Walking synchronization control of mining straddle bolting rig

In this paper, with a type of mine straddle bolting rig as the research object, the mechanical model and the traveling hydraulic circuit model of the crawler traveling device are established. Due to the inadequacy of the load-sensitive system in controlling the synchronization of the bolting rig, the dual-motor synchronization control technique combined with fuzzy PID was introduced through co-simulation. It was discovered that the application of cross-coupled fuzzy PID for load-sensitive synchronization control significantly reduces speed fluctuations and walking deviations during the operation of the straddle bolting rig.
