摘要
通过分析分布式系统中由于网络数据传输的时滞现象而带来的前向通道和反馈时滞环节对系统控制性能的影响 ,设计了基于Smith预估原理的预估控制器。通过简化得到等效的滞后校正环节并进行了修正。根据滞后校正环节的频率特性进一步简化 ,得到工程实用的PI控制器模型。最后对设计的预估控制器进行仿真验证 ,表明所设计的PI控制器具有较好的控制效果和对时滞变化的鲁棒性 。
The transform time-delay of the data in the distributed aircraft onboard electromechanical equipment control and management integrated system would cause the is considered. The smith Compensable controller is designed, Then the equivalent lag controller is derived and it is been modified. The simple PI control ruler is derived based on the lag controller, and is proved to be highly effective and robust by the digital simulation.
