Returning workspace outputs is supported with only single return argument

Dear,
I am trying to run a simulink model in m-code while optimizing ADRC parameters with PSO, but I get an error:
‘Returning workspace outputs is supported with only single return argument’.
The first figure is 'PSO_ADRC' code and the second figure is the simulink model 'ADRC_test'.
Hope someone can help me, thanks.

Hi Joe,
The problem lies with the way you are using sim() function in your code. sim() function can only return a single argument.
The single output from the sim function will contain the properties that you are trying to return. So you can first get the sim output in a single variable and then access and return those propertiy values.
