| 摘 要： | 根据高速探伤需要,为超声波探头设计了抗蛇行运动和垂向振动的电液伺服系统来保证探头与钢轨相对位置保持不变,为实时探伤提供了可靠的保障。该系统已达到设计要求,目前已装车在环铁实验。但由于现场工况复杂,有必要引入前馈控制来进一步提高跟踪性能。本文针对自适应零相位控制算法,进行了数值仿真计算,以备在实际中应用。

| Abstract: | In order to meet the needs of high-speed track inspection cars,the electro-hydraulic servo system is designed for the ultrasonic detector heads to resist sinusoidal movement and vertical vibration,maintain invariable relative positions between detector heads and rails,and provide reliable guarantee for real-time detection.The system has fulfilled the designing requirements and has been installed on board for tests on the Ring Railway.Due to the complex working conditions on site,feedforward control needs to be introduce into promote tracking performance.Numerical simulation is made on the basis of the Adaptive Zero Phase Error Tracking Control(ZPETC) Algorithm in preparation for application in practice. |
