Scheduling Algorithm of Data Sampling Times in the Real-Time Distributed Control Systems
Seung Ho Hong · 제어로봇시스템학회 국내학술대회 논문집 · 1992
The Real-time Distributed Control Systems (RDCS) consist of several distributed control processes which share a network medium to exchange their data. Performance of feedback control loops in the RDCS is subject to the network-induced delays from sensor to controller and from controller to actuator. The network-induced delays are directly dependent upon the data sampling times of the control components which share a network medium. In this study, a scheduling algorithm of determining data sampling times is developed using the window concept, where the sampling data from the control components dynamically share a limited number of windows.
