Delay input physical signal by specified time
The PS Constant Delay block generates the output
y, by delaying the input physical
y = u ( t – τ )
where τ is the delay time.
The delay time is constant throughout the simulation. You specify the value of the delay time as the Delay time parameter.
For the initial time interval, when t <= StartTime + τ, the block outputs the Input history parameter value.
When simulating a model that contains blocks with delays, memory allocation for storing the data history is controlled by the Delay memory budget [kB] parameter in the Solver Configuration block. If this budget is exceeded, simulation errors out. You can adjust this parameter value based on your available memory resources.
For recommendation on how to linearize a model that contains blocks with delays, see Linearizing with Simulink Linearization Blocks.
The output signal value during the initial time interval, until
the specified delay time elapses after the start of simulation. The
default value is
The delay time for the signal. The parameter value must be positive.
The default value is
The block has one physical signal input port and one physical signal output port.
