Your answer is incorrect. Problem lies in going from step 2 to 3. (1-G5) term can be taken in denominator of G4 only if they are in feedback loop. In this case, they are not in loop and as a result, your answer is wrong. The correct answer would be: Y=X[(G5+(G1/(1-G1G3)(1-G5)))G2+G1G4/(1-G1*G3)] Thank you

I solved it. Theory is correct, the problem was $\dot{\mathbf{q}}_{r}$ in simulink, I was being redundant with the variables, so instead of using the derivatives that were already in simulation I was adding more derivative blocks and probably causing issues in simulation. Plus to make sure I had no errors in the regressor, I basically have rewritten it as: \...

I think this problem has the following structure: $y$ corresponds to the disturbance from the road $x_o$ corresponds to the travel of the unsprung mass $x_i$ corresponds to the travel of the sprung mass This is in accordance to this image. For this problem, I think masses should be assigned to displacement $x_o$ and $x_i$. Otherwise there is not much ...

First, find the energy balance - basically mass flow x thermal capacity x delta T is the same on both sides. Edit to add There's an error in your energy balance: on the left hand side it's simply $\Delta T$, not the derivative. Also make sure to use the correct values for $c$ as you have two different media. Then, find something like this for your valve: ...
