摘　　要：针对数控机床轴运动过程中存在的多种非线性问题,在基于滑动控制原理的基础上,提出了一种具有参数自整定能力的模糊滑模控制方法。仿真结果表明,该方法执行效率高,稳态误差小,能够消除数控机床轴控制系统中多种非线性特性所引起的副作用,具有较好的鲁棒性和较高的控制精度,是一种有效的控制方法。Aiming at problem of multiple kinds of nonlinearities in the motion of machine tool axis, a design method of fuzzy sliding mode controller with self-tuning capability is presented based on slide-mode control theory. The results of simulation show that the method can implement efficiently and get low steady-state error. At the same time, it can eliminate the negative effects of the numerical control machine tool axis control system caused by multiple kinds of nonlinearities, has good robustness and high accuracy. So it provides a solution to the problem of nonlinearity of servo systems.
