Temporal Continuity Expression for Network Topology of Space Information Systems

Electronics, Journal Year: 2024, Volume and Issue: 13(14), P. 2824 - 2824

Published: July 18, 2024

The main functions of the space information system, such as providing backbone transmission, broadband access, and global connectivity, are realized based on network topology. Thus, it is necessary to recognize temporal dynamics A continuity expression method proposed describe topological dynamic characteristics in systems. Based orbit dynamics, a time-dependent adjacency matrix system can be established by introducing geometric linkable factor, link distance intensity relative angular velocity factor node. describes from two layers: one physical layer using function, which represents feasibility inter-satellite construction cycle; other transport layer, described piecewise continuous function that varies with time, characterizes quality during connection period between satellites. results show compared existing topology description methods, more accurately, distinguish at any conducive understanding application system.

Constant Force Control and Trajectory Planning of Multi-Axis Polishing Machine Using Active Disturbance Rejection Control and B-Spline Curve Algorithm

IEEE Access, Journal Year: 2024, Volume and Issue: 12, P. 99851 - 99871

Published: Jan. 1, 2024

The traditional force control strategy is on the basis of impedance control, which adjusts position by adjusting mechanical between end effector and environment to achieve constant control. In this paper, a new based B-spline curve active disturbance rejection (ADRC) introduced, realized verified in polishing machine system for curved surfaces. First, modeled as object. Then, used plan trajectory path, ADRC algorithm calculated each interpolation period realize advantage work use generate only needs few points motion auto-disturbance differential tracker estimation real-time force. A simulation using MATLAB software experiment are performed test effectiveness proposed strategy. experimental results show that has better performance compared controller terms consistency, accuracy, surface quality. analysis shows force-tracking exhibits performance, with errors at 0.634mm, overshoot 4.16%, 98.40% reduction roughness. Conversely, PID 96.25% roughness reduction, yields 2.91mm 13% overshoot, proving less precise high-precision tasks.

Sofware-Defined Radio Testbed for I/Q Imbalanced Single-Carrier Communication Systems

Electronics, Journal Year: 2024, Volume and Issue: 13(15), P. 3002 - 3002

Published: July 30, 2024

An end-to-end testbed for In-phase and Quadrature (I/Q) Imbalance (IQI) communication systems based on Software-Defined Radio (SDR) is presented. The scenario under consideration a Single-Input–Single-Output (SISO) single-carrier where the transmitter heavily affected by IQI, whose effects are mitigated through digital signal processing at receiver. presented highly configurable, enabling testing of different IQI parameters. Crucial insights into practical implementation mitigation techniques, specifically use asymmetric signaling receiver, provided. Initially, detailed description mathematical framework given. This serves as foundation subsequent discussion system implementation, effectively bridging gap between research its application in architectures. Over-The-Air (OTA) Symbol Error Rate (SER) measurements constellations validate receiver design implementation. source code publicly available.
