Automatic Fault-Tolerant Control Method for the Active Tilting Control System of Pantograph in Tilting Electric Multiple Unit at Actuator Faults
摘要
Abstract
The state equation and actuator model under partial fault was established through analyzing the structure and the working principle of active tilting control system of pantograph in tilting Electric Multiple Unit (EMU). Considering the uncertainties of tilting control system parameters and actuator faults, a-daptive fault-tolerant control strategy based on the reference model was adopted to restructure the driving force of actuator by equally allocating the loss driving force of fault actuator to other normal actuators. An example was given for the active tilting control system of pantograph with actuator faults in certain tilting EMU, and simulation was carried out on fault-tolerant control when EMU running at the speed of 120 km ? H-1 through a circular curve with the radius of 800 m. Results show that the tilting control system can track a given parameter output and make state tracking error converge quickly to 0. The restructuring of actuator driving force is effective after partial actuator faults by using an adaptive failure compensation controller based on the technology of adaptive fault-tolerant control, which shows that the proposed adaptive fault-tolerant control method is fully applicable to the uncertain running environment for the active tilting control system of pantograph in tilting EMUs.关键词
