The Unit Delay With Preview Resettable block supports calculations that have feedback and depend on the current input.
The block can reset its state based on an external reset signal R. The block has two output ports. When the reset R is false, the upper port outputs the signal and the lower port outputs the signal delayed by one sample period.
When the reset R is true, the block resets the current state to the initial condition given by the Initial condition parameter. The block outputs that state delayed by one sample time through the lower output port, and outputs the state without a delay through the upper output port.
The input u can be any data type. The output is the same data type as the input u. The reset R can be any data type.
You specify the time between samples with the Sample time parameter. A setting of -1 means the Sample time is inherited.
The Unit Delay With Preview Resettable block accepts signals of any data type supported by Simulink software, including fixed-point and enumerated data types.
Specify the initial condition.
Specify the time interval between samples. To inherit the sample time, set this parameter to -1. See Specifying Sample Time in the online documentation for more information.
