Predictive control

Definition

Predictive control is a method used in various systems, including neuroprosthetics, where future states of the system are estimated based on current data and models to optimize performance. This approach allows for better adjustments in real-time by anticipating user needs and movements, which is crucial for improving user training and learning outcomes in neuroprosthetic systems. By predicting how users will interact with their devices, predictive control enhances the adaptability and responsiveness of these systems.
