ME 375 HOMEWORK #10 Fall 2009 Out: Nov. 4, 2009 Due: Nov. 11, 2009 PROBLEM 1 : (30%) A DC motor is driving a load as shown in the following figure. The motor has a Back-EMF constant b K , a torque constant T K , an armature inductance a L , and a resistance a R . The rotor has an inertia A J and a viscous friction B . The load has an inertia L J . The two inertias are connected by a shaft with a spring constant L K and an equivalent viscous damping L B . (a) Write the equations of motion for the motor and the load dynamics. (b) Draw the block diagram of the complete system. (c) Find the transfer function from the input voltage ) ( s E i to the angular position of the load ) ( s L Θ . PROBLEM 2 : (30%) Consider the automobile speed control system depicted in the following figure, where R is the desired speed, Y is the actual speed of the car, and W is the road grade (in percent) which represents the slope of the road. The constant K is the control input (the throttle angle), y H is the gain of the speedometer, and r H is input scaling factor.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
