| 摘 要： | 由于广义预测控制器依赖于表征过程的线性模型,没有考虑未建模误差的影响,随着预测长度的增加,其预测误差也增大.因此,提出用小波网络建立误差的预测模型,并对模型预测进行动态补偿,以抑制模型失配的影响,增强鲁棒性.仿真结果表明了算法的有效性.

| Abstract: | Generalized predictive control relies on the process linear model and doesn't consider the effect of unmodelled error. With a longer prediction length, the prediction error becomes greater. Therefore this paper presents an error prediction model using wavelet network and uses it to compensate the error dynamically. The adjusted GPC can reduce the influnce of unmodelling section and enhance its robustness. The simulation results have shown the method's validity. |

| Keywords: | Wavelet network predictive control model mismatch robustness. |
