| 摘 要： | 动量轮是所有三轴稳定卫星姿态控制的主要和关键部件。由于微小卫星本身的转动惯量很小，微弱的非控制力矩都有可能导致整个卫星失控，因此对其动量轮控制器提出了无超调、超短响应时间、零稳态误差的理想设计要求，传统的PI控制器无法同时满足这些要求。提出了一种基于非线性模糊控制理论的模糊控制器，并给出了一个具体的设计实例，其仿真结果表明：这种控制器可以同时达到零超调、超小稳态误差(0．004％)、超短响应时间(小于1．5s)等设计要求，十分逼近动量轮的理想设计要求。

| Abstract: | The Momentum Wheel is the main and key component of attitude control system in all three-axis stabilization satellites. Because the inertia of the micro-satellite itself is very small and any weak non-control moment may make the satellite out of control, an ideal design for the momentum wheel is requested to meet the demands of none overshoot, short response time, and zero steady error simultaneously. The traditional PI controller cannot meet all the demands at the same time. A fuzzy controller based on nonlinear fuzzy control theory is therefore presented, and a design example is discussed in detail. The simulation results of the design example show that this controller can simultaneously meet all the demands of zero overshoot, ultra small steady error (0.004%) and ultra short response time (less than 1.5s), which is very close to the ideal design request. |
