基于功率调度的在线建模自适应反馈控制系统的研究

自适应有源噪声控制是噪声控制中的一项先进技术。使用附加噪声建模的自适应控制系统会增加输出的残留噪声，而且还可能造成反馈控制系统发散。功率调度方法可以有效地减小残留噪声，增加系统的鲁棒性。根据是否使用功率调度方法，对2种在线次路径建模自适应反馈控制系统进行了研究，仿真结果表明采用功率调度方法的自适应反馈系统比不使用功率调度方法的反馈系统具有更好的降噪效果。

Study on Adaptive Feedback Control System Online Modeling Based on Power Scheduling

Adaptive technique of active noise control is an advanced technique. Adaptive control system using auxiliary noise will increase the residual noise of the output, and lead feedback control system to diverge. Power scheduling strategy can effectively reduce residual noise, and increase the robustness of the system. According to whether the feedback control system using online secondary path modeling method uses power scheduling strategy, some research was done. Simulation results show that adaptive feedback control system using power scheduling strategy presents better performance than adaptive feedback control system not using power scheduling strategy.
