线性开关磁阻执行器（LSRA）在汽车悬架系统等高力线性应用中具有很大的应用潜力。在本研究中，建立了一个电控主动悬架系统。根据运动要求，采用双向功率放大器为直线执行器供电并吸收其产生的能量。线性运动是通过收缩和伸展LSRA来完成的。针对已建立的电磁悬架系统，提出了一种实时控制算法。研究了带自适应机构的滑模技术来补偿系统的非线性和外部道路轮廓。在实验室进行了实验，以证明所提出的主动悬架系统的高性能。
Linear switched reluctance actuator (LSRA) is of great potential using in kind of high-force linear applications such as automotive suspension system. In this study, an electrical controlled active suspension system is built. Bi-directional power amplifier is used to supply power to and absorb generated energy from linear actuator based on the movement requirement. The linear motions are accomplished by retracting and extending the LSRA. With regard to the established electromagnetic suspension system, a real-time control algorithm is developed. Sliding model technique with adaptive mechanism is studied to compensate the system non-linearities and external road profile. Experiments are conducted at the laboratory to present the high performance of proposed active suspension system.
