The trade-off among different control loop performances

The trade-off among different control loop performances

In this latest blog, Max Veronesi discusses PID controllers and the trade-off between different control loop performances. Evaluating the differing variables affecting performance, Max provides a full overview covering tracking and regulation, as well as performance and robustness; and offers solutions to overcome the challenges.

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.

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.
