CYBER-PHYSICAL MAGNETIC FIELD SENSORS

摘要

This paper studies integrated solid-state Hall effect sensors with processing microelectronics. Many commercialized triaxial magnetometers have III-V semiconductor sensing elements, application-specific integrated circuits (ASICs) and microcontrollers. Processing algorithms are supported by device- and hardware specific architectures, middleware and software. Integrated Hall effect sensors with InSb sensing elements may ensure sufficient accuracy, measurement range, adequate spatiotemporal resolution, linearity, high bandwidth, and fast response time. Nonlinearities, cross-axis coupling, temperature sensitivity and other performance-degrading phenomena are minimized using ASICs which implement filters, compensators, etc. We examine and solve noise attenuation and error reduction problems by processing the ASICs outputs of integrated Hall effect sensors. Noise and error are minimized by using adaptive filters and information analysis. A dynamic mode estimator supports system reconfiguration. The experimentally substantiated laboratory-proven schemes enhance the existing solutions toward CPS-compliant sensing solutions for complex systems.
