Concept explainers
Outside the United States speed is measured in Kilometers per hour (km/h) rather than miles per hour (mph). Although the exact conversion from km/h to mph is 0.57, a conversion factor of 0.6 is generally used because it is easier to remember. For the reverse conversion a factor of 1.7 is normally used. Perform the following conversions using the approximate conversion factors.
- What is the speed in mph of an automobile on the German Autobahn traveling at 160km/h?
- What is the speed in km/h of a motorcycle traveling at 70 mph in the United States?

- CONTROL SYSTEMS The system shown below has been tested with three different reference inputs 6u(t), 6tu(t), and 6tu(t). By using steady-state error calculation, identify which could give zero (0) steady state error. The function u(t) is the unit step.
