A kind of MIMO networked control system, in which each state signal of object controlled is obtained by an independent sensor and then sent to a single controller through a network, and also each output signal of the controller is sent to an independent actuator through the network, is studied in this paper. The figure of its structure is given, and its mathematic model is set up. Based on the Lyapunov...
It is well known that control of PDEs with input delay is just opening up for research. This paper presents boundary control design and stabilization for a reaction-diffusion PDE with diffusion coefficients depending on space variable and input time delay. The control design involves an interesting structure of two interconnected PDEs to transfer the input time delay into a space extension. And the...
This paper addresses a practical networked based control application. A Profibus DP is considered in order to coordinate a triangular maglev platform. The control of this magnetic levitation process is a complicated system from an control engineering point of view due to its unstable, non-minimum phase and non-linear nature; the difficulty is growing up because the bandwidth limitation and some other...
The message dropout will degrade the control performance in the Internet-based telecontrol system. The switched controller is proposed to compensate the network delay and message dropout. It changes among the different structures by inspecting the sampling cases in the forward and feedback paths. The theory analysis shows that the stability and steady-state error will be maintained, but the transient...
