certified service providerWebcast - Just say NO to Process Disturbances and Interactions
Do external disturbances drive your process away from target? Do you constantly have to deal with PID controllers that interact and fight one another, causing process oscillations?
Join Top Control and Matrikon experts as they show you how to easily measure the effects of disturbances and implement an effective feed-forward control strategy and how to identify and cancel interactions between PID loops, using Matrikon TaiJi 3.0.
PID loop interactions and process disturbances are a leading source of process variability and instability. The advanced techniques to deal with these (decoupling and feedforward control) have existed for decades, yet are seldom used or used incorrectly. This is because these techniques rely on 'textbook' methods to obtain the needed process models.
This tutorial webcast will show you how to employ new tools to easily obtain the effects of interaction and disturbances on your process (the models) and how to use these to break or eliminate loop interactions and the effects of disturbances. A highly interactive process with a common disturbance will be used to illustrate the solution with before and after results shown.
This webcast which will explain theory, practice and results, will include:
1. Example Process and Control Objective
a. Tuning objectives and procedure
2. 2. Decoupling Control
a. Measuring interaction between loops
b. De-tuning interacting loops (a quick fix)
c. Implementing decoupling to cancel loop interaction
3. 3. Feedforward Control
a. Measuring the effect of the disturbance
b. Implementing feedforward to cancel the disturbance
4. 4. Conclusions
