【摘要】:考慮到具有時(shí)變時(shí)延的實(shí)際NCS的非線性特性以及執(zhí)行器發(fā)生失效故障的隨機(jī)性,研究了離散事件觸發(fā)機(jī)制下NNCS主被動(dòng)混合容錯(cuò)控制.首先通過T-S模糊模型建模,并利用并行分布補(bǔ)償方案以及構(gòu)造Lyaounov-Krasovskii泛函等方法,基于H∞控制思想,設(shè)計(jì)了故障檢測觀測器,以實(shí)現(xiàn)對故障的在線檢測;然后通過離線設(shè)計(jì)的被動(dòng)容錯(cuò)控制器確保在已知故障發(fā)生時(shí)系統(tǒng)保持穩(wěn)定,在未知故障發(fā)生初期,能減緩系統(tǒng)性能下降的速度,并通過重構(gòu)控制器來補(bǔ)償未知故障對系統(tǒng)的影響;最后通過一個(gè)仿真算例驗(yàn)證了離散事件觸發(fā)方式對網(wǎng)絡(luò)資源的節(jié)約性以及所采用方法的有效性.
