摘要
针对空间飞行器大角度姿态机动控制具有非线性,并要求控制器具有较高的指向精度、姿态稳定度及鲁棒性等特点,应用P-FUZZY-PID复合控制算法,建立了±180°内的模糊规则库,设计了飞行器姿态控制器;系统采用DSP作为星载控制器,光纤陀螺作为姿态敏感器,反作用飞轮作为执行机构,系统程序采用C语言编程,利用单轴气浮仿真实验台实现了物理仿真实验;实验结果证明该控制方法不仅能实现飞行器大角度机动控制,机动响应快,还表现出较好的鲁棒性。
Nonlinearity is the feature of the spacecraft with a large angle maneuver control. And the controller is necessarily provided with high pointing precision, satellite attitudes stability, robustness, etc. The author uses the analysis of P-FUZZY-PID composite control algorithm to establish fuzzy rules and design the spacecraft attitude controller. DSP is adopted as the On-Board Controller, the fiberoptic gyroscope is used as the attitude sensor and the reaction wheels is used as the Actuator. At the same time, In C language environment, the air flotation test table was utilized to accomplish the physical simulation. The result testified that this method can accomplish the control ling of the large angle maneuver; it can also accelerate the maneuver＇s response as well. In addition, the robustness is perfectly shown in the test.
