Generalised Minimum Variance Benchmarking

The Generalised Minimum Variance (GMV) benchmarking method extends the MV method. A dynamic weighting is applied to both the actuator energy and the loop output. This reduces the control activity.

When to Use GMV
  • When control actuator movements have in practice to be limited.
  • When costs of operation involve a misture of performance and energy requirements.
  • When control power must be limited due to actuator drives or power supplies.
When Not to Use GMV
  • When the actual controller to be benchmarked is of low order or has other structural limitations.
  • When the actual controller to be benchmarked is of low order or has other structural limitations.
