Anticipatory RL improves trajectory tracking, but sim-to-real gap persists

Researchers have developed a new approach called Anticipatory Reinforcement Learning (ARL) to improve trajectory tracking in industrial control systems. This method augments the state space with future reference horizons, aiming to reduce lag and overshoot common in purely reactive DRL systems. While simulations showed a significant 9-fold reduction in error, transferring the model to physical hardware revealed a sim-to-real gap. Interestingly, a simpler ARL configuration with a single look-ahead horizon achieved comparable real-world performance to more complex models, suggesting that highly granular predictive data is not always necessary for effective physical transfer.
