In this paper, the authors research on the scheduling and control co-design of networked control systems (NCSs) to enhance the performance of control systems. Optimization of sampling period is the basic way in co-design of scheduling and control. During the study, the sampling periods of networked control systems with multiple control loops have been scheduled by rate monotonic (RM) algorithm to...
The great advances in microelectronics and MEMS (micro-electro-mechanical system) make it possible to design real-time control loops over wireless networks. Real time character is the common request of control systems, multitask is the mainstream of the distributed control system nowadays. Aiming at selecting communication protocol in the wireless networks, the TrueTime toolbox is applied to establishing...
This paper presents a two-point estimate (TPE) based method for probabilistic analysis of small signal stability of a microgrid (MG) considering uncertainties. The uncertainties may arise from different sources as load demand or generation unit outages. This method combines the TPE method and probabilistic small signal stability analysis. Stability indices and the judgment of unstable types for microgrid's...
In some networked control systems (NCSs), the core computer roles the whole system, processes and schedules all the data transferred from the network nodes. Control networks construct the infrastructures of the NCSs. And, the working efficiency of the network communication is the key element of the entire system. The paper presents a novel media access control (MAC) approach with variable priority...
