Any engineering books on control theory and signal processing is systems theory using mathematics such as linear algebra, differential equations, etc. The reason why books like Meadow’s are so light on the math is that there is already a large body of works that use the mathematics. Books light on the math are meant to accessibly extend the philosophy to those who may feel they do not have the proper math background.

“Modern Control Theory” by Katsuhiko Ogata applies the theory to thermal systems, fluid systems, mechanical, electrical, etc.

“Discrete-Time Signal Processing” by Alan V. Oppenheim is a great book on its subject.

Both are related to analytical approaches to systems thinking.
