instead.

Tips
For MIMO feedback loops, the
LoopShape
,MinLoopGain
,MaxLoopGain
,Margins
,Sensitivity
, andRejection
goals are sensitive to the relative scaling of each SISO loop.systune
tries to balance the overall loop-transfer matrix while enforcing such goals. The optimal loop scaling is stored in the tuned closed-loop modelCL
returned bysystune
. For consistency,evalSpec(R,CL)
applies this same scaling when evaluating the tuning goals. To omit this scaling, useevalSpec(R,CL,[])
.Modifying
CL
might compromise the validity of the stored scaling. Therefore, if you make significant modifications toCL
, retuning is recommended to update the scaling data.
