A feedforward neural network (FFN) was developed and trained using data from a commercial multibody software to predict unknown masses with high accuracy (98.5%). The study achieved promising results, with the FFN effectively predicting payload not included in the training set with minimal error. The findings suggest future research directions, including the estimation of variable payload and the use of automated hyperparameter tuning and comparing with extended Kalman filters, to enhance the AI-based control and maintenance of complex systems. Further investigations are needed to compare these AI methods with traditional model-based controllers.
