我正在写论文，但在参考书目方面遇到了一些问题。我使用以下配置：
\usepackage[
backend=biber,
style=ieee,
sorting=none
]{biblatex}
\addbibresource{bibliography.bib}
平均引用如下：
@article{general_article,
author = {Egerstedt, Magnus and Martini, Simone and Cao, Ming and Camlibel, Kanat and Bicchi, Antonio},
title = {Interacting with Networks: How Does Structure Relate to Controllability in Single-Leader, Consensus Networks?},
journal = {IEEE Control Systems Magazine},
year = {2012},
volume={32},
number={4},
pages={66-73},
}
结果如下：
M. Egerstedt, S. Martini, M. Cao, K. Camlibel e A. Bicchi, ≪Inte-
racting with Networks: How Does Structure Relate to Controllabi-
lity in Single-Leader, Consensus Networks?≫ IEEE Control Systems
Magazine, vol. 32, n. 4, pp. 66–73, 2012
我的问题是，如何自定义引文的外观？我的导师说引文中通常不使用 <<>>，但我找不到如何自定义外观，也找不到避免使用它们的样式。
谢谢您的帮助！
