Automatic control method of cutting speed regulation of longitudinal roadheader considering temperature load of cutting part

With the continuous development of the energy industry, the longitudinal roadheader has become one of the important equipment. However, the traditional automatic control method of cutting speed regulation of longitudinal roadheader is unstable because of its poor calculation ability of temperature load of cutting part. Therefore, the cutting speed control method of longitudinal roadheader considering the temperature load of cutting part was designed to optimize this kind of problem. The mathematical model of cutting head of longitudinal roadheader was constructed from two aspects, including vertical movement and horizontal movement. The thermal conductivity formula was used to calculate the temperature load of the cutting part. The PID controller was selected as the basis of automatic control, and the above design part was combined to realize the automatic control of cutting speed regulation of roadheader. At this point, the design of the cutting speed regulation automatic control method of the longitudinal roadheader considering the temperature load of the cutting part was completed. By comparing with the other two methods, the control cycle of this design method was the most stable. Therefore, considering the temperature load of the cutting part, the cutting speed regulating automatic control method of the longitudinal roadheader has high control ability.
