چکیده انگلیسی
Two critical issues in networked control systems are coupling of control and communication, and energy economy, especially for battery powered wireless sensor nodes. In this regard, a two-level design procedure for multiple loops with Hâ based self-triggered control applied over the modified IEEE 802.15.4 wireless protocol is presented. Control and communication are decoupled by introducing an upper-bound on the transmission rate, and optimal usage of communication bandwidth and energy is guaranteed by modifying the wireless protocol. The presented priority-based scheduling algorithm can accommodate more systems as compared with the number of available transmission slots, while being efficient in terms of computational load and energy consumption. Simulation results show a significant reduction in energy expenditure in terms of decrease in duty cycle as compared with the periodic implementation.
