I have checked several other questions addressing similar issues as this one, but I am still not able to tweak my document the way I want.
I have this 2-line chapter title:
which looks awful in the TOC, spanning 3 lines:
I tried using \\ whichs partially does the trick in the TOC (I still need to find out how to place the first word in line 2 right under the first word from line 1), but adds an aditional line in the chapter title, which I do not want.
I am aware of the optional argument for \chapter[text in TOC]{Chapter title}, but I do not want to use 2 names for the same chapter.
I tried \chapter[Control Strategies for Wave Energy Converters: \\ State-of-the-Art]{Control Strategies for Wave Energy Converters: State-of-the-Art} which does the linebreak in the TOC where I want and fixes having the aditional line in the chapter title (I still need to find out how to place the first word in line 2 right under the first word from line 1). With the downside I get a warning "Package hyperref Warning: Token not allowed in a PDF string (Unicode): removing `\' on input line 180"
I tried also \texorpdfstring{}{} given by Gonzalo:
\chapter{ \texorpdfstring{Control Strategies for Wave Energy Converters:\\ State-of-the-Art}{Control Strategies for Wave Energy Converters: State-of-the-Art} }
but I get the same result as just using \\.
Any guidance?
Cheer!

Edited version:
I tried @Jasper proposal, but still with no avail:
using the "normal" \chapter{Control Strategies for Wave Energy Converters: State-of-the-Art} and \chapter{Optimal Control for Wave Energy Converters: Contributions}
chapterto 1.5 cm generally (\titlecontents{chapter}[1.5cm]...) and shift thetikzpicture1.5 cm to the left. This way, multiple lines will align properly and there is no need for manual line breaks any more. – Jasper Habicht Jul 30 '22 at 09:56
