To realize the automation of the shearer,one of the most important problems is the automatic height adjustment of the shearer cutting-drum,namely,the accurate tracking of the running trajectory for the shearer *** to the repeatability of the cutting process and the characteristics of cutting system,the adaptive iterative learning control is adopted in the memory cutting to accomplish the *** simplified dynamic mode of shearer cutting system is established,and the kinetic equation is got by the Lagrange method in this *** adaptive iterative learning control law is selected,according to the control *** adaptive iterative learning controller is designed,and the algorithm is *** conclusion that the target trajectory can be tracked accurately using the adaptive iterative learning algorithm is got by simulations.
