压缩机排气压力的串级控制

The serial control of the compressors discharge pressure

根据控制对象的实际情况，参照现有的类似控制系统，提出了一种适合于压缩机性能测试系统运行过程的控制方案．根据控制过程中对控制精度的不同要求，分阶段采用不同控制算法，并就本串级控制系统的硬件配置和软件设计提出了具体方案．

According to the practical situation of controlled plant and referring similar control systems nowadays used, a control scheme suitable for the operation of compressors performance test system is presented, where different step wise control algorithms are to be employed according to different controlling accuracy requirements during control process. The hardware configuration and software programming of this serial control system are also presented in the form of concrete scheme.
