In this research, a novel error-decomposition scheme is developed to determine efficiently the random errors of reflector surface based on the discrete measurement data. The least squares fitting of semi-closed B-spline surface is employed. Subsequently, a spatial statistical analysis is performed to determine whether the spatial independent distribution of the sampled data points is attained for...
An accurate friction model is necessary for friction compensation in radar servo systems or industrial robots. In order to obtain an accurate friction model, a method of friction modelling is proposed, based on support vector regression machines (SVRM) and real genetic algorithms (RGA). Three optimization problem formulations are proposed to realize the automatic optimal parameter selection of SVMR...
