Simulink Control Design™ - MathWorks

Best overall soft constraint value, returned as a scalar. systune converts the soft goals to

a function of the free parameters of the control system. The command then tunes the

parameters to minimize that function subject to the hard constraints. (See “Algorithms”

on page 15-483.) info.fBest is the maximum soft constraint value at the final iteration.

This value is only meaningful when the hard constraints are satisfied.

gBest — Best overall hard constraint value

scalar

Best overall hard constraint value, returned as a scalar. systune converts the hard goals

to a function of the free parameters of the control system. The command then tunes the

parameters to drive those values below 1. (See “Algorithms” on page 15-483.)

info.gBest is the maximum hard constraint value at the final iteration. This value must

be less than 1 for the hard constraints to be satisfied.

fSoft — Individual soft constraint values

vector

Individual soft constraint values, returned as a vector. systune converts each soft

requirement to a normalized value that is a function of the free parameters of the control

system. The command then tunes the parameters to minimize that value subject to the

hard constraints. (See “Algorithms” on page 15-483.) info.fSoft contains the individual

values of the soft constraints at the end of each run. These values appear in fSoft in the

same order that the constraints are specified in SoftGoals.

gHard — Individual hard constraint values

vector

Individual hard constraint values, returned as a vector. systune converts each hard

requirement to a normalized value that is a function of the free parameters of the control

system. The command then tunes the parameters to minimize those values. A hard

requirement is satisfied if its value is less than 1. (See “Algorithms” on page 15-483.)

info.gHard contains the individual values of the hard constraints at the end of each run.

These values appear in gHard in the same order that the constraints are specified in

HardGoals.

MinDecay — Minimum decay rate of closed-loop poles

vector

Minimum decay rate of closed-loop poles, returned as a vector.
