A Model Predictive Approach to Wireless Networked Control

چکیده
In Wireless Networked Control Systems (WNCS), time-varying and unknown delays can significantly degrade the closed-loop performance and even lead to instability. This paper proposes using Dynamic Matrix Control for WNCS, where, a set of predicted control signals corresponding to possible delays are sent to the plant. Here the most appropriate control signal is selected based on the round-trip delay as a QoS measure of the wireless channel condition. Results from Monte Carlo simulations on a cart-mounted inverted pendulum confirm the efficacy of the method. The random delay introduced by WNCS are modelled by an Inverse Gaussian distribution derived from experiments on an IEEE 802.11b network.

Modelling and Compensation of uncertain time-delays in networked control systems with plant uncertainty using an Improved RMPC Method
Control systems with digital communication between sensors, controllers and actuators are called as Networked Control Systems (NCSs). In general, NCSs encounter with some problems such as packet dropouts and network induced delays. When plant uncertainty is added to the aforementioned problems, the design of the robust controller that is able to guarantee the stability, becomes more complex. In...

In this paper, a synthesis method based on robust model predictive control is developed for compensation of uncertain time-delays in networked control systems with bounded disturbance. The proposed method uses linear matrix inequalities and uncertainty polytope to model uncertain time-delays and system disturbances. The continuous system with time-delay is discretized using uncertainty po...

The Networked Control System in modern control widely uses to decrease the implementation cost and increasing the performance. NCS in addition to its advantages is inevitable. Nevertheless they suffer of some limitations and deficiencies. Packet loss is one of the main limitations which affect the control system in different conditions and finally may lead to system instability. For this reason...
متن کاملMarkovian Delay Prediction-Based Control of Networked Systems
A new Markov-based method for real time prediction of network transmission time delays is introduced. The method considers a Multi-Layer Perceptron (MLP) neural model for the transmission network, where the number of neurons in the input layer is minimized so that the required calculations are reduced and the method can be implemented in the real-time. For this purpose, the Markov process order...
