The Limiter block passes its input signal as output signal as long as the input is within the upper and lower limits specified by the two additional inputs limit1 and limit2. If this is not the case, the corresponding limit is passed as output.
homotopyType in the Advanced tab specifies the
simplified behaviour if homotopy-based initialization is used:
NoHomotopy: the actual expression with limits is used
Linear: a linear behaviour y = u is assumed (default option)
Fixed: it is assumed that the output is fixed at the value
If it is known a priori in which region the input signal will be located, this option can help a lot by removing one strong nonlinearity from the initialization problem.
Description: = true, if strict limits with noEvent(..)
Description: Simplified model for homotopy-based initialization
Description: Fixed value of output in simplified model
Description: Has no longer an effect and is only kept for backwards compatibility (the implementation uses now the homotopy operator)
Description: Connector of Real input signal
Description: Connector of Real output signal
Description: Connector of Real input signal used as maximum of input u
Description: Connector of Real input signal used as minimum of input u
