✦ Synopsis

A method for the analysis of dynamic maximum-seeking systems is presented, utilizing functional series analysis techniques. It is shown that in order to have the controlled quantity follow the value that results in the maximization of a quadratic performance index, a test signal must be injected into the system. The role of this test signal is to produce a linear term in the Telation between the desired and the actual values of the controlled variable. This is a different interpretation from that common in the field where the test signal is presumably needed to gather "information" about the system. The results we not restricted to linear plants and transducers or to invertible elements.

While the mainstream methods of adaptive control (both linear and nonlinear) deal only with regulation to known set points or reference trajectories, in many applications the set point should be selected to achieve a maximum of an uncertain reference-to-output equilibrium map.

We discuss how the choice of dither (excitation signal) affects the performance of extremum seeking using a benchmark situation: a static scalar map; and a simple scalar extremum seeking scheme. Our comparisons are based on the performance of the system with different dithers in terms of three perfo
