Position and velocity vectors are calculated by integrating the perturbed equation of motion (Cowell's equation). To update the state vectors, equation (9) is integrated numerically by using 4th order Runge-Kutta's as [11]: h Xo + (k₁ + 2 k₂ + 2k + k₁₂ ) step 6 (17) where vxo is the initial velocity at epoch, vx₁ is the predicated velocity, k₁ = axo, k₂ hstep = axo -k₁, k₁ = ax。+ k₂, ka xo+ hstep h3,, axo is the acceleration at epoch, 2 h. step 2 t step hstep is the step for the method, tstep m = Τ m is the sub steps number during one nnn revolution the used values 10,20,30,40, and 50, Tp is the satellite's orbital period, the used value 5317.5 second, and nnn is the step number during 400 revolutions, the used value is 800,1000,1200,1400, 1600, and 1800. X₁ = X + Вер 6 - hep (kk, +2 kk₂+ 2 kk, + kk₁) (18) where X is the initial position at epoch, X₁ is the predicated position, kk₁ = vx, kk₂ = vx+ hap kk,, kk, = vxo+ h 2 step 2 -kk₂, kk₁ = vxo+hstep kk3. In addition, Equations (17) and (18) can be used to calculate the other velocities and positions components by the same way.

Can you solve it analytically using laplace transforms and with Matlab code as well please. Thank You

Here we have a very simple one dimensional model of a stroke rehabili- tation patient supported by a robot. Often, when you have a controlled electromechanical system like a robot and a human working together, you want to separate them by a compliant mechanism (spring with stiffness k) so that the robot has some "give". Otherwise, if there are errors in the control of the robot it can be very uncomfortable for a patient. The spring has zero force when x, = xp = 0. The patient provides viscous damping with damping Xp coefficient c. Fp + C Patient mp k Xp Robot Arm Xr Figure 2: Schematic diagram of a very simplified model of a patient pushing against a robot. The robot supports the patient via a spring for safety. In this case we want to eventually determine the force that the patient is exerting on the robot as a function of time, so we'll do some steps towards that goal. Your tasks: A Draw the free body diagram for the patient mass (mass mp). B Write the equations of motion for the…

A velocity of a vehicle is required to be controlled and maintained constant even if there are disturbances because of wind, or road surface variations. The forces that are applied on the vehicle are the engine force (u), damping/resistive force (b*v) that opposing the motion, and inertial force (m*a). A simplified model is shown in the free body diagram below. From the free body diagram, the ordinary differential equation of the vehicle is: m * dv(t)/ dt + bv(t) = u (t) Where: v (m/s) is the velocity of the vehicle, b [Ns/m] is the damping coefficient, m [kg] is the vehicle mass, u [N] is the engine force. Question: Assume that the vehicle initially starts from zero velocity and zero acceleration. Then, (Note that the velocity (v) is the output and the force (w) is the input to the system): 1. What is the order of this system?
