Résumé : In most existing motion control algorithms, a reference trajectory is tracked, based on a continuous measurement of the system's response. In many industrial applications, however, it is either not possible or too expensive to install sensors which measure the system's output over the complete stroke: instead, the motion can only be detected at certain discrete positions. The control objective in these systems is often not to track a complete trajectory accurately, but rather to achieve a given state at the sensor locations (e.g. to pass by the sensor at a given time, or with a given speed). Model-based control strategies are not suited for the control of these systems, due to the lack of sensor data. We are currently investigating the potential of a non-model-based learning strategy, Reinforcement Learning (RL), in dealing with this kind of discrete sensor information. Here, we describe ongoing experiments with a wet clutch, which has to be engaged smoothly yet quickly, without any feedback on piston position.
