Python 🐍 Curve Fit with Step Test Data

The Scipy curve_fit function determines two unknown coefficients (dead-time and time constant) to minimize the difference between predicted and measured response values. Pandas imports the data and the dataframe header is diplayed with x.head(). Conditional statements are used to create a step function and curve_fit from Scipy.optimize finds the optimal parameter values that minimize a sum of squared error. A Matplotlib plot shows the function with optimal parameter values. An R-squared value is 0.999, showing excellent agreement between the predictions and measurements.
