压缩机测试系统工况控制策略的研究

在研究压缩机测试系统试验工况之间的数学关系基础上，针对控制系统的硬件选择。提出了一种以D／P转换为核心，用条件概率为描述语言的概率控制技术。将简单的开关控制转变为全波的调压式控制。在测试系统的工况控制中概率控制技术使控制系统有了较高的动静态性能。

Research of control tactics for operating conditionsin compressor refrigerating capacity test system

In accordance with the dynamic distributive parameter mathematical models,this paper puts forward the probability control technique that regards D/P conversion as the core and describs with condition probability.Probability control technique and other control tactics are used for operating conditions.These control tactics are proposed for improving the control precision and the robustness of the system,and speeding up the response process of the test system.A practical application shows that these control technique have better control effect.
