Parallelization of a controller parameter tuning task using an aerospace system model as an example
|23 Sep 2009||Linda Webb||
Estimating plant model parameters and tuning controllers are challenging tasks. Optimization-based methods help to systematically accelerate the tun¬ing process and let engineers tune multiple parameters at the same time. Further efficiencies can be gained by running the optimization in a parallel setting and distributing the computational load across multiple MATLAB workers—but how do you know when an optimization problem is a good candidate for parallelization?
Using an aerospace system model as an example, this article describes the paral¬lelization of a controller parameter tuning task using Parallel Computing Toolbox and Simulink Design Optimization. Topics covered include setting up an optimiza¬tion problem for parallel computing, the types of models that benefit from parallel optimization, and the typical optimization speed-up that can be achieved.
