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 objects under linear time-varying conditions, the conversion from continuous optimal performance index to equivalent discrete optimal performance index in the case of clock-driven and event-driven controllers is discussed. The results show that when When the network induced delay is less than one sampling period, the network control system has the same equivalent discrete performance under the two driving modes of the controller. The controlled object and the system output all contain continuous white noise.
