一种自动仿型铣床的自适应控制器

Adaptive controller for automatic profiling machines

针对一类参数变化幅度大 ,过渡过程频繁的运动系统 ,提出了一种实用的自适应控制器方案 .基于这种结构简单 ,鲁棒性强 ,约束条件较少的方案 ,为一种自动仿型铣床设计了自适应速度控制器 .数字仿真表明 ,自适应调速系统的性能能够满足设计要求 .将仿真结果应用在某实际仿型铣床的控制器上 。

A practical adaptive controlling scheme is proposed for the movement system which has a high degree of (parameter) variation and high frequency of transient process.Based on such a scheme,simple in structure,high in robustness and small in constraint condition,an adaptive speed controller has been designed for automatic profiling machines.The digital simulation has showed that the adaptive speed-governing system can satisfy the design needs.Applied the simulation result to a profiling machine,it is proved to produce the same result in reality.
