以仿人机器人为研究对象，着重设计了三个自由度的机器人手臂控制系统。首先采用Ｄ－H和齐次变换矩阵建立了机器人运动学模型，推导出了机器人运动学方程正、逆解的表达式。利用matlab编程和simulink仿真分析了机器人控制系统的性能，得到的运动曲线可为机器人的工作规划和仿人机器人整机控制提供参考。(Taking humanoid robot as the research object, three degrees of freedom robot arm control system is designed. Firstly, the kinematics model of robot is established by using D H and homogeneous transformation matrix, and the expression of Fang Chengzheng and inverse solution of robot kinematics is derived. The performance of the robot control system is analyzed by MATLAB programming and Simulink simulation. The obtained motion curve can provide reference for the robot's work planning and humanoid robot control.)
