【摘要】 五自由度模拟靶台是惯性约束聚变靶室里的预对准定位系统（简称 Ａ Ａ Ｐ），是一种空间定心的闭环控制运动体系。整台装置拟安装在直径 ３～４ｍ ，１．４×１０－ ４ Ｐａ 的高真空度的铝金属大球体内。该系统采用多处理机并行处理技术，计算机经由光栅位移传感器实现空间五维工件台的闭环控制， 靶心位置的综合定位误差 σｉ＝±２．２７μｍ 。更多还原

【Abstract】 A five freedom simulating target table is a prepositioning system situated in the target chamber of the inertial confinement fusion.It is a closed loop control moving system centered in the space.The whole unit will be installed within a large sized aluminum sphere with a diameter of 3~4m and a high vacuum degree of 1.4×10 -4 Pa.The parallel processing technique with multi processor is applied to the system.The closed loop control for the spatial five freedom positioning table is carried out by the computer via grating displacement sensor.A comprehensive positioning error σ i at the target central position is ±2.27μm.更多还原
