摘　　要：详细推导了基于虚拟传感器的有源噪声控制系统的算法结构。在TMS320C6727硬件平台上,采用LMS算法完成了误差通道模型的传函辨识,用FXLMS算法对虚拟传感器的系统性能进行了试验分析。试验结果表明,该方法可以有效地将噪声控制范围向虚拟传感器处转移。An active noise control algorithm architecture based on virtual sensor is derivate in detail_ The error path models are identified using LMS algorithm and the performance of virtual sensor system are analyzed employing FXLMS algorithm on the TMS320C6727 platform The experimental results show that the virtual sensor based on active noise control algorithm can effectively move the control field to the virtual sensor.
