摘要：

We provide new designs for multivariable extremum seeking for static maps with arbitrarily long time delays. We allow different delays in each input channel and output delays, and gradient- and Newton-based frameworks. Our sequential predictor based approach provides an alternative to earlier prediction methods, and leads to extremum seeking designs where a dynamical extension eliminates the need for distributed terms. Our source seeking example illustrates the good performance of our methods. (C) 2020 Elsevier Ltd. All rights reserved.
