摘要

Grab is a common tool in the transportation industry.Traditional grabs have shortcomings such as low automation,limited mining precision,and low operational efficiency.The improvement of automation and intelligence level is an urgent demand in the current market.Grab control system usually adopts AC asynchronous motor as the execution component.Due to its nonlinearity and strong coupling,the existing single closed-loop control method is difficult to achieve the dynamic requirement of position tracking.In order to further improve the accuracy and robustness of the grab position control,a new intelligent control method is proposed.This method adds a position closed loop to the existing AC speed control system to form a triple control system including current,speed and position loop,which could realize real-time adjustment of the position loop parameters through fuzzy PID control.The simulation results show that the above control method has better response characteristics and anti-interference ability,and has better practicability for improving the excavation quality of the grab.
