摘　　要：对天棚阻尼控制器及补偿滤波控制器算法在铁道车辆主动悬挂中的应用进行了研究。研究表明,当轨道不平顺输入包含有确定性方向不平顺信号时,如爬坡及曲线通过时,采用天棚阻尼控制器算法将会产生不可恢复的悬挂位移,这将影响车辆的运行平稳性,甚至会给行车安全带来隐患。当加入补偿滤波器后,构成补偿滤波器控制算法。仿真分析表明,该算法克服了天棚阻尼控制器的缺点,更具实用价值。Application of skyhook and complementary controller in railway vehicle active suspension is studied. Research showed that when the track include deterministic input signals, skyhook controller algorithm will produce unrestored deflection in second suspension, which will deteriorate the ride quality or even imperil the runing safety. When complementary filter added, the complementary algorithm controller is formulated. Simulation results showed that this algorithm is more applicable than skyhook controller.
