Título do capítulo no centro da tese

Título do capítulo no centro da tese

Eu queria colocar o título do capítulo no centro, em vez de alinhado à esquerda. eu usei

\usepackage{sectsty}
\chapterfont{\centering} 

que colocou o título do capítulo no centro, mas começou quase no meio da página, o que parece ruim na minha tese. Quero o título centralizado e começando a uma distância razoável do cabeçalho da página, como o "Resumo" ou outras páginas da minha tese.

aqui está meu arquivo tex:
