Create a tunable genss model, and evaluate the
current value of the Control Design Blocks of the model.
Typically, you use getBlockValue to retrieve the tuned values
of control design blocks after tuning the genss model using a
tuning command such as systune. For this example, create the
model and retrieve the initial block values.
G = zpk([],[-1,-1],1); C = tunablePID('C','PID'); a = realp('a',10); F = tf(a,[1 a]); T = feedback(G*C,1)*F; Cval = getBlockValue(T,'C')
Continuous-time I-only controller:

s
With Ki = 0.001Cval is a numeric pid controller object.
aval = getBlockValue(T,'a')aval =
10aval is a numeric scalar, because a is a
real scalar parameter.
Using the genss model of the previous
example, get the current values of all blocks in the model.
G = zpk([],[-1,-1],1); C = tunablePID('C','PID'); a = realp('a',10); F = tf(a,[1 a]); T = feedback(G*C,1)*F; S = getBlockValue(T)
S =
C: [1x1 pid]
a: 10
