摘　　要：在基于因特网的远程控制系统中 ,由于网络信息传输的时延及其不确定性会降低控制系统的性能 ,甚至使系统无法控制。文中提出一种新的动态补偿器的结构 ,通过实时检测网络时延 ,由补偿器中的变结构调节器对系统的动态特性进行补偿 ,避免了预报精度对补偿的影响 ,改善了采用因特网的远程控制系统的控制性能。In Internet based remote control system, because of the time delay and uncertainty of information transmission on network, the performance of control system becomes inferior, even the control action is failed. A new structure of dynamic compensator is stated in the paper. Through real time detecting of time delay on network, dynamic characteristics of the system is compensated by varying structure regulator in compensator, thus the influence of forecasted accuracy to compensation is avoided and the control performance of Internet based remote control system in enhanced. The next target of study is presented.
