Physics-informed neural networks enhance safety in reinforcement learning

Researchers have developed a novel approach to enhance the safety of deep reinforcement learning (DRL) in industrial cyber-physical systems. Their method integrates a differentiable physics model directly into the proximal policy optimization (PPO) actor loss function. This allows the policy to be penalized for anticipated safety violations during training, independent of the primary task reward. Tested on a simulated 1-degree-of-freedom helicopter, this physics-informed regularization significantly reduced constraint violations while preserving reliable performance. AI
