Question 14 5 pts The following feedback loop represents a proportional controller for the position control of an electric car. The target position is given by the reference input R(s) and the position of the electric car is given by X(s). The transfer function of the electric car, given by G, has a current input (s), and a position output, X(s). R(S) Кр l(s) > G X(s) T() Write a line of Matlab code that determines RO) feedback(KpG); s'step(Kp.G) O 10 feedback(Kp'G,1); s'feedback(Kp'G, 1); feedback(Kp'G,1);

Question 15 5 pts The following feedback loop represents a proportional controller for the position control of an electric car. The target position is given by the reference input R(s) and the position of the electric car is given by X(s). The transfer function of the electric car, given by G, has a current input. l(s), and a position output, X(s). R(s) l(s) Кр G → X(s) Your good friend has already written the Matlab code to assign the variable X the transfer function R(5) It's your task to write a line of Matlab code to plot the position of the car when the input is r() = 10u(t). O step(10-X)/5: O step(10*X); 10'step(x); step(10*X/s): step(X)/10;
