Signal threshold

Description

Specifies the deadband region used during the detection of zero crossings. Signals falling within this region are defined as having crossed through zero.

The signal threshold is a real number, greater than or equal to zero.

Category: Solver

Settings

Default: auto

By default, the zero-crossing signal threshold is determined automatically by the adaptive algorithm.
You can also specify a value for the signal threshold. The value must be a real number equal to or greater than zero.

Tips

Entering too small of a value for the Signal Threshold parameter will result in long simulation run times.
Entering a large Signal Threshold value may improve the simulation speed (especially in systems having extensive chattering). However, making the value too large may reduce the simulation accuracy.

Dependencies

To enable this parameter:

Set the solver Type to Variable-step.
Set Zero-crossing control to either Use local settings or Enable all.
Set Algorithm to Adaptive.
