The invention discloses a three-axis air bearing table and a simulation test anti-toppling control method thereof.The three-axis air bearing table is internally provided with an anti-toppling protection device, in the anti-toppling control method, a first angle, a second angle and a first angular velocity are preset, and the real-time angle and the real-time angular velocity of the three-axis air bearing table in the process of executing a simulation test task are collected; the real-time angle and the real-time angular velocity are compared with the preset angle and the preset angular velocity respectively, when it is judged that the three-axis air bearing table has the toppling risk, the risk avoiding operation is conducted by adopting a control method combining urgent risk avoiding control and normal risk avoiding control, and the risk avoiding operation is conducted by adopting a method combining mechanical protection and software control protection. And the working reliability of the three-axis air bearing table can be further improved.
本发明公开了一种三轴气浮台及其仿真测试防倾倒控制方法,三轴气浮台中设有防倾倒保护装置,防倾倒控制方法中预设第一角度、第二角度和第一角速度,采集三轴气浮台在执行仿真测试任务过程中的实时角度和实时角速度,并将实时角度和实时角速度分别与预设的角度和角速度比较,当判断三轴气浮台具有倾倒风险时,采用紧急避险控制和正常避险控制相结合的控制方法,做出避险操作,通过机械防护和软件控制防护相结合的方法,可进一步提高三轴气浮台的工作可靠性。
