针对具有液体晃动和太阳帆板挠性振动的变质量卫星的姿态控制问题,文章提出一种用逻辑微分构造广义对象的方法。在此基础上构造全系数自适应控制方案。文中采用平均法分析了逻辑微分的机理,采用描述函数法分析了为抑制常值干扰而引入的逻辑积分的性质,最后通过液体远地点发动机工作期间卫星姿态的自适应控制系统仿真验证了文中提出的控制方案的有效性。 Aiming at the problem of attitude control of variable mass satellites with liquid sloshing and solar flexible vibration, a method of constructing generalized objects by using logical differentiation is proposed. Based on this, a full-coefficient adaptive control scheme is constructed. In this paper, the averaging method is used to analyze the mechanism of logic differential. The description function method is used to analyze the nature of the logic integral introduced to suppress the constant value interference. Finally, the proposed control scheme of the satellite attitude during aero- Control the effectiveness of the program.
