Hi All, I'm trying to simulate a motor using Field-weakening control, however when i go to generate a look-up table, it says the matrix dimensions do not match. What dimensions are required to make this work?

Hi Daniel,
When you select "Automatically generated lookup-table" feature, the three fields -- "wMechanical (rpm)", "TqRef (N*m)", "Vdc (V)" should all be monotonically increasing vectors, not matrices. The size of the vectors does not matter, but keep in mind that for certian DC-link voltage levels, some torque levels at high speeds may not be achievable. When this happens, you'll encounter an error message saying that "No feasible current referencs found".
