1.) Why is lead compensation important in a bridge circuit?
2.) What are the advantages to using a bridge with all elements active? (Notes and Handouts)
3.) Given a two element active bridge with one element at 200.8 ohms and the other elements all at 200 ohms and a reference voltage of 10 VDC what is the output across the bridge – show all work. (Notes, Handouts)
4.) What is Slew Rate?
5.) If we had a large CNC unit with a 0.05 in/sec velocity would this be acceptable – how do you determine if it is acceptable.
6.) What are the symptoms of a failing internal bearing in terms of vibration measurement? How would you measure this to make this determination – include information on a complete vibratory measurement system with the ability to record and reproduce data.
7.) Draw a temperature sensing circuit using the LM35 to convert 25° C into 2.5VDC.
8.) How would you calibrate a vacuum pressure sensor – draw out a picture and use real devices (Name and model number) in your answer.
9.) Name at least 4 ways to measure flow?
10.) How many pulses does it take to rotate the Stepper Motors you used in class 33.5 degrees? Show a diagram of the signals required to step the motor.
11.) Explain the difference between a time domain signal and a frequency domain signal.
12.) When would you select the frequency domain signal over the time domain signal.
13.) Why do we use a PID controller?
14.) In a control system the safety loop should be (part of) or (external to) the main control loop?
15.) Make a simple drawing which shows stable, unstable and neutral conditions.
16.) Discuss the concept of an alias signal and how do we prevent this from occurring.
17.) Given (s-3)/(s+5) as the transfer function of a system is it stable, plot the poles and zeros.
18.) What were your constants for the ping pong ball lab- what method did you use to achieve your results.
19.) Describe how the stepper motor controller you built works.
