Remove control dependency

[adeebshihadeh]

It's just used in one place in one test:

openpilot/selfdrive/controls/lib/tests/test_vehicle_model.py

Line 50 in a1dce6e

ss = StateSpace(A, B, np.eye(2), np.zeros((2, 2)))

The goal is to replace it with pure Python (and some numpy).

uv pip tree for control:

control v0.10.0

Hi @adeebshihadeh ,
I am very interested in working on this issue, and I have thoroughly reviewed the codebase. I am confident in my ability to resolve this issue. Here’s my approach:

1. State-Space Replacement: I will implement a custom StateSpace class using pure Python and NumPy to replace the dependency on the control library. This class will handle continuous and discrete-time systems, ensuring compatibility with the existing codebase.
2. Integration and Testing: I will integrate the new StateSpace class into test_vehicle_model.py, replacing the current usage of the control library. I will ensure that all existing tests pass and maintain the functionality of the original implementation.

Given my experience and this detailed plan, I am confident in my ability to address this issue effectively.

Could you please assign this issue to me?

Thank you!
