 In modern process industries, the dynamic characteristics and complexity of processes are continuously increasing, posing challenges to model-based optimization control methods. In addressing the pressing issues within the field of process control, the applicant has developed a framework for reinforcement learning control that integrates both knowledge and data, leveraging the principles of dynamic programming theory.

1. A high-performance framework of inverse reinforcement learning with reward and policy optimization is proposed, addressing the challenging problem of reward design in reinforcement learning to provide theoretical and methodological support for engineering applications of reinforcement learning.

2. A complex process system graph deep reinforcement learning application framework is constructed based on a graph representation model of complex process systems and graph deep learning, achieving automated industrial knowledge extraction and reconstruction in the domain of complex process systems through collaborative driving of both prior knowledge and data.

3. A multi-objective decision & optimization method of deep reinforcement learning is proposed under safety constraint conditions, providing a novel solution for the intelligent management of complex process systems, with a focus on green, low-carbon, energy-efficient, and productivity-enhancing objectives.
