© 2014 IEEE. Extremum seeking control is a well-established technique for dealing with the online optimization of unknown dynamic systems. However, in many applications the convergence rate of traditional extremum seeking approaches is a limiting factor, largely arising from the need for full time scale separation between the elements of the closed loop system. Recent theoretical developments have shown that for plants with a Hammerstein structure, it is possible to exploit different tuning regimes for the algorithms, leading to significantly faster convergence speeds. This approach is extended here to a class of Hammerstein-Wiener plants and demonstrated experimentally in a stationary power..
