Motor Control Blockset Examples "Dot indexing is not supported for variables of this type"

3 views (last 30 days)
It's my first time using Simulink. The first thing I did when I opened the program is I opened an example under "Motor Control Blockset" on the Simulink start page. In the window that opened (a Simulink window), I clicked run, and received the message "Dot indexing is not supported for variables of this type." I tried several other examples under "Motor Control Blockset" and they all gave me the same error. There's no stack trace, so I really don't even know where to start debugging this. Is this a bug or am I doing something wrong?

Hello Nathan,
I understand that you are encountering an error while trying to execute the “Field-Oriented Control of PMSM Using Hall Sensorexample in Simulink.
Before simulating this example, please make sure that you have the following required MathWorks products installed by using the “ver” command in the command window:
  1. Motor Control Blockset
  2. Fixed-Point Designer
Also, please follow these steps to simulate the model correctly:
  1. Open the model included in this example by simply using this command:
open_system('mcb_pmsm_foc_hall_f28069m.slx');
  1. To simulate the model, click ‘Run’ on the ‘Simulation’ tab.
  2. To view and analyse the simulation results, click ‘Data Inspector’ on the Simulation tab.
For more information on this example, consider going through the documentation page of this example:
I hope this helps!
