This case study guides you through the system identification process by using the sample data in the SI Data Samples VI.

The SI Data Samples VI includes data sets for a DC motor, a flexible robot arm, a ball and beam apparatus, an RC circuit, and so on. This case study uses the flexible arm data to demonstrate the system identification process and to compare different estimation methods.

The flexible arm is a nonlinear dynamic system. The System Identification VIs enable you to build models for linear systems. This case study guides you through obtaining a linear representation of a nonlinear system.
