PID Loop Tuning: Advanced course
Get to grips with advanced strategies such as feed forward and cascade control!
Designed to help attendees to analyse the static and dynamic characteristics of a range of processes and optimise controller settings for performance and robustness, this course also covers some of the common problems (unrelated to controller tuning) that occur on control loops causing poor performance and instability. Attendees will be competent to use a range of software tools and techniques to optimally tune PID controllers for a wide range of applications.
Day 1 (am): Control performance measures. Process modelling, transfer functions. First & second order lags. Transport delay. Multiple lags. Process non-linearities, variable gain and hysteresis. Process characteristics simulation.
Day 1 (pm): Process modelling exercise. Control loop stability. Relative stability margins. Control loop tuning problems. Filtering & slugging of measured values. Common causes of poor control loop performance. Review of common loop tuning methods.
Day 2 (am): Introduction to software‐based tuning toDay ols. Connectivity requirements: Standard signals. Step test procedures for modelling self‐regulating and integrating processes.
Using an OPC browser to access process data. Using a PROFIBUS analyser to access process data. Step testing and process modelling exercise. Performance criteria selection. Filtering tools & statistical analysis.
Day 2 (pm): Using software-based tuning tools to tune & optimise control loop performance. The effects of process non-linearities. Advanced control strategies. Cascade and feed forward control. Tuning cascade loops. Tuning feed forward compensation.
Day 3 (am): Tutorial and question & answer session. Practical and theory test.
To build on existing basic PID control knowledge and to develop the skills required to optimise controller settings for performance and robustness.
