FIR Model Powered Alarm Advisor!
Cutler Technology Corporation’s new Alarm Adviser (AA) software will revolutionize Alarm Management. An open loop (all valve) Finite Impulse Response (FIR) model of the process will be used to predict the path the process will follow in reaching steady state. The prediction is based on all the changes that have occurred up until the present time in the independent variables for a time equal to steady state in the past and upon the current state of the process variables. A long the path, the limits will be checked against the predicted values of the dependent variables and an alarm indicated at the time of the occurrence in the future. The speed of the FIR model makes it possible to predict in a few minutes the path the process will follow in reaching steady state. For a typical process, the FIR model runs 100 to 150 times real time. A first principle dynamic model of the same process will run 1 to 5 times real time with the same fidelity. Read More
