I am not sure of my answer, that's why I posted it. You are welcome to ignore it. And by solved, I solved it (hint).

I posted the answer to the questions: 1) what is the state space formulation 2) is the system controllable all in the attached PDF. Regards

I wrote the potential solution to the problem, showing that with the given problem statement, LQR, PID, or any other control approach will not allow the system to be controlled. Please check out the attached PDF, and please provide feedback if you can.

$$\underline{x} =\begin{bmatrix} \dot{x_{1}} \\ \dot{x_{2}} \end{bmatrix} = \begin{bmatrix} 0 & 0 \\ 1 & 0 \end{bmatrix} $$

Thank you. I'm in the process of converting my post according to your recommendation hinting to use Latex.

(u1*T1) + (u2*T2) = m (x dot dot), [1.1] where (x dot dot) is the 2nd derivative of the point-mass position with respect to time, u1 is the control input for the 1st thruster, u2 is the control input for the second thruster. Rearranging equation 1.1 yields (x dot dot) = (T1/m)*u1+...

Hi everybody. I like to model dynamical systems, but over the last few years, I've been busy implementing simulations, without actually deriving their equations of motions. I'm thus here to check with members whether some systems for which I wrote the equations of motions are actually corrects.
