| 摘 要： | 小波变换具有在时域和频良好的局部化性质，对干扰信号具有滤波的作用。采用小波变换的地系统的输出量进行滤设计广义预测控制器，仿真结果表明，该方法抗噪声能力强，在控制器性能得到改善的情况下，可得到较平滑输入曲线。

| Abstract: | Wavelet has the good feature of locallization in time-domain and frequency-domain,and can be used as filter.This paper uses non-linear de-noising of wavelet transform to filter the input and output of the design of the general predictive controller.The simulation results show that the method presented improve the control performance with much more smoother control action when there is big noise or lower model dimension.Further,it is robust to the unmodelled erro.The method may be useful in practice. |

| Keywords: | Wavelet transform Non-linear de-noising Generalized predictive control Adaptive Roubustness |
