1Productivity
If traditional process control systems are used, then the system structure is simple and easy to understand, but the system cannot efficiently monitor and adjust operations in real-time, leading to suboptimal performance
Solution Approach 1:
The patent replaces traditional mechanical control systems with AI-based control circuitry that utilizes machine learning and reinforcement learning algorithms. The AI control circuitry processes sensor data, identifies anomalies, and adjusts controller parameters automatically, substituting manual or rule-based control mechanisms with intelligent systems capable of real-time optimization.
Solution Approach 2:
The AI control system implements self-service by automatically monitoring process parameters, detecting anomalies without human intervention, and adjusting controller settings based on learned patterns. The reinforcement learning component enables the system to self-optimize by continuously learning from operational data and making autonomous decisions to maintain optimal performance.
2Reliability
If traditional controllers are used, then the controller parameters are easy to set, but the system cannot identify anomalies effectively or optimize parameters dynamically
Solution Approach 1:
The patent implements feedback mechanisms where the AI control circuitry continuously monitors process outputs and uses this information to adjust controller parameters. The reinforcement learning component receives feedback about system performance and modifies its policy to improve future decisions, enabling dynamic optimization of controller settings based on actual process behavior.
Solution Approach 2:
The system dynamically changes controller parameters based on learned patterns and real-time conditions. The AI control circuitry adjusts PID parameters and other controller settings automatically, replacing static parameter configurations with adaptive parameter tuning that responds to changing process conditions and identified anomalies.
3Speed
If manual monitoring and adjustment is performed, then the system is easy to implement, but it requires continuous manual intervention and cannot respond quickly to changes
Solution Approach 1:
The patent replaces manual monitoring and adjustment operations with automated AI control circuitry. The system uses machine learning models to process sensor data and reinforcement learning to make control decisions, substituting human operators with intelligent algorithms that respond instantaneously to process changes without fatigue or delay.
Solution Approach 2:
The AI control system operates continuously without interruption, constantly monitoring process parameters and making adjustments as needed. The reinforcement learning agent maintains continuous learning and decision-making, ensuring uninterrupted optimal control performance unlike manual systems that require periodic human intervention.
