A Phase Correction Node Construction for Cyber-Physical Systems Based on All-pass Filters
Abstract
Abstract. The article examines a cyber-physical system using the example of an autonomous mobile platform (AMP), which contains hardware and software components. However, AMPs have limitations regarding power consumption, computational capacity, and real-time operation independently. The uncertainty of the environment necessitates the use of means that correct sensor signals. To correct the phase of AMP sensor signals, all-pass filters are used. The paper discusses the construction of all-pass filters based on low-order LPF and HPF, as well as BPF and BRF. Phase correction improvement is achieved by increasing the order of the transfer function through the sequential connection of such filters. Schemes of correction nodes implementation are presented.
