Distributed Control Coordination for Multi-Target Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In NFV environments, distributed integrated control lacks a specific control algorithm, leading to control interference and reduced precision due to independent operation of control engines, making it difficult to achieve high extensibility and precision in controlling multiple control targets.
Innovation Solution
A control device with a first calculation unit for each control target, a second calculation unit for evaluating control solutions, a solution change unit to adjust these solutions based on evaluations, and a control unit to implement the changed solutions, ensuring modular and precise control across multiple control targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If distributed integrated control is implemented with independent control engines for each control target, then extensibility is improved, but control precision deteriorates due to control interference between engines
Solution Approach 1:
An information sharing engine is introduced as an intermediary between multiple control engines. This mediator collects control solutions from each control engine, shares relevant information among them, and coordinates their operations to prevent control interference, thereby maintaining control precision while preserving the extensibility benefits of distributed architecture
Solution Approach 2:
The control system is segmented into independent control engines, each responsible for a specific control target, while introducing a separate information sharing engine. This segmentation allows each control engine to operate independently for extensibility while the information sharing engine coordinates them to prevent interference, resolving the precision problem
2Measurement precision
If centralized integrated control is implemented to achieve simultaneous optimization, then control precision is improved, but device complexity increases and extensibility deteriorates
Solution Approach 1:
The centralized control algorithm is segmented into multiple independent control engines, each handling a specific control target. This reduces the complexity of individual algorithms while maintaining coordinated optimization through the information sharing engine, thereby improving extensibility without sacrificing control precision
3Ease of operation
If control engines operate independently in distributed integrated control, then ease of operation is improved, but control precision deteriorates due to lack of coordination
Solution Approach 1:
The information sharing engine acts as a mediator that enables coordinated operation without compromising the operational independence of individual control engines. Each engine continues to operate autonomously on its control target, but the mediator shares information and coordinates solutions to prevent interference, thereby maintaining both ease of operation and control precision
