摘要
对天棚阻尼器方法的SISO(单输入输出)调节器与集中式调节器进行了比较,结合天棚阻尼、动态补偿、滑模控制方法,对执行器非线性进行了优化研究。计算分析结果表明:对半主动执行器性能进行有限的限制,集中式调节器可以得到最优控制力,将会最大限度地减少车体加速度。仿真结果表明:采用混合控制方法,可以更好地提高铁路车辆性能方面的动态稳定性和舒适性。
The ceiling damper method SISO（single input/output） regulator and centralized controller were compared.Combining with skyhook damping,dynamic compensation,sliding mode control method for the actuator,nonlinear behavior were researched.Calculation results showed that the semi active actuator performance was limited by constraints,centralized regulator could get optimal control force for minimizing the vehicle acceleration.The simulation results showed that hybrid control method could improve the performance of railway vehicle dynamic stability.
