Abstract:
A Motion Cueing Algorithm (MCA) based on Model Predictive Control (MPC) plans a simulator trajectory that optimally satisfies a user-defined cost function, whilst not exceeding the simulator limits, given a prediction of the future specific forces and rotational rates (inertial signals). Model Predictive Motion Cueing Algorithms (MPMCAs) have important advantages over filter-based MCAs, e.g., they allow for zero phase distortion filtering. It is, however, not clear how the inertial signals should be predicted and how accurate the prediction needs to be to obtain an acceptable quality of perceived motion. Furthermore, it is not clear how to prevent discrepancies in the predicted inertial signals to cause large false or missing cues. This paper presents a simple online prediction method and demonstrates how the state-error term of the cost function can be used to reduce the negative effects of prediction errors. The results of a human-in-the-loop experiment are encouraging and informative for further improvement of the method.
