In this paper, adaptive state feedback stabilizing controllers for networked adaptive control systems with actuator failures are developed. The problems of networked control systems such as; transmission delays and data-packets dropout induced by the insertion of data networks in the feedback adaptive control loops are also considered. Sufficient conditions for Lyapunov stability are derived in the...
Wired and wireless network delays highly degrade the control performance of hybrid networked control systems(HNCS). In order to effectively restrain impact of network delay for the HNCS, a novel approach is proposed that new Smith predictor combined with fuzzy radial basis function neural network (FRBFNN), and comes true delay compensations. Because new Smith predictor does not include network delay...
In this paper, the packet-based control approach to networked control systems is extended to the continuous time case, with the use of a discretization technique for the continuous network-induced delay. The derived approach can effectively deal with network-induced delay, data packet dropout and data packet disorder simultaneously, and also leads to a novel model for networked control systems. This...
Fault detection problem for a type of SISO networked control systems is studied. We can avoid considering the delay of forward loop by located the smart nodes. The networked induced delay can be obtained by time-stamp, and coupled with identification technology, a self-adaptive predicted technology is used to compensate the delay of feedback loop. A fault detection algorithm for a type of fault is...
The variable time delay and the packet loss degrade the performance of Internet based teleoperation system seriously, even make the system unstable. To overcome the trouble, an idea that using CARIMA model of the linearized slave robot to design a controller based on the Generalized Predictive Control (GPC) method is proposed in this paper. We place the GPC controller at the remote site. First of...
Remote control and monitoring are very necessary in decentralized manufacturing environments. This is evidenced by todaypsilas distributed shop floors where agility and responsiveness are required to maintain high productivity and flexibility. However, there exists a lack of an effective system architecture that integrates remote condition monitoring and control of automated equipment; that give much...
