由于主动控制中广泛使用的自适应滤波 - x L MS算法只适用于线性控制问题 ,针对一些非线性问题 ,本文提出利用一种非线性自适应滤波方法——基于模糊逻辑系统的自适应滤波方法来解决一类参考信号与外扰呈非线性函数关系的前馈主动控制问题。仿真结果表明 ,该模糊自适应滤波器优于线性滤波器的控制效果
Because the adaptive filtering-x L MS algorithm widely used in active control is only suitable for linear control problems, this paper proposes a nonlinear adaptive filtering method based on fuzzy logic system adaptive filtering for some nonlinear problems To solve a class of reference signal and external disturbance showed a nonlinear function of the feedforward control problem. The simulation results show that the fuzzy adaptive filter is better than the linear filter
