In the actual transportation engineering system, due to limited hardware control capabilities, there are certain difficulties in the application of advanced algorithms. Aiming at the difficulty of realizing the control algorithm for the material transport system at the current stage, the parameter self-tuning fuzzy PID control algorithm applied to the mate- rial transport was studied. According to the three-phase asynchronous AC motor＇s rotational speed characteristics and material flow control principle, the material transport system was established. The parameter self-tuning fuzzy PID mathematical model, based on the establishment of the system algorithm model, the introduction of the OPC technology, and gives the MCGS and MATLAB OPC configuration and communication methods, the final combination of the two to achieve the parameter self-tuning in the transport system Fuzzy PID Control Algorithm Application. The results show that the OPC communication technology is convenient to use in the process of system debugging. The control system re- flects the stable communication capability and control performance and finally reaches a given standard. This control scheme achieves good data exchange of the UDDer cnrnmltor
