Graph should look like this
Task 3. Suppose that the vehicle has a mass m= 1000 kg and a coefficient of friction b 150 N-s/m. Define the transfer function G in MATLAB using tf. The tf function has the syntax tf (num, denom) where num represents the coefficients of the numerator and denom represents those of the denominator in descending order. * Write your code to define G here Task 4. Plot the step response for the first 60 seconds using the step function. The step function has the syntax step(sys, Tfinal) where sys is a dynamic system (here, the transfer function 6) and Tfinal is the simulation stop time I Write your code here
v (m/s) 8 6 2 x 10-3 0 0 20 40 t (s) Step response 60
In this model, the variables and parameters are: . x, i, ï: the position (m), velocity (m/s), and acceleration (m/s2) of the vehicle in the direction of travel, respectively .: traction force generated by the engine (N) • m: vehicle mass (kg) . b: coefficient of friction (N-s/m) The differential equation model is constructed using Newton's second law mi-bx+u (1) The traction force is considered to be the input to the system and is therefore labeled . A cruise control system attempts to determine the value of a to achieve a desired response.
