A quarter car model used for the analysis of suspension dynamics is shown in Figure Q2a. To avoid mode coupling, the hub mode (the motion dominated by 35 kg mass) has to occur at 14 Hz. For this limiting case calculate the value of tyre stiffness. ↑ 230 kg X2 3x10 N/m ↑ 35 kg X₁ m

Can you please code in MATLAB. Generate 10 unit vectors in the body frame and the corresponding vectors in the inertial frame of your choosing. Use four different noise levels on the unit directions: one arcsecond,10 arcseconds, 1 degree and 5 degrees. Assume first the measurement error is Gaussiandistributed, secondly, that it is Poisson distributed. Compare TRIAD, Davenport’s q-methodand QUEST, comment on the findings.

The following EOMS describe the behavior of an electric motor attached to a torsional spring and damper: [Li + Rz + vb = Vin(t) IÖ= k0b0 + T Importantly, the equations are coupled by the fact that 7 = k₁z and v₂ = k₂0. Here, L, R, kv, I, k, b, and kt are constants. z is the current in the motor, and is the angular displacement of the motor (clearly then, is the motor's angular velocity). Finally, the input to the system is vin (t). Your tasks: A Substituting in the coupling terms (7 = ktz and v k0) into the EOMs, write the state space form of the system x = Ax + Bu, assuming your states are x₁ = z, x₂ = 0, and x3 = 0. Clearly identify your matrices. B Assume that the desired outputs of the system (to be measured) are the current z, the angle and the input Vin all as separate elements in the vector y. Write the output equation y = Cx + Du. Hint: D will NOT be zero in this case. Clearly identify your matrices C Assume there is no stiffness to the spring (k = 0). Using w(t) to represent…
