Overview

The Deadband block generates zero output within a specified region, called its dead band. The lower and upper limits of the dead band are specified as the Start of dead zone and End of dead zone parameters. The block output depends on the input and dead zone:

If the input is within the dead zone (greater than the lower limit and less than the upper limit), the output is zero.

If the input is greater than or equal to the upper limit, the output is the input minus the upper limit.

If the input is less than or equal to the lower limit, the output is the input minus the lower limit.

The configuration values for this block are as follows:

Start of Dead Zone	If the input is less than or equal to this parameter, the output is the input minus this parameter
End of Dead Zone	If the input is greater than or equal to this parameter, the output is the input minus this parameter
Subsample Code	A code which determines the schedule for updating this block (every sample, even samples only, etc.) See Subsampling.
User Data 0	Application-specific data. See User Data Storage.
User Data 1	Application-specific data. See User Data Storage.

Deadband Simulink block

The Deadband block generates zero output within a specified region, called its dead band. The lower and upper limits of the dead band are specified as the Start of dead zone and End of dead zone parameters. The block output depends on the input and dead zone:The blocks update schedule is determined by the Subsample Code (See Subsampling). The following Parameter Dialog Box can be opened by double-clicking on the block in a Simulink Model (3 Input version shown):

Description

The Deadband block generates zero output within a specified region, called its dead band. The lower and upper limits of the dead band are specified as the Start of dead zone and End of dead zone parameters. The block output depends on the input and dead zone:

double	DEADBAND().LowerLimit	If the input is less than or equal to this parameter, the output is the input minus this parameter
double	DEADBAND().UpperLimit	If the input is greater than or equal to this parameter, the output is the input minus this parameter
