Restricted Structure Linear Quadratic Gaussian Benchmarking

Using the Restricted Structure Linear Quadratic Gaussian (RS-LQG) method, the order of the controller can be pre-specified and made available within the benchmark calculation. RS-LQG requires the plant model to be known.

When to Use RS-LQG
  • When cost functions involve a sum of squared energy and performance terms.
  • When the controllers to be benchmarked are of a restricted structure.
  • When plant models are known or can be obtained.
When Not to Use RS-LQ
  • When simplicity of the benchmarking method is paramount.
  • When engineers do not wish to spend time selecting the performance they are looking for.
