ARLY – Advance relay

Block SymbolLicensing group: STANDARD
PIC

Function Description
The ARLY block is a modification of the RLY block, which allows lowering the amplitude of steady state oscillations in relay feedback control loops. The block transforms the input signal u to the output signal y according to the diagram below.
