采用模糊/PID混合控制技术,对自主交会逼近段的轨道控制进行了研究.将逼近段轨道控制解耦为三个独立通道的控制,并分别设计了逼近段轨道控制的模糊控制器、PID控制器和模糊/PID混合控制器.在考虑导航和控制误差情况下,对模糊控制器、PID控制器和模糊/PID混合控制器的轨道控制情况进行了数值仿真,并对三种控制器的轨道稳定性和燃料消耗情况进行了比较.仿真结果表明,模糊/PID混合控制器的最后逼近相对运动轨迹比模糊控制器更稳定,同时燃料消耗更少.

The trajectory control of final approach in autonomous rendezvous is studied based on fuzzy/PID hybrid control. The problem of final approach trajectory control is divided into three independent control channels, the fuzzy controller, PID controller and fuzzy/PID hybrid controller are designed respectively for each channel. Considering errors of navigation and control, numerical simulations are undertaken to verify the efficiency of the fuzzy controllers, the PID controller and the fuzzy/PID hybrid controller, and their performances are compared in terms of trajectory stability and propellant cost. It is shown that the fuzzy/PID hybrid controller can guarantee the more stable trajectory approaching with less propellant consumption.
