摘　　要：文章考虑液压悬置和电磁线圈作动器的耦合,建立三缸发动机主动悬置动力学模型。针对传统PID控制无法同时消除1阶和1.5阶2个主要阶次的振动问题,设计了滑模变结构主动悬置控制器,使用易于测量的线圈电流作为反馈,构造了全维状态观测器。In this paper, a dynamic model of an active mount for the three - cylinder engine is established, which considering the coupling of hydraulic mount system and the electromagnetic coil ac- tuator. As for the incapability of attenuation of both the 1st -order and 1.5th -order vibration at the same time when using the traditional control strategy, a sliding - mode variable structure control strate- gy is employed to provide control input to system, and a full state observer is constructed.
