Diagnostics and Prognostics

Apply model identification, response prediction, and online estimation methods for condition monitoring, fault detection, and remaining useful life (RUL) prediction

You can use measured data from your system to identify linear and nonlinear black-box and grey-box models. You can use these models to track parameter changes, forecast system response, and compute the associated response uncertainty. You can then employ these predictions for condition monitoring and fault detection.

You can use online parameter estimation techniques to monitor the condition of your system in real time, diagnose faults, and predict remaining useful life. You can also deploy the online estimation code to an embedded target using MATLAB® Compiler™ or MATLAB Coder™.
