相对运动小推力的模糊控制

Low Thrust Fuzzy Control in Relative Motion

在航天器交会对接和轨道保持问题中 ,一般都基于相对运动方程进行控制 ,然而在某些情况下 ,用极大值原理有时并不能求得问题的解 ,而且对控制屡有噪声干扰时 ,控制律难以设计 ,该文讨论了在相对运动方程下对追踪飞行器进行模糊控制的方法。文中提出基于模糊逻辑规则构造控制器。仿真结果验证了模糊控制器的可行性 ,而且验证了在噪声干扰下控制器的鲁棒性。

Relative motion is applied to rendezvous and station keeping of spacecrafts, However there is no solution in some cases using Pontryagin maximum value principle, especially when the control law is subject to noise. This paper discusses how to design fuzzy controllers of chasing spacecraft in relative motion., Fuzzy controllers are designed using fuzzy logic, and simulation results illustrate the feasibility and robustness of the controllers.
