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...
A kind of MIMO networked control systems, in which the sensors and controller are interconnected by network and the state of control object is feedback to the controller and each loop is controlled at different sampling period, is studied in this paper. Supposed that the maximum network-induced delay is smaller than one sample period, its model is established. Based on estimation theorem of feature...
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...
Aimed at a kind of multi-input & multi-output networked control systems with the sensors and controller interconnected by network and the output variable are controlled at different sampling period, its structure and model and stability are studied in this paper. Supposed that the maximum network-induced delay time is smaller than one sample period, the model of the networked Control system is...
This paper proposes an optimal control solution for the L2-gain disturbance rejection problem for networked control systems. The problem, usually referred as mixed H2/H∞, aims at designing a linear stabilizing controller minimizing a given cost function subject to a L2-gain disturbance rejection constraint. The problem is formulated assuming network induced time-varying delays and/or packet losses...
This paper considers a design problem of controllers for our developed networked control system based on state predictive control. Our developed system consists of a wireless vehicle, a router in a computer network and a computer as the controller. Because the router has an AQM mechanism to keep the queue size constant, our networked control system can be described as linear systems with an input...
