what type of error is this? is this the logical error, simulation error, code error?

[Fangjun Jiang]

syntax errors

[Infinite_king]

This is a Code error, probably because of the use of uninitialized variables.

[Engr.]

how to resolve that error as im trying to Implement voltage based cell balancing using a buck-boost converter and the control logic is implemented using Stateflow in SIMULINK.

Answer 1

Hi Engr,

This means that Stateflow cannot automatically resolve what type of data is present in your chart. If you open the symbols pane from the Modeling tab you should see warnings for the unresolved variables. From there you should be able to specify whether it is input data, output data, etc.

Also, if you are working with battery management systems I would highly recommend taking a look at Simscape Battery - it has a number of prebuilt BMS algorithms that might be of use.

TargetDeltaV is not defined. Meanwhile, you assign to DeltaV but do not use DeltaV in the code.
