Compressor System Modeling for Precise Control and Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compressor systems lack a generalized structure for analysis and control, leading to limited evaluation and control capabilities due to the absence of specific knowledge about the system's structure and causal relationships between components.
Innovation Solution
A method that uses derived models based on initial models of the compressor system, accounting for causal relationships and dynamic processes, to enhance control, monitoring, diagnostic, and evaluation routines, allowing for precise control and monitoring tailored to specific compressor systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a standard control and analysis method is used with parameterization, then the method is easy to implement and adaptable to different sites, but it cannot precisely account for the specific circumstances and structural interrelationships of each compressor system
Solution Approach 1:
The patent segments the compressor system into individual component models (compressors, dryers, filters, tanks, consumers) that can be independently defined and then combined. This allows the system to capture specific structural interrelationships while maintaining modularity. The segmentation enables precise modeling of causal relationships between components without requiring a completely custom approach for each system.
Solution Approach 2:
The patent implements dynamic modeling capabilities that allow the system to adapt to changing operating conditions and system configurations. The models can dynamically simulate different scenarios, configurations, and operational states, enabling precise analysis of specific system circumstances while using a standardized framework that can be applied across different compressor systems.
2Productivity
If a mathematical model of the compressor system is used for control, then the control can be optimized, but the model may not capture the specific structural relationships and causal interactions between individual components
Solution Approach 1:
The patent breaks down the overall system model into segmented component models that explicitly represent individual compressors, peripheral devices, and their interconnections. This segmentation preserves structural information about system architecture while enabling optimized control through the integrated behavior of the component models.
Solution Approach 2:
The patent uses an information model as an intermediary layer between the physical system and the control algorithms. This information model captures structural relationships and causal interactions, serving as a mediator that translates physical system characteristics into control-relevant data without losing structural information.
3Adaptability or versatility
If individual analysis of each compressor system is performed without a general structure, then specific system characteristics can be captured, but the analysis and evaluation capabilities are limited
Solution Approach 1:
The patent creates a universal modeling framework that can be applied to any compressor system regardless of its specific configuration. The standardized component models and their interconnection rules provide multi-functionality, enabling the same framework to analyze diverse systems while capturing their specific characteristics through parameterization and configuration.
Solution Approach 2:
By segmenting the system into standardized components, the patent enables individual analysis of each element while maintaining the ability to evaluate the overall system. The segmented approach allows comprehensive analysis capabilities to be applied systematically across different system configurations.

AI summary
The method involves arranging compressors (11, 12, 13) and peripheral devices e.g. filters (14-16), valves (17, 18) and driers (19, 20), in a predetermined configuration. Derived models are created on the basis of initial models of a compressor system, where the initial modules comprise specification of the compressors and the peripheral devices and the derived models include operative interrelationships among the compressors and peripheral devices. The derived models are formed as basis for subsequent control, monitoring, diagnosis or evaluation routines. Independent claims are also included for the following: (1) a compressor system (2) a controlling and/or monitoring unit.
