Abstract

We provide a method for gradient-based multivariable extremum seeking that allows different delays in each input channel. We allow output delays, and for the delays to be arbitrarily long. We use averaging and a perturbation based estimate, but our sequential predictor based approach provides a useful alternative to the distributed terms that were used in earlier delay compensation approaches to extremum seeking. We illustrate our approach in a source seeking example.
