Domains: Continuous, Discrete. Size: 1-D. Kind: Block Diagrams.

Description

This is a PID controller in series form with setpoint weighting. The output of this controller (in s-domain) is:

PID_s_sp_Equation

An anti-windup scheme has been added to this controller as well as an offset for manual output at start-up. An external tracking signal must be supplied to activate the anti-windup scheme.
