Question 1 The engine, body and tires of a racing vehicle affect the acceleration and speed attainable. The speed control of the car is represented by the model shown in figure 1. Calculate the steady-state error of the car to a step command in speed. Calculate overshoot of the speed to a step command. Figure 1: Racing car speed control

Question 2 A unity negative feedback control system has the loop transfer function , Determine the percentage overshoot and settling time (2% settling criterion) due to a unit step input. For what range of K is the settling time less than 0.5 second?
