Abstract

This paper explores the use of least absolute deviation as an error criterion for certain tracking and jitter control problems. Minimizing an absolute error versus a squared error leads to a nonlinear control problem. We consider a fixed-gain structure that we solve with dynamic programming, as well as an adaptive approach motivated by both recursive least squares and the fixed-gain approach.
