摘要
针对数控机床位置伺服系统参数不确定及存在外界干扰的特点,将小脑模型关节控制器(CMAC)与滑模控制相结合,设计了基于CMAC的神经元离散滑模制系统及其控制算法。仿真结果表明,该控制方法不但大大降低了普通滑模变结构控制中的抖振,而且具有良好的动静态特性及较强的鲁棒性。
A nerve cell discrete sliding mode control system based on CMAC (cerebella model articulation control) and its control method was proposed for NC Machining Tool position servo system with uncertain parameters and external disturbance, which was composed of CMAC and sliding mode control. The simulation results show the control method effectively reduces the chattering in the conventional slide mode variable structure control, and has better dynamic performance, static performance and strong robustness.
