Prewarp frequency for the Tustin method, specified as a positive scalar.IF,DF — Integrator and filter methods
'ForwardEuler' | 'BackwardEuler' | 'Trapezoidal'Integrator and filter methods for rate conversion of PID Controller block, each specified
as one of the following:- 'ForwardEuler' — Integrator or derivative-filter state discretized as Ts/(z-1)
- 'BackwardEuler' — Ts*z/(z-1)
- 'Trapezoidal' — (Ts/2)*(z+1)/(z-1)
For continuous-time PID blocks, the default methods are 'Trapezoidal' for both
integrator and derivative filter. This method is the same as the Tustin method.For discrete-time PID blocks, IF and DF are determined by the Integrator method and
Filter method settings in the Simulink block and cannot be changed with
setBlockRateConversion.See the Discrete PID Controller and pid reference pages for more details about
integrator and filter methods.Definitions
Tuned Block
Tuned blocks, used by the slTuner interface, identify blocks in a Simulink model whose
parameters are to be tuned to satisfy tuning goals. You can tune most Simulink blocks
that represent linear elements such as gains, transfer functions, or state-space models.
(For the complete list of blocks that support tuning, see “How Tuned Simulink Blocks Are
Parameterized” on page 10-36). You can also tune more complex blocks such as
SubSystem or S-Function blocks by specifying an equivalent tunable linear model
(Control System Toolbox).Use tuning commands such as systune to tune the parameters of tuned blocks.You must specify tuned blocks (for example, C1 and C2) when you create an slTuner
interface.st = slTuner('scdcascade',{'C1','C2'})15 Alphabetical List
