The invention relates to a gravity unloading controller for a Lorentz force magnetic suspension universal stabilized platform. The system mainly comprises an upper computer PC, a lower computer FPGA, a program-controlled direct-current power supply, a photoelectric encoder, a linear displacement sensor, an AD conversion module and a Lorentz force magnetic suspension universal stable platform. When the gravity center changes due to attitude movement of the platform load cabin, the photoelectric encoder measures angle displacement information and sends the angle displacement information to the lower computer FPGA, the lower computer FPGA packs data signals and sends the data signals to the upper computer PC, the upper computer PC calculates the magnitude of current needing to balance unloading gravity and then sends an instruction to the program-controlled direct-current power supply, and the program-controlled direct-current power supply controls the program-controlled direct-current power supply to balance unloading gravity. The program-controlled direct-current power supply further adjusts the current of the magnetic bearing coil, and gravity unloading of the platform load cabin in any posture is achieved. The invention belongs to the field of spaceflight, can simulate a space weightless environment on the ground, and supports research breakthrough and demonstration verification of a floating body type spacecraft attitude control technology such as a Lorentz force magnetic suspension satellite.

    本发明涉及了一种洛伦兹力磁悬浮万向稳定平台重力卸载控制器。主要组成包括:上位机PC、下位机FPGA、程控直流电源、光电码盘、线位移传感器、AD转换模块,以及洛伦兹力磁悬浮万向稳定平台。当平台载荷舱姿态运动导致重心发生变化时,光电码盘测出角度位移信息发送给下位机FPGA,下位机FPGA将数据信号打包发送至上位机PC,上位机PC计算出需要平衡卸载重力的电流大小,然后发送指令给程控直流电源,程控直流电源进而调节磁轴承线圈电流大小,实现平台载荷舱任意姿态下的重力卸载。本发明属于航天领域,可在地面模拟太空失重环境,支撑洛伦兹力磁悬浮卫星等浮体式航天器姿态控制技术的研究攻关和演示验证。
