摘要

通过利用二阶低通滤波器(LPF)对动态滑动面进行建模，形成等效动力学的频率特性，设计了频率型二阶滑模(FS2SM)控制器。通过对一辆内置主动液压互联悬架(HIS)系统的半车模型(HCM)的仿真，验证了该方法的有效性。闭环性能证实，在控制方案中加入适当的滤波器不仅可以减小滚转角，而且可以塑造其频谱。

Frequency-Shaped Second-Order Sliding Mode Control for Smart Suspension Systems

Design of a frequency-shaped second-order sliding mode (FS2SM) controller is demonstrated by means of exploiting second-order low-pass filter (LPF) to model the dynamic sliding surface to shape the frequency characteristics of the equivalent dynamics. The proposed technique is numerically verified in the simulation of a half-car model (HCM) with inbuilt active hydraulically interconnected suspension (HIS) system. The closed-loop performances confirm that inclusion of an appropriate filter in the control scheme allows not only to reduce the roll angle but also its spectrum can be shaped.
