针对具有线性时不变被控对象的网络控制系统,讨论了在控制器为时钟驱动和事件驱动两种情况下的连续最优性能指标到等价离散最优性能指标的转换,结果也表明,当网络诱导时延小于一个采样周期时在控制器的两种驱动方式下,网络控制系统具有相同的等价离散性能指标。其中被控对象和系统输出中皆含有连续的白噪声。
Aiming at the networked control system with invariant object under linearity, the paper discusses the conversion of continuous optimal performance index to equivalent discrete optimal performance index under the condition that controller is clock driven and event driven. The results also show that, When the network induced delay is less than one sampling period, the network control system has the same equivalent discrete performance index under the two driving modes of the controller. The controlled object and the system output all contain continuous white noise.
