Hybrid Bandwidth Scheduling for CAN-based Networked Control Systems
نویسنده
چکیده
A hybrid bandwidth scheduling scheme is proposed to improve the quality of service and the bandwidth utilization for the CAN-based networked control systems. It combines rate monotonic and improved round-robin scheme for both the realtime and non-real-time data. Moreover, considering the constraints of control performance and network schedulability, a heuristic branch and bound & genetic algorithm (GA) algorithm is presented for the control data to minimize their bandwidth occupancy and the jitter caused by improper scheduling. The residual bandwidth is allocated to non-real-time data by the proposed scale round-robin scheme such that their network loads are

A co-design for CAN-based networked control systems
The goal of this paper is to consider a co-design approach between the controller of a process control application and the frame scheduling for CAN-Based Networked Control Systems in order to simultaneously improve the Quality of Control (QoC) of the process control and the Quality of Service (QoS) of the CAN-based network. First, we present a way to calculate the closed-loop communication time...

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...
متن کاملTime Delay and Data Dropout Compensation in Networked Control Systems Using Extended Kalman Filter
In networked control systems, time delay and data dropout can degrade the performance of the control system and even destabilize the system. In the present paper, the Extended Kalman filter is employed to compensate the effects of time delay and data dropout in feedforward and feedback paths of networked control systems. In the proposed method, the extended Kalman filter is used as an observer ...
متن کاملModelling 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...
