Limiter Icon

`Limiter`

Within the specified upper and lower limits, input signal is passed as output signal. Outside these limits, corresponding limits are passed as output.

This component extends from SISO

Usage

Limiter(u_max, u_min=-u_max, assertion=assert(u_max, u_min, Base.isgreater))

Parameters:

Name	Description	Units	Default value
`u_max`	Maximum allowed input	–
`u_min`	Minimum allowed input	–	-u_max
`assertion`	Internal parameter to assert that `u_max` is greater than `u_min`	–	assert(umax, umin, Base.isgreater)

Connectors

u - This connector represents a real signal as an input to a component (RealInput)
y - This connector represents a real signal as an output from a component (RealOutput)

Behavior

\[ \begin{align} y\left( t \right) &= max\left( min\left( u\left( t \right), \mathtt{u\_max} \right), \mathtt{u\_min} \right) \end{align} \]
