在多時延影響下，網絡控制系統的控制效果將有所下降，甚至可能不穩定。針對這種情況，文章對系統輸出誤差變化與多個時延之間的關系進行了“量化”描述，并建立了兩者之間的函數關系式Φ，通過Φ反映了多時延對系統性能的影響。文章最后通過實例仿真驗證了該函數關系式的有效性。

Real-Time Errors Analysis of Multiple Time-delays Networked Control System
LI Hua，Zhang Rong-biao，Zhang Yun-feng (Inst.of Electric and Information Engineering ,Jiangsu Univ.,Zhenjiang 212013,China) Abstract: Under multiple time-delays, the control effect will be affected, the? systemperformance will degenerate and even the system will be out of control. Aiming at this, the paper described the relation between the system output errors variety and multiple transmit delays by founding the function Φ. The usefulness of the Φ is validated at last.
Keywords: multiple transmit delays；real-time errors；networked control system
