Robust Control of Pantograph–Catenary Contact Force Under High Disturbance: A Comparative Study

Journal of Information Systems Engineering and Management
This paper presents a comparative study of three control strategies for regulating the contact force in pantograph–catenary systems operating under high disturbances and nonlinear dynamics. A high-fidelity multi-layer physical model is developed to capture key system behaviors, including severe catenary oscillations and variations in pantograph mass ...
