Bilinear discrete-time modeling for enhanced stability prediction and digital control design [of switching power converters]
2002 IEEE 33rd Annual IEEE Power Electronics Specialists Conference. Proceedings (Cat. No.02CH37289) - Tập 2 - Trang 803-808 vol.2
Tóm tắt
This paper presents a new bilinear discrete-time modeling method for switching power converter circuits. The method utilizes a new approximation of the matrix exponential involved in the exact discrete-time models. Compared to the conventional bilinear discrete-time models or to the continuous-time averaged models, the new bilinear models provide a means for more reliable and accurate stability and transient response prediction. They also lend themselves better to digital control design than the exact discrete-time models due to their simplicity. The modeling method is validated by several example converters, for which traditional averaged models and conventional bilinear discrete-time models fail to predict the stability characteristics correctly.
