ABSTRACT

In WNCSs, the sensor and actuator communicate with the controller through wireless networks. The availability attacks are also known as DoS attacks or jamming attacks, and they are realized by corrupting the communication network. Many control systems relying on real-time information become performance loss or even unstable under DoS attacks [193]. In[177], jamming attack scheduling schemes to optimize the linear quadratic Gaussian control cost function for single and multiple systems have been investigated. In practice, all the control systems operate in the presence of disturbances, which are caused by many factors such as load variation [38], friction [186], and measurement noise [168]. Therefore, considering the influence of disturbances on WNCSs is of great importance [45]. The H∞ minmax control has advantages compared with the traditional observer-based disturbance control method when it is difficult to model the disturbances. Nowadays, the sampling intervals in industrial control systems are becoming smaller and smaller with the rapid development of sensing technology. The delta operator method is recommended as an effective way to solve the sampling issues for WNCSs [162]. In the last few decades, some inspiring control results have been reported for the control problems in the delta domain of NCSs [159].
