Shared Network

Networked Control System is the focus of current research in control field, and the use of a shared network introduces new challenges, therefore, it is significant to research scheduling algorithms for improving the control and schedule performance of NCS. In the paper, according to the challenges existing in scheduling algorithms, a new scheduling algorithm called Switch scheduling is proposed, and the calculation method of switching conditions is also given. In the proposed algorithm, network-induced delay and network utilization are considered to satisfy the different network condition with appropriate scheduling algorithm. The proposed algorithm improves the network utilization and the efficiency of data transmission, and guarantees the system stability. Finally, a simulation example is conducted to validate the feasibility and superiority of the proposed switch scheduling.

Bandwidth Scheduling

The performance of Networked Control System (NCS) is not only determined by controller, but also by network QoS. In this paper, aiming at the bandwidth scheduling problem of multiple closed loop control system, an approximate linear function of continuous system performance with delay and sample period is proposed firstly, and then the optimal scheduling algorithm under both non-preemptive rate monotonic (NPRM) schedulability constraint and NCS stability constraint is proposed which is to optimize the overall performance of NCS. Moreover, an algorithm of sample periods harmonization is presented to improve the bandwidth utilization. A reservation-based schedule of non-period data is also taken into account. Finally, an integrated simulation platform based on Truetime is present, and the experimental results show that the scheme is more effective than the former ones.
