A new method of fault diagnosis based on network-induced delay is presented in this paper to solve the problem of optimal control in networked control systems. The probability distribution of the network-induced delay is discussed. A stochastic optimal controller is designed, which is shown to render corresponding networked control systems mean square exponentially stable.
This paper focuses on fault detection of networked control systems with both time-varying delay and packet dropout. Different from some existing results, in this paper, network-induced delay is not limited to be an integer multiple of the sampling period, and packet dropout is present in both sensor-to-controller link and controller-to-actuator link. The method in this paper can be regarded as an...
Fault detection of networked control systems (NCS) is a new research region. The key point of the issue is how to deal with the network-induced delay. In this paper, influence of the delay is regarded as multiplicative faults and a new fault detection approach robust to the delay is proposed. Simulation results show that it can operate well even in conditions that delay is longer than the sampling...
