Communication Link Configuration for Cooperative Control Under Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooperative control algorithms in communication systems face challenges due to data packet losses in wireless communication links, which degrade control performance and require high convergence speeds to react to perturbations, often leading to over-dimensioned systems and coexistence issues, especially in scenarios like vehicle platoons.
Innovation Solution
A method for configuring communication links between communicating nodes arranged in a fixed regular formation, optimizing communication parameters to balance control performance and interference, by selecting candidate neighbor node communication patterns and parameter values that satisfy predetermined criteria for convergence speed and interference levels, thereby reducing interference while ensuring control requirements are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication parameters are optimized to maximize communication performance and reduce packet losses, then control performance is improved, but system complexity and interference increase
Solution Approach 1:
The patent segments the system into independent communicating nodes with standardized communication interfaces. Each node independently configures its communication parameters based on local measurements, avoiding centralized complex optimization. The formation is divided into discrete neighbor relationships that can be individually managed.
Solution Approach 2:
Each communicating node autonomously measures communication performance metrics (packet loss rate, convergence speed) and self-configures its own communication parameters without requiring complex centralized control. The system serves itself through distributed autonomous decision-making at each node.
2Speed
If communication parameters are optimized to ensure fast convergence speed, then control performance is improved, but interference levels increase
Solution Approach 1:
The communication parameters are made dynamic rather than fixed. Nodes continuously measure convergence speed and packet loss rates, then adaptively adjust communication parameters in real-time. This dynamic adaptation allows the system to achieve fast convergence when needed while reducing interference during stable operation.
Solution Approach 2:
The patent changes communication parameters (transmission power, data rate, timing) based on measured performance metrics. When convergence speed is insufficient, parameters are adjusted to accelerate convergence; when performance is adequate, parameters are relaxed to reduce interference and energy consumption.
3Reliability
If communication links are configured to handle packet losses, then reliability is improved, but system complexity increases
Solution Approach 1:
Each node continuously monitors communication reliability metrics such as packet loss rate and uses this feedback to adjust communication parameters. The feedback loop enables the system to maintain robustness against packet losses through simple reactive adjustments rather than complex proactive configurations.
