| Abstract: | A experimental miniature shearer is introduced and the hydraulic system is designed. The mathematical model and MATLAB/Simulink dynamic simulation model for the hydraulic system are established, and some simulation examples are carried out. The simulation results show that the system dynamic performance is affected by the amplifier gain coefficient, load and total compression of hydraulic cylinder. Moreover, the system dynamic performance could be improved by a PID controller. The study results provide a theoretical support for the design and optimization of shearer hydraulic system. |
