Discontinuities

R2026b

Blocks for modeling nonlinear discontinuities, such as Saturation, Rate Limiter, and Relay

Use blocks from the Discontinuities library to model nonlinear elements where output changes abruptly in response to input. You can represent saturation limits, dead zones, backlash, static and dynamic friction, and hit crossings in your system.

To add blocks from this library to your model, see Add Blocks to Models.

Blocks

	Backlash	Model behavior of system with play
	Coulomb and Viscous Friction	Model discontinuity at zero, with linear gain elsewhere
	Dead Zone	Provide region of zero output
	Dead Zone Dynamic	Provide dynamic region of zero output
	Hit Crossing	Detect crossing point
	PWM	Generate ideal pulse width modulated signal corresponding to input duty cycle
	Quantizer	Discretize input at given interval
	Rate Limiter	Limit rate of change of signal
	Rate Limiter Dynamic	Limit rate of change of signal
	Relay	Switch output between two constants
	Saturation	Limit input signal to upper and lower saturation values
	Saturation Dynamic	Limit input signal to dynamic upper and lower saturation values
	Variable Pulse Generator	Generate ideal, time varying pulse signal
	Wrap To Zero	Set output to zero if input is above threshold
