模糊控制热真空环境模拟设备设计与实现

Design and realization on the simulation equipments of hot vacuum environment based on fuzzy control

设计了一个基于PLC的数据采集系统,用来对真空仓系统中指定各个点的温度实现采集;通过RS232串行通讯方式将数据传给工控机;温度采用模糊控制方法。以MCGS为仿真平台,对真空仓温度控制系统进行了仿真。结果表明,模糊控制器的鲁棒性强,响应速度快,可以达到预期的效果,能够满足太空设备地面试验要求。

A data collection in vacuum room system system based on PLC is designed to collect the temperature of each appointed point RS232 serial communication is used to transmit the data to the industrial computer. The fuzzy control is used to control temperature. Take MCGS as emulate flat, the vacuum room temperature control system is emulated. The result shows that the fuzzy controller has strong robustness and quick response, can satisfied the request of the ground test of aerospace equipments.
