Measure position of resolver sensor

Since R2024a

  • Resolver block

SoC Blockset Support Package for Infineon AURIX Microcontrollers / AURIX TC4x


The Resolver block measures the position of a resolver sensor and also capable of generating the excitation carrier signal for the resolver sensor.

The Resolver block outputs the angle of the resolver sensor in either radians (default) or degrees. The block outputs a measurement based on the sensed sine and cosine voltages of the resolver sensor.

Enabling the timestamp option creates an additional output port that outputs the timestamp in seconds from the last conversion as a signed value.

The block outputs the position of the resolver sensor in radians (default) or degrees. The size of θₘ output depends on the Enable timestamp parameter.

Selecting the Enable timestamp parameter results in θₘ of size 2x1 and disabling Enable timestamp parameter results in θₘ of size 1x1.

The port outputs the timestamp indicating the time elapsed in seconds from the last conversion.


To enable this port, select the Enable timestamp parameter.

Select the position measurement unit for the resolver sensor.

Select to enable the timestamp.

When you select the Enable timestamp parameter, the block configures an additional output port timestamp.

Selecting of this parameter enables options in the Timestamp tab and Timestamp event (under Events tab) in the Resolver Peripheral Configuration window.

Specify in seconds how often the block must read the position of the resolver sensor.

When you specify this parameter as -1, Simulink® determines the best sample time for the block based on the block context within the model.
