AI Technical Summary
The existing underground monorail control system lacks the ability to anticipate road conditions ahead and cannot adaptively adjust speed and drive commands, making it prone to loss of control under complex working conditions, affecting transportation efficiency and equipment lifespan.
A predictive control method based on digital track spectrum is adopted. By acquiring the locomotive position and track spectrum, the mass and rail surface adhesion coefficient are identified in real time, the speed is dynamically corrected, and torque commands are generated by combining super-helical sliding mode feedback control to achieve precise speed regulation and smooth operation.
It effectively avoids emergency braking caused by speed loss, improves operational stability and safety, extends the life of key components, and improves transportation efficiency.
