Abstract

A fast estimator is proposed and applied to the problem of range identification in the presence of unknown motion parameters. Assuming a rigid-body motion with unknown constant rotational parameters but known translational parameters, estimation of the unknown parameters is achieved by a fast estimator, followed by recursive least square extraction. The results are also extended to the case of an affine motion. Simulations demonstrate the superior performance of fast estimation in comparison to an identifier-based observer.
