- 基于事件触发的博弈算法,让控制器自主优化参数
- 温控实验中超调量下降,调节时间显著缩短
- 适合需要自适应控制的工业自动化场景
本文提出一种新型方法,利用事件驱动的动态博弈论提升工业系统中比例-积分-微分(PID)控制器的自适应能力,使控制器能自主学习、优化并精细调整参数。与传统自学习方法不同,该框架采用事件驱动控制策略和博弈论学习算法,各参与方与PID控制器协作,在设定值变化或扰动时动态调整增益。理论分析表明,在合适的稳定区间内,博弈过程具有收敛性保证。此外,引入自动边界检测机制,帮助参与者快速确定动作空间初始值,大幅减少探索时间。该方法在印刷机温控回路中得到验证,结果表明所提出的智能自调参PID控制器表现优异,尤其在降低超调量和缩短调节时间方面效果显著。
原文摘要 · Abstract (English)
This paper presents a novel method for enhancing the adaptability of Proportional-Integral-Derivative (PID) controllers in industrial systems using event-based dynamic game theory, which enables the PID controllers to self-learn, optimize, and fine-tune themselves. In contrast to conventional self-learning approaches, our proposed framework offers an event-driven control strategy and game-theoretic learning algorithms. The players collaborate with the PID controllers to dynamically adjust their gains in response to set point changes and disturbances. We provide a theoretical analysis showing sound convergence guarantees for the game given suitable stability ranges of the PID controlled loop. We further introduce an automatic boundary detection mechanism, which helps the players to find an optimal initialization of action spaces and significantly reduces the exploration time. The efficacy of this novel methodology is validated through its implementation in the temperature control loop of a printing press machine. Eventually, the outcomes of the proposed intelligent self-tuning PID controllers are highly promising, particularly in terms of reducing overshoot and settling time.
