The Role of Feedforward in Process Control

The Role of Feedforward in Process Control

The design of the feedforward controller takes time and requires knowledge of the process and disturbance dynamics. Therefore, the decision of whether to implement or not to implement feedforward is a tradeoff. For this reason, it is interesting to have a quantitative index measuring the performance improvement that can be obtained by adding a feedforward compensator.

Beyond OTS

Beyond OTS

A high fidelity dynamic simulator is typically used for operator training. The primary goal of which is cost mitigation by familiarizing future operators with the control scheme utilized on site and the consequences of incorrect operation so as to minimize mistakes. When properly built, these simulators can, as outlined in this article, provide benefits well beyond those of OTS.

Basic Control Loops Performance Monitoring

Basic Control Loops Performance Monitoring

In many practical cases, PID controllers are poorly tuned because of the lack of time or operator skill, or because operating conditions change. Obviously, it is important to have relevant techniques able to automatically assess the performance of a PID controller and to retune the controller to optimize the performance. Learn more about a basic methodology that can be applied to various systems.

Optimal Lifecycle Management and GEMBA Capability

Optimal Lifecycle Management and GEMBA Capability

In Japanese, a special word known as “GEMBA-RYOKU” (GEMBA capability) is frequently used when discussing human resource issues in the Japanese manufacturing industry. While the word itself means “on-site capability”, this implies not only the worker’s skill, but also empowerment in the workplace ultimately contributing to improvements on the manufacturing level.
