# Essays on linear algebra

The key concepts in section 1. A vector is defined as a matrix with one column. A vector with n entries defines a vector in Rn. If you plot two vectors in R2, you can find the sum of the vectors graphically using Parallelogram Rule. Construct an unknown input observer for this system. This will create a variable y in your workspace, with 2 rows and columns. The first column contains y, the second contains y and so forth. Use this to drive your unknown input observer and use the unknown input estimation scheme discussed in class to determine whether a fault has occurred note that it will take a few time-steps for the observer to synchronize with the system, so the estimated inputs at the beginning should be disregarded.

We will be interested in diagnosing sensor faults in this system. Using the method described in class Section 4. In the file that you loaded, there is a variable labeled y, which is the output of the system over time-steps. It has three rows and columns; the first column contains y, the second contains y and so forth.

Use the provided inputs and outputs to drive your state estimator and use appropriate residuals to determine whether a sensor fault has occurred.

Note that it will take a few time-steps for the observer to synchronize with the system, so you might notice that the residuals are very large for the first 10 or 20 time-steps — you can disregard this portion of the curves.Our completely free ACCUPLACER Elementary Algebra practice tests are the perfect way to brush up your skills.
