Quality update to bring in Design ver. 1.12.0

General Guidelines: - The reviews shall be performed over the portions of the component that were modified as a result of the Change Request. (Note: If this peer review form was not completed for pervious versions of this component, the Change Owner should review the entire component and complete the checklist in its entirety prior and check the form into Syngery. This may be done prior to reviewing the modifications for this Change Result) - The Change Owner shall responsible for completing the entire checklist (Pre and Group review items) prior holding the initial group review. - New components should include FDD Owner and Intergator as apart of the Group Review Board (Source Code, Integration Manual, and Davinci Files) - Select "Yes" and add "N/A" to the comments for checklist items that are not applicable for this change - Enter any rework required into the comment field and select No. When the rework is complete, review again using this same review sheet and select Yes. Add date and additional comment stating that the rework is completed. - To review a component with multiple source code files create a Source code tab for each source file. - .h file should be reviewed with the source file as part of the source file.

Software Component Implementation

Sub-Module Functions

Initialization sub-module InertiaCmpVelInit1()

Design Rational:

Init function is not present in the model but in reference to the Init.txt text file Low pass filter and Notch filter are initialized.

For Low pass filter standard EA4 LPF implementation from NxtrFil.h is followed and for Notch filter initialization, EA3 implementation is followed.

UNIT TEST CONSIDERATION

1. Since the notch filter implementation used in this module is dynamic in nature, absolute ranges are difficult to determine without pre-defined knowledge on the combination of coefficient values (A1, A2, B0, B1, B2). Because of this, the systems group ran simulations on 10 different combinations of coefficients (2 with defined default calibrations, 8 considered extreme cases of notch filters) and logged the ranges of the filter state variables and outputs during a frequency sweep. The ranges given throughout this module were taken as the worst case results of all of the given test cases.

To provide useful cases for unit testing, the boundary checks tested during unit testing should be altered to test the state variable minimum and maximum for each of the 10 test cases with the given coefficients set to the values given in that test case. In the case where the default values of the coefficients are used in a vector, the unit tester should not test the corresponding state variables with values over the range defined for that set of coefficients. See attached simulation results.

2. GenFddIcCmd function is designed to work with argument values from the calling function as used with the other functions in the module, and outputs may be out of the expected range if tested with arbitrary combinations of input values. Unit testing of this function should use only passed argument value combinations coming from the calling function.
