Automatic Control Engineering Problem Solver

I'm in need of a skilled engineer with expertise in Automatic Control Engineering. My questions primarily focus on:

- Stability analysis
- Control system design
- Transfer Functions: block diagrams and signal flow graphs

The questions are presented in essay format and problem-solving computations, so strong written communication skills will be essential.

Please note that the problems are to be solved on paper, so a meticulous and clear writing style is crucial.
