If you want to generate code for fixed-step double- and single-precision targets, considering setting the parameter to The algorithm was tested using data from a laboratory 0.5 hp three-phase induction motor. Advertisement 4. This example determines the parameters of a three-phase AC induction motor (ACIM) using the recommended Texas Instruments hardware. Rotor flux is maintained constant by the rotor flux control scheme with feedback and estimation of rotor angle are carried out by the direct vector control technique. During an emergency, you can manually turn the Run-Stop slider switch to the Stop position to stop the parameter estimation tests. Open a third-party tool to deploy the binary files (.hex/ .out). The assessment is based on the closeness of the resulting parameter values to reference values and on the inexistence of absurd results, such as negative electrical resistances. This consist of a MatLab Function intended to estimate the parameters of a electrical induction motor. The methodology consist in minimize objective function to . The tool updates the display box Id0 (available in the Estimated Motor Parameters section of the host model) with the computed value only if you set this field to 0.
