针对并联机器人结构复杂、控制精度要求高的特点,首先对一种新型6-PSS并联机器人进行了运动学分析,然后根据神经内分泌调节原理和抽象出的二种内分泌调节的反馈机制,设计了一种新型的智能控制器,并给出了其调节规律。该控制器结构上遵循内分泌调节模型,策略上遵循内分泌规律。通过仿真实验证明了神经内分泌智能控制器在快速性、稳定性上均优于PID控制器,该控制方法为机器人的复杂控制提出了一种新思路。
parallel robot has a complex structure and high requirement in control precision. In this paper, the kinematics of a novel 6-PSS parallel manipulator is firstly analyzed. Then according to the bormone modulation and two feedback modulation models of neuroendocrine system, a new intelligent controller with its modulation rules is designed. The controller has the same structure with neuroendocrine system and its strategy follows hormone modulation hill function. The simulation result shows that the controller is better than PID controller. The proposed control method may be a new way for robot control.
