Stochastic Source Seeking with Tuning of Forward Velocity

Part of the Communications and Control Engineering book series (CCE)

Abstract

An alternative approach to source seeking for nonholonomic vehicles is presented, employing the tuning of the forward velocity, instead of tuning of the angular velocity. In contrast to the approach employing the tuning of angular velocity, where the vehicle never stops as it heads to the source and then enters a complex attractor in an annulus around the source, in the approach employing the tuning of the forward velocity the trajectories consist of back-and-forth arc-shaped motions that converge on the average to the source. The averaging analysis reflects the fact that tuning of the angular velocity yields a superior transient performance, while tuning of the forward velocity yields a superior asymptotic performance.
