This project was completed as part of the University of Maryland Aerospace Engineering Department's Applied Nonlinear Control course (ENAE 743). The end result has been placed here; the full repository history is in a private coursework repository.\n\n## Background\nNASA's GTM is a high-fidelity radio controlled model aircraft, which is used to research off-nominal flight control conditions. Chakraborty et al summarized the longitudinal state dynamics of NASA's GTM, approximated the dynamics as low-order polynomials, and then utilized existing sum-of-squares optimization software (such as [SOSTOOLS](https://www.cds.caltech.edu/sostools/)) to efficiently approximate the maximum elliptical subset of a trim condition's region of attraction.\n\nAs part of a Spring 2020 ENAE 743 final project, Chakraborty et al's results were summarized. First, the results were informally summarized and partially implemented with Python code in a [Jupyter Notebook](/Code/Carpinelli%20-%20ROA%20Estimation.pdf). Then, the results (replicated and not) were formally summarized in a [report](/Report/Carpinelli_ROA_Estimation.pdf).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcadojo%2Freplicated-roa-analysis","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcadojo%2Freplicated-roa-analysis","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcadojo%2Freplicated-roa-analysis/lists"}
