Simulink Control Design provides tools for computing simulation-based frequency responses without modifying your model. A graphical user interface GUI lets you design and analyze arbitrary control structures modeled in Simulink, such as cascaded, pre-filter, regulation, and multi-loop architectures. You can increase model accuracy by using test data to calibrate physical parameters, such as mass or resistance.

For example, you can use design optimization techniques to optimize controller gains to meet rise-time and overshoot constraints, or jointly optimize physical and algorithmic parameters to maximize overall system performance.

It lets you document software requirements and design specifications and produce reports from your models, all in a standard format. You can create detailed requirements traceability reports, author your own modeling style checks, and develop check configurations to share with engineering teams. Requirements documentation can be linked to models, test cases, and generated code. You can generate harness models for testing model components and code before the complete system becomes available.

It provides libraries of MuPAD functions in common mathematical areas, such as calculus and linear algebra, as well as specialized areas, such as number theory and combinatorics. You can extend the built-in functionality by writing custom symbolic functions and libraries in the MuPAD language. It includes predefined test elements that let you build and maintain standard test routines. You can map test variables into a result set for analysis.

This data-driven approach helps you describe systems that are not easily modeled from first principles or specifications, such as chemical processes and engine dynamics. It also helps you simplify detailed first-principle models, such as finite-element models of structures and flight dynamics models, by fitting simpler models to their simulated responses.

Layout of printed circuit boards to suppress undesirable electromagnetic radiation or interference. NIBIB-funded researchers are developing new computational tools that can incorporate newly available data sets into models designed to identify the best courses of action and the most effective interventions during pandemic spread of infectious disease and other public health emergencies.

Tracking viral evolution during spread of infectious disease. RNA viruses such as HIV, hepatitis B, and coronavirus continually mutate to develop drug resistance, escape immune response, and establish new infections. Samples of sequenced pathogens from thousands of infected individuals can be used to identify millions of evolving viral variants.

NIBIB-funded researchers are creating computational tools to incorporate this important data into infectious disease analysis by health care professionals. The new tools will be created in partnership with the CDC and made available online to researchers and health care workers.
