To enhance the reliability of digital automation systems in Industry 4.0 era, this paper investigates a robust fault-tolerant control scheme discrete-time domain subject to periodic disturbances, consisting fault estimator, dynamic disturbance compensation loop, and controller. The estimator simultaneously estimates both system states actuator/sensor faults. existence stability conditions proposed are given, design method is make state disturbances. further reduce estimation errors caused by...
Abstract Precise timing plays a key role in the time‐sensitive industrial Internet of Things (IIoT). However, precise time synchronization requires more frequent packet exchange, which consumes communication bandwidth and energy. This is particular challenge battery‐powered wireless nodes, low costs have become an important factor clock synchronization. To address achieving cost distributed sensor networks, this paper proposes improved event‐triggered control scheme with novel asynchronous...
Summary This article proposes a generalized PI observer with approximate disturbance decoupling (ADD‐GPIO) for detecting incipient actuator faults of system subject to periodic input disturbances. Robustness disturbances and sensitivity is achieved through dynamic configuration the transmission zeros pole‐optimization respectively. By incorporating ‐gap metric index, novel interpretable fault optimization objective function proposed. It first time in detection design that difference between...
Time synchronization is of significance in the Industrial Internet Things (IIoT). For impact energy-constrained batteries for power IIoT, a novel low-overhead time algorithm via one-way single packet exchange, i.e., improved packet-coupled oscillators (I-PkCOs), proposed this paper, which mainly consists time-information exchange protocol according to time-division multiple access scheme and an adaptive proportional-integral feedback clock adjustment algorithm. adjustment, controller used...
To improve the clock synchronization accuracy of wireless networks subject to period disturbance caused by transceiver, this paper develops a perturbation compensation loop with capability compensating periodic perturbations. The stability closed-loop system is analyzed. Improved Particle Swarm Optimization (IPSO) algorithm proposed optimize parameters system. scheme based on General Proportional Integral Observer (GPIO). Compared traditional protocol without GPIO compensator numerical...
With the development of smart cities and wireless communication technology, demand for sensor devices is increasing, low power consumption as an important indicator, there are more scholars conducting related research, event-triggered control has advantages than time-triggered when handling energy resource constraints. In this paper, distributed networks (WSNs) systems with external disturbances, we propose observer-based event triggered discrete-time strategy. By designing observer to...
Aiming at robust fault detection problems subject to external disturbance with a specific spectrum, this paper proposes new filter by combing the dynamic observer and complex coefficient gain. In order improve performance of minor an early stage, focus proposed design is reduce adverse impacts caused spectrum. This achieved through two-stage procedure. First, additional zeros introduced observer's integration actions are allocated near frequency, gain transfer function matrix relating from...
