This paper presents an optimized sliding mode controller (OPSMC) for vibration control of active suspension systems. The proposed controller consists of two parts: the first is the fast terminal sliding mode controller which performs fast convergence, and the second is the particle swarm optimization algorithm which is used to achieve the optimal controller’s’ parameters. The merit of OPSMC has quite simple structure and easy to be regulated, as well as improve the tracking performance. The half-car active suspension systems with non-linearity such as the parameters variation and external disturbance are simultaneously taken into account to provide a realistic framework. The control objective is to deal with the classical conflict between minimizing vertical and angular chassis accelerations to increase the ride comfort. Versus, to keep minimum dynamic wheel loads and suspension deflections to ensure the ride safety. Finally, to show the performance of the proposed OPSMC, the comparison with a recently developed efficient method called optimization and static output-feedback control (OPSOFC) is conducted with different roads disturbances.

半车式主动悬架系统的优化快速终端滑模控制

本文提出了一种用于主动悬架系统振动控制的优化滑模控制器（OPSMC）。所提出的控制器包括两部分：第一部分是执行快速收敛的快速终端滑模控制器，第二部分是用于获得最佳控制器参数的粒子群优化算法。OPSMC的优点是结构简单，易于调节，并提高了跟踪性能。同时考虑了具有非线性（例如参数变化和外部干扰）的半车主动悬架系统，以提供一个现实的框架。控制目标是解决最小化垂直和角向底盘加速度以增加乘坐舒适性之间的经典冲突。与，保持最小的动态车轮载荷和悬架挠度，以确保行驶安全。最后，为了显示所提出的OPSMC的性能，在不同的道路干扰情况下，与最近开发的称为优化和静态输出反馈控制（OPSOFC）的有效方法进行了比较。
