The paper details a machine learning-based framework for testing space docking mechanisms, emphasizing rapid deployment and cost-effectiveness. It covers mathematical modeling, stability analysis, and a novel automatic calibration method for gravity compensation parameters using multiple linear regression. The core innovation lies in using a Backpropagation (BP) neural network to derive mechanical characteristics from comprehensive sensor data.
The study integrates a BP neural network to extract mechanical characteristic test results, building on established theoretical foundations. For gravity compensation parameter optimization, multiple linear regression (MLR) is employed due to its interpretability. Advanced MLR techniques like Lasso and Elastic Net are referenced for robust modeling, especially in high-dimensional data, ensuring precision and reliability in complex operational conditions.
A novel testing platform is constructed utilizing a six-degree-of-freedom industrial robotic arm and a three-dimensional force and torque sensor. This setup is designed to control 3D force, torque, and position, enabling comprehensive mechanical characterization. It features automated calibration of gravity compensation parameters and leverages event-triggered control approaches to enhance stability and adaptability for diverse docking mechanism tests.
