The use of a communication network in a control loop has gained increasing attention in recent years, because it can offer many advantages. One of major challenges in this so-called networked control systems (NCS) is the network-induced delay effect in the control loop. In this paper, a networked control strategy based on generalized predictive control (GPC) is presented, which can compensate for...
The different effects of the sensor-to-controller and the controller-to-actuator delays in networked control systems, are investigated within the packet-based control framework. The study starts with identifying the specific control strategies that make those two delays different for the system. The problem is then carefully formulated and theoretical analysis is conducted, revealing that under certain...
This paper discusses design of Networked Control Systems (NCS). NCS are distributed control systems whose sensors, actuators and controllers are interconnected by shared industrial network. The major NCS problem is network-induced delays. These delays caused by the sharing of communication medium can be constant, bounded, or even random and can degrade system's performance. The main goal of the paper...
In a networked control system (NCS), the plant and the controller are spatially separated and the control loop is closed through a communication network. Communication time delay in an NCS degrades the performance and may lead to instability. In this paper, the scattering transformation is applied to NCS, for the first time, in order to guarantee stability in the presence of unknown constant time...
