The toolbox now supports estimation and validation using frequency domain data. We start by configuring the sound card to acquire 1. Figure 8: Results for 2-14 scaling. h (see the code sample in Using Real-Time Workshop Embedded Coder for Simulink Data Objects). To work around this problem, you can use a Data Type Conversion block, which does have a preprogrammed exact linearization, to convert your signals to doubles before linearizing the model. Figure 1: Top level of Simulink model. Three interconnected blocks correspond to the three compartments of the system.
