| Summary: | 碩士 === 國立交通大學 === 電機與控制工程系所 === 92 === Implementing the controller in an ANC (Active Noise Cancellation) headset using analog circuit has the drawback of parameter matching difficulties. Secondly, it is also hard to implement a high-order contoller in analog circuit. When the performance optimization is necessary, the contribution of this thesis is to implement the controller for ANC headset system digitally using the DSK5510 DSP processor and establish an experimental platform which speeds up the development process.
This thesis can be divided into two parts：the first part is a brief introduction of the ANC theorem and its historical review. It also describes the structure, constraints and simulation results of the ANC system designed by the optimal control methods. The 2nd part of the thesis shows the implementation proceduce by DSK5510 and establishment of a platform with the advantages: programmable, achieving complex algorisms, high order and low power consumption.
