Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems for facilities with multiple equipment types struggle to efficiently manage and optimize operations due to variations in environmental disturbances and operational states, leading to inefficiencies and suboptimal performance.
Innovation Solution
A control apparatus that integrates feedback and AI-based control methods, utilizing a switching mechanism to dynamically switch between feedback control and AI control based on measured differences and environmental conditions, optimizing operation amounts through learning and reinforcement learning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single control method (feedback or feed-forward) is used, then the control system is simple, but it cannot adapt to varying environmental disturbances and operational states
Solution Approach 1:
The control system dynamically switches between feedback control and feed-forward control based on operational conditions. A switching unit selects which control method to use, allowing the system to adapt to varying environmental disturbances and operational states rather than relying on a fixed control approach
Solution Approach 2:
The control apparatus integrates multiple control methods (feedback control and feed-forward control) into a single system. This multi-functional approach allows the system to handle different types of control scenarios and environmental conditions using appropriate control strategies
2Productivity
If learning-based control is always used, then optimal performance is achieved, but the system becomes complex and difficult to implement
Solution Approach 1:
The system dynamically switches between learning-based control and traditional control methods based on operational conditions. The switching unit determines when to use the learned model for optimal performance and when to revert to simpler control approaches, balancing efficiency and complexity
3Adaptability or versatility
If switching between control methods is implemented, then adaptability improves, but control stability may deteriorate due to frequent switching
Solution Approach 1:
The switching logic is designed to prevent frequent or unnecessary switching between control methods. By establishing clear switching criteria and hysteresis mechanisms, the system avoids instability caused by oscillatory switching while maintaining adaptability to genuine changes in operational conditions
