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.

The "Magic Number" in Human Memory Capacity

The "Magic Number" in Human Memory Capacity

It is very critical that we try to understand operations by understanding our operators, from their point of view. Then, when implementing technologies, we focus on implementation in a manner that matches with the manner in which the operators think, and towards the goals that they need to achieve. Too often there is a focus on adding new and extra information/data.

Industrial Cyber Security – Securing Operational Technology 101

Industrial Cyber Security – Securing Operational Technology 101

In the modern connected enterprise where your industrial systems are networked to your business systems (which they almost certainly are) and your business systems are Internet facing (again very likely) then your business systems should be regarded as a potential source of threat to the integrity, safety and security of your control systems. That threat should be properly managed.
