摘　　要：针对两通道座椅安全带固定点试验设备进行控制策略研究。设备龙门框架结构,作动器电动控制,方便试验时位置调整。控制系统硬件部分进行自主研发PID闭环伺服控制器,具备力控和位控两种模式且可进行无扰动切换。软件部分开发实时补偿自适应控制算法,满足试验过程中试件刚度变化时系统快速跟踪响应性能。Control strategy is studied for two channel fixed point test-bed of seat belt. Frame structure is adopted,actuator is electric controlled and easy to adjust position of the test. PID closed-loop servo controller of the hardware part is independently developed,which has two modes of force control and position control. Real-time compensation adaptive control algorithm of the software part is developed,to meet fast tracking response performance of the system when the seat stiffness changes during the test process.
