In order to approximate the behavior of hysteresis nonlinearity which often severely limits the performance of system and improve the prediction accuracy of classical Preisach model (CPM), a least squares support vector machine (LS-SVM) based model is presented in this paper. According to the geometric characteristics of multi-loop hysteresis, the input(More)
Shearer height adjusting is a key technology for coalmine unmanned working face. On the basis of establishing Shearer working face mathematical models, this paper determined related parameters influencing the Shearer height adjusting, then analyzed traditional Shearer memory cutting strategy and pointed out its shortcomings. Aiming at changing technical(More)
