A Model for Reconfiguration of Multi-Modal Real-Time Systems under Energy Constraints

Performance and energy aware robust specification of control execution patterns under dropped samples

“…On the other hand, in power‐limited embedded control systems, power efficiency is one of the important concerns since the ECU, sensors, and actuators can be battery powered having individual/shared power supplies. A significant amount of research works has been carried out in this direction focusing on energy aware design of the system [18, 27–30]. An energy‐aware scheduling for weakly hard real‐time constrained [31] tasks running on the multiprocessor platform is reported in [29].…”

“…Similarly, in [27], the authors develop a framework that maximises the system's quality of service while guaranteeing schedulability and energy constraints but in a multi‐mode fashion. Both these works [27, 28] assume that the tasks may have different modes of operation having a specific quality of service in each of these modes. Though all these aforementioned works consider the scheduling and energy issues together, they do not consider the non‐ideal effect of the underlying computing platform as well as the stability and control performance related issues as we take care of in this work.…”

“…Similarly, in [18], a two‐step energy management technique is proposed to maximise the quality of service (in the form of weakly‐hard constraint) of the real‐time tasks guaranteeing best energy utilisation under a given energy budget. The work presented in [28] provides a framework that maximises the quality of service of the given real‐time system such that the system meets schedulability and energy requirements. Similarly, in [27], the authors develop a framework that maximises the system's quality of service while guaranteeing schedulability and energy constraints but in a multi‐mode fashion.…”
