Inverse Differential Riccati Equation to Optimized Human-Robot Collaboration

Hamed Rahimi Nohooji, Holger Voos

This paper presents a framework for human-robot collaboration that integrates optimal trajectory generation with a robust tracking control strategy. The proposed framework leverages the inverse differential Riccati equation to optimize the collaboration dynamics, providing an efficient method to generate time-varying, task-specific trajectories for the human-robot system. To ensure the accurate tracking of these trajectories, a neuro-adaptive PID control method is implemented, capable of compensating for system uncertainties and variations. This control strategy dynamically adjusts the PID gains using a radial basis function neural network, ensuring both stability and adaptability. Simulations demonstrate the method's effectiveness in achieving optimized human-robot collaboration and accurate joint-space tracking, making it suitable for real-world applications.
