Signal threshold

State value at which adaptive zero-crossing algorithm can stop bracketing

Model Configuration Pane: Solver

Description

The Signal threshold parameter specifies a tolerance on the zero-crossing signal value for the adaptive zero-crossing detection algorithm. The tolerance on the signal value allows the adaptive zero-crossing detection algorithm to stop bracketing when the algorithm finds the time at which the signal value is close enough to zero.

Dependencies

To enable this parameter:

Settings

auto (default) | scalar number

By default, the adaptive algorithm automatically determines the signal threshold. The signal threshold must be a scalar number greater than or equal to zero.

Using a signal threshold that is too small can slow down simulation.

Using a larger signal threshold can speed up simulation, especially in systems with strong chattering. Using a signal threshold that is too large can reduce the accuracy of simulation results.

Programmatic Use
