在多時(shí)延影響下，網(wǎng)絡(luò)控制系統(tǒng)的控制效果將有所下降，甚至可能不穩(wěn)定。針對(duì)這種情況，文章對(duì)系統(tǒng)輸出誤差變化與多個(gè)時(shí)延之間的關(guān)系進(jìn)行了“量化”描述，并建立了兩者之間的函數(shù)關(guān)系式Φ，通過Φ反映了多時(shí)延對(duì)系統(tǒng)性能的影響。文章最后通過實(shí)例仿真驗(yàn)證了該函數(shù)關(guān)系式的有效性。
關(guān)鍵詞：多傳輸時(shí)延；實(shí)時(shí)誤差；網(wǎng)絡(luò)控制系統(tǒng)；
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
