| 摘 要： | 为了改善基于陀螺平台的摆式列车检测系统的动态特性，用最小二乘法及其改进算法，建立了描述陀螺平台系统动态特性的差分数学模型，并对其动态特性进行了分析．在此基础上，采用零极点匹配法设计了相应的动态补偿数字滤波器．仿真结果表明，用所设计的数字滤渡密对陀螺平台系统进行动态补偿，能使超高信号的延时小于0．4s，满足摆式列车实时倾摆控制的需要．

| Abstract: | To improve the dynamic characteristics of the monitoring system of a tilting train based on a single-axis gyroscope platform, a difference model to describe the dynamic characteristics of gyroscope platforms was established with the least squares method and its improved algorithms, and the dynamic characteristics of a gyroscope platform were analyzed. The corresponding dynamic compensation digital filters were designed with the zero-pole matching method. The simulation result shows that the delay time of superelevation signals is less than 0.4 s with the designed digital filters to meet the needs of real-time tilting control of tilting trains. |
