Tunable Low-Pass Filter
In this example, you will create a low-pass filter with one tunable parameter a:
Since the numerator and denominator coefficients of a
tunableTF block are independent, you cannot use
tunableTF to represent
F. Instead, construct
F using the tunable real parameter object
Create a real tunable parameter with an initial value of
a = realp('a',10)
a = Name: 'a' Value: 10 Minimum: -Inf Maximum: Inf Free: 1 Real scalar parameter.
tf to create the tunable low-pass filter
numerator = a; denominator = [1,a]; F = tf(numerator,denominator)
F = Generalized continuous-time state-space model with 1 outputs, 1 inputs, 1 states, and the following blocks: a: Scalar parameter, 2 occurrences. Type "ss(F)" to see the current value, "get(F)" to see all properties, and "F.Blocks" to interact with the blocks.
F is a
genss object which has the tunable parameter
a in its
Blocks property. You can connect
F with other tunable or numeric models to create more complex control system models. For an example, see Control System with Tunable Components.
