Context-Adaptive Learning Control Architectures for Distributed Intelligent Actuation Systems

To an increased extent ubiquitous computing environments rely on the distributed intelligent actuation systems which, that is, autonomously adapt to varying environmental condition, user behavior and operational uncertainties. But, the traditional centralized and rule based control techniques have weaknesses of limited scalability, inadequate adaptability, and excessive overhead of communication, which limits their utility in large-scale intelligent systems. The current paper is a proposal of a context-adaptive learning control framework in distributed intelligent actuation systems thatcould work effectively in ubiquitous and intelligent settings. The offered architecture combines the context sensing (using multiple sources), decentralized control based on reinforcement learning and lightweight cooperative coordination to provide adaptive, resilient, and scalable actuation behavior. In part of the contextual information received by heterogeneous sensors is processed and fused to form dynamic context representations, which are used to continuously revise local control policies at distributed actuators. The decentralized coordination mechanism is used to enable actuators near one another to share functionalized learning data to guarantee world performance goals without necessitating centralized controllers. Experiments are carried out simulated in real conditions of a smart building and an intelligent transportation environment to assess system performance. Findings indicate that the new method has distributed improvement of energy efficiency with up to 30 percent, response time to changing context with up to 40 percent faster response and higher resilience by noisy and incomplete contextual information compared with the real schemes of control based on learning that are static and non-contextual. Those results substantiate the fact that context-adaptive learning control is an excellent contribution to autonomy, scalability and resilience of distributed intelligent actuation systems that may offer a practical base to the next generation of ubiquitous computing applications and intelligent environments.
