摘　　要：针对机械吊臂的自动化连续控制需求,提出了基于PLC的自动控制技术,介绍了机械吊臂驱动控制组成结构和各模块的主要功能。系统通过PLC对变频器的控制,实现了对交流异步电机的连续变频、变压调节,从而实现对机械吊臂的高精度灵活控制。在PLC控制模块中,重点分析了基于模糊控制策略的非线性控制方法和PLC和主控模块的通信方案,解决了PLC控制过程中两个关键问题。In view of the mechanical handling arm automated stepless control demand,proposed automatic control technology based on the PLC,introduced the mechanical handling arm composition structure and the various modules major function in details.The system control the frequency changer through PLC,has realized the exchanged asynchronous machine continual frequency and voltage conversion,then realized the mechanical handling arm high accuracy controls nimbly.In the PLC control module,the selective analysis misalignment control method based on the fuzzy control strategy and PLC and the master control module correspondence plan,has solved in the PLC controlled process two key problems.
