Repeat using MATLAB. The program will do the following in one program: a. Display a root locus and pause. b. Display a close-up of the root locus where the axes go from 2 to 0.5 on the real axis and 2 to 2 on the imaginary axis. c. Overlay the 0.707 damping ratio line on the close-up root locus. d. Allow you to select interactively the point where the root locus crosses the 0.707 damping ratio line, and respond by displaying the gain at that point as well as all of the closed-loop poles at that gain. The program will then allow you to select interactively the imaginary-axis crossing and respond with a display of the gain at that point as well as all of the closed-loop poles at that gain. Finally, the program will repeat the evaluation for critically damped dominant closed-loop poles. e. Generate the step response for the critically damped case.
PURDUE UNIVERSITY JANUARY 19, 2017 DA TAMINING BACKGROUND & BASICS DATAQUALITY BACKGROUND & BASICS DATAQUALITY ▸ Examples of data quality problems: ▸ Noise Outliers ▸ ▸ Missing values ▸ Duplicate data BACKGROUND & BASICS NOISE ▸ Noise refers to measurement error in data values ▸ Could be random error or systematic (bias) error BACKGROUND & BASICS OUTLIERS ▸ Outliers are data objects with characteristics that are considerably different than most of the other data objects in the data set ▸ Could indicate “interesting” cases, or could indicate errors in the data BACKGROUND & BASICS MISSINGVALUES ▸ Reasons for missing values ▸ Information is not collected (e.g., people decline to give their age) Attributes may not be appl
