PARR, PARI, PARB – Blocks with input-defined parameter
Block SymbolsLicensing group: STANDARD
Function Description
The PARR, PARI and PARB blocks allow, additionally to the standard way of parameters setting,
changing one of their parameters by the input signal. The input-parameter pairs are p and par
for the PARR block, ip and ipar for the PARI block and finally P and PAR for the PARB
block.
The Boolean input LOC (LOCal) determines whether the value of the par (or ipar, PAR) parameter is read from the input p (or ip, P) or is input-independent (). In the local mode the parameter par (or ipar, PAR) contains the last value of input p (or ip, P) entering the block right before LOC was set to on.
The output value is equivalent the value of the parameter , (or , ). The output of the PARR and PARI blocks can be additionally constrained by the saturation limits . The saturation is active only when .
