Q1)
Prefilters are used to:
(Select all that apply)
Increase the bandwidth of the loop
Improve reference input (set-point) tracking
Make the disturbance-to-output transfer function close to 0 atthe frequencies of interest
Improve disturbance attenuation
Adjust the loop transfer function at the frequencies ofinterest
Make the reference-to-output transfer function close to 1 at thefrequencies of interest
Reduce the bandwidth of the loop
Q2)
Select all that are true
An observer allows us to estimate the states of a system withoutsensor measurements.
Meticulous modeling will allow us to obtain system models thatdo not have uncertainties
Feedback controllers stabilize or improve stability margin
Feedforward controller does not change sensitivity and loopstability
Feedforward controllers provide faster corrections thanfeedback
Feedback controllers slow down the system response
Q3)
Select all that are true
System Identification is the process of identifying systems byusing equations from other disciplines
System Identification requires some system knowledge to select areasonable model structure
Estimating the magnitude of model uncertainty is not necessarywhen the model is obtained by first principles
Sufficient excitation is a necessary condition for good systemidentification experiments.
Estimating the magnitude of model uncertainty is not necessarywhen the model is obtained by system identification
