摘要
考虑由载体和机械臂组成的空间机器人系统的协调控制问题,提出了一种新的协调控制策略.该策略首先利用简单的变结构控制器粗略控制载体的运动,进而设计机械臂控制器以保证手端精确跟踪其期望的运动轨迹.应用该策略分别对手端自由运动和受限运动设计了相应的控制器,并对两杆平面空间机器人系统进行了仿真,证实了控制策略的有效性.
The coordinated motion control of manipulator/spacecraft system is investigated in this paper. A new coordinated control scheme is proposed, in which the motion of the spacecraft is controlled using a simple variable structure control scheme and the manipulator is controlled to track the desired end effector trajectory. The proposed scheme is applied to the controller design of free motion and constrained motion of the manipulator′s end effector. A two link planar space robot system is simulated to verify the effectiveness of the control scheme.
