data in the lookup table ITBL block

13 views (last 30 days)
Hi everyone,
I would like to see the information about the data inside the ITBL or TTBL block (both belong to the Switched Reluctance Motor configuration) to be able to plot the characteristics of the Current vs the rotor position for example and get the reluctance curve for different values of flux. The problem is that when I click on the block parameters(lookup2D) of this block and click to the edit button to see the data this motor uses to simulate. An error warns me out about something I don't understand. What's the problem? If you can help me I would be very grateful.
Some screenshots attached

@alvaroDear alvaro, please share the ITBL and TTBL tables if you got the solution. I am currently working on srm 6/4 and it would be very grateful for me if you share the solution

Hi Alvaro,
The values for ITBL and TTBL are generated from the Magnetization characteristic table which is specified in the "Model" tab of the Switched Reluctance Motor block parameters. By default, the values are loaded from a MAT file called "srm64_60kw.mat". The magnetisation characteristic table includes the machine's flux corresponding to different rotor angles (defined by the "RotorAngle" variable) and stator current (defined by the "StatorCurrent" variable).
I hope this helps.
Sebastian

Can you explain how we can add data to the lookup table from excel please

I have a lookup table data for my motor. The table has inputs breakpoint vectors as rotor position and current and the output (table data) is flux linkage values. But i want to change the axis of the graph. I want the current values for given input rotor position and flux linkages. How to do it? please help.
