基于CMAC网络的滑模位置控制研究

机床数控系统的位置伺服控制模块是一个典型的非线性、不确定性的时变系统，传统的PID控制方法和自适应控制不能达到满意的控制效果。将CMAC网络与滑模变结构控制相结合，提出基于CMAC的滑模位置控制策略，并对该控制算法进行了仿真研究。结果表明：位置伺服系统在该控制策略作用下，响应速度快，无超调，并且能大大减弱常规滑模变结构控制中的抖振现象。

Research of neuron sliding mode position control based on CMAC

Aiming at uncertain parameters and external disturbance of Numerical Control (NC) Machining Tool position servo system, this paper proposed a kind of neuron sliding mode control algorithm based on CMAC (cerebella model articulation control) by combing CMAC network with sliding mode control. The simulation results show the control method effectively reduces the chattering phenomenon in the conventional slide mode variable structure control. It also shows the position servo system has better dynamic performance, static performance and strong robustness. It can realize rapid and exact position servo control.
