基于PLC的风电回转支承实验台控制系统设计

Design of testing table control system used for wind power slewing bearing based on PLC

以风电回转支承实验台为研究对象,简单介绍了实验台结构原理,阐述了其控制系统原理及构成、下位机程序设计、上位机软件及实验流程等,并以自由口通信为例介绍了其在上下位机中的具体实现。同时针对系统存在的非线性问题,通过逆求控制值的方法进行修正,减小比例阀非线性的影响。

Testing table used for wind power slewing bearing is discussed,which is introduced simply first.Then,some contents are expounded,such as principle and structure of control system,program design in lower computer,program design in upper computer and experimental process.The realization of software is given for example by free-port communication.On the other hand,control values are converse solved to reduce the nonlincarity effect of system produced by proportional valve.
