【摘要】 为提高6自由度液压振动台的控制精度,详细分析振动台系统的伺服控制原理并给出具体的实现方式。采用自由度合成及分解矩阵实现振动台的自由度独立控制。采用三状态控制器提高振动台系统加速度响应频宽,增强系统稳定性,并给出了控制器参数的计算公式。采用压力镇定控制器削弱系统中各激振器间的内力耦合,减小能量内耗。文末通过试验验证了6自由度振动台伺服控制策略的有效性。更多还原

【Abstract】 The servo control strategy of 6 DOF vibration table are presented to improve the control precision of vibration test. DOF composition and decomposition controller is used to realize the DOF control mode. The acceleration frequency band and the stability of the system are improved with three variable controllers and the formula of the controller parameters are presented. The force balance controller is used to reduce the inner force among the 8 actuators. The test results verify the validity of servo control strategy of 6 DOF vibration table.更多还原
