【摘要】：擁塞控制是使網(wǎng)絡(luò)正常高效運行的關(guān)鍵技術(shù)之一。由于實際網(wǎng)絡(luò)中的一些系統(tǒng)狀態(tài)無法直接獲取,因此現(xiàn)有的網(wǎng)絡(luò)擁塞控制方法常采用狀態(tài)觀測器來獲取系統(tǒng)狀態(tài),從而實現(xiàn)狀態(tài)反饋控制。但當(dāng)系統(tǒng)存在不確定性和非線性干擾時,傳統(tǒng)的線性觀測器不能滿足要求。為此在系統(tǒng)中引入滑模觀測器,對系統(tǒng)不確定性和非線性干擾均具有很好的魯棒性。并提出基于滑模觀測器的狀態(tài)反饋網(wǎng)絡(luò)擁塞控制方法,進行計算機仿真研究。仿真結(jié)果表明,所提出的基于滑模觀測器的網(wǎng)絡(luò)擁塞控制方法具有很好的控制性能。
[Abstract]:Congestion control is one of the key technologies to make the network run normally and efficiently. Because some system states can not be obtained directly in the actual network, the existing network congestion control methods often use the state observer to obtain the system state, thus realize the state feedback control. But when there is uncertainty and nonlinear disturbance, the traditional linear observer can not meet the requirements. Therefore, the sliding mode observer is introduced into the system, which is robust to the uncertainty and nonlinear disturbance of the system. A state feedback congestion control method based on sliding mode observer is proposed and studied by computer simulation. Simulation results show that the proposed network congestion control method based on sliding mode observer has good control performance.
