And the result is mainly arose from the simple structure of PID controller which decide the limitation of control quality when used to application, and it also results in bad performance when it is used to long time delayed system and un-stable object. For the same reason, PID controller just determines few zero and pole points which also lead to not so good control quality of the closed loop.
这主要是因为PID控制器结构上的简单性决定了它在控制品质上的局限性，并且这种简单性使得PID控制器对大时滞、不稳对象等被控对象的控制性能不是很好；同样，PID控制器只能确定闭环系统的少数零极点，无法得到更好的闭环控制品质；此外，PID控制器无法同时满足对设定值跟踪和抑制外扰的不同性能要求。

Based on analyzing the biological structure and function of biology nervous system, the paper presents a modularized distributed hierarchical control technology to real-time control the hexapod walking bio-robot, using the wavelet-based neuro-fuzzy networks method at the simulation of the locomotion control. The Matlab simulation results show that robot locomotion follow track is almost identical with the desired curve. The error curve is quickly rapid convergent, and the static error is almost approximate to zero. So it gets over the difficulty of traditional control theory that is difficult to set up the controlled object model and worse adaptive capacity, and the robot control system has the advantages of high static and dynamic performance, strong anti-disturb ability and robustness. The research has established foundation to further perfect the robot locomotion function.
