摘要
针对高速列车高速行驶时列车车体横向振动,文章提出了基于LQG控制算法。在SIMPACK中建立高速列车17自由度横向振动模型,结合MATLAB/Simulink进行仿真分析,分别从时、频域分析LQG控制对车辆运行平稳性的影响。结果表明,LQG控制可提高列车运行横向平稳性,车体横向振动加速度在人体敏感0.1~2 Hz频率范围内也有一定改善。
Aiming at the lateral vibration of the train body when the high-speed train is running at high speed,a control algorithm based on LQG was proposed.A 17-degree-of-freedom lateral vibration model of a high-speed train was built using SIMPACKandthe MATLAB/Simulink was used for simulation analysis.The influence of LQG control on vehicle running stability was analyzed from time and frequency domains.The results showed that LQG control couldimprove the lateral vibration acceleration of train operation,and the lateral vibration acceleration of train body couldalso be improved in the frequency range of 0.1~2 Hz.
