An adaptive current control technique for active filters
説明
An active filter (AF) is required to have a high current control capability of tracking a time-varying current reference. However, a steady-state current error always exists because the current reference varies in time. This paper proposes the application of adaptive digital signal processing (ADSP) to the current control of AF ADSP does not require any additional hardware. It can automatically minimize the steady-state error. Since the processing time available by a computer is limited, ADSP cannot eliminate higher order harmonics but can eliminate lower order harmonics such as 5/sup th/ to 17/sup th/. Experimental results demonstrate that ADSP is useful for improving filtering performance.
