim of better energy capture. The control behavior must suit the selected turbine.

A response plot should show the input signal, target and measured output with a shared time basis. This lets reviewers identify whether delay comes from measurement filtering, command generation or the physical plant.
