基于PLC的电液伺服系统控制器硬件设计

摘要

目前，PLC在电液伺服控制系统中的应用越来越普遍。本文以S7-300为核心，介绍了根据系统的控制要求，计算和选择PLC的CPU、输入、输出及电源等模块的方法。最终得到了一套符合控制要求的硬件系统。%At present, PLC is used more and more generally in Electro-hydraulic Servo System. As the core of S7-300 in this article, introduced select and calculate methods of CPU module, input module, output module, power module and so on. Finally, select a suit of hard-system, which fit standard of control.
