摘要

针对欠驱动双连杆机器人的控制问题,提出了一种改进的模糊控制方案。所提出的模糊控制器对杂技演员的直立姿态进行稳定和平衡。首先设计了线性二次型调节器(LQR)用于控制目的。采用LQR尺度增益设计模糊控制器。通过仿真研究,验证了所提模糊系统的有效性。仿真结果表明,非线性模糊控制器能较好地调节摆动运动,保证系统的全局稳定性。

Control of under-actuated two-link ROBOT with Linear Quadratic Regulator and fuzzy controller
This paper focuses on improved version of fuzzy control arrangement, for control of under-actuated two-link ROBOT. The proposed fuzzy controller stabilizes and balances the acrobat in erect position. A Linear Quadratic Regulator (LQR) was first designed for controlling purpose. LQR scaling gains were incorporated to design the fuzzy logic controller. The efficiency of the proposed fuzzy system is established through simulation studies. The simulation results have demonstrated that nonlinear fuzzy controller achieves much better regulation of the desired swing motion and guaranties global stability.
