摘要
提出一种基于实型遗传算法的抽头延迟线滤波器 (横向滤波器 )设计方法 ,通过对连续空间遗传算法的改进 ,将其运用到动态系统的自适应逆控制中。对象和逆控制器各用一个抽头延迟线滤波器表示 ,用抖动方法给对象建模 ;为使对象模型的逆的自适应过程能及时跟上对象模型的变化而无滞后 ,采用离线过程进行模型参考逆模型的训练。最后给出一个已镇定非最小相位对象的模型及其模型参考逆的仿真结果 ,验证了方法的有效性。
A design method of tapped delay line filter (transversal filter) based on real genetic algorithm isproposed.Byimprovingcontinuousspace genetic algorithms, it is applied in the adaptive inverse controlofdynamicsystem.Plant and inverse controller are expressed by a tapped delay line filter respectively. In order to make the inverse adaptive process of plant model change with the plant model timely and without lag, the model reference inverse model is trained offline. Finally, the effectiveness of this method is demonstrated by simulation result of a stabilized non minimum phase plant model and model reference inverse.
