Pressure to improve margins (supply driven)– Global competition
– World-wide saturation of markets
– Tightening legislation on ecosphere load and energy consumption
Tight control of product quality– Meet product specifications with high yields under smooth process operating conditions
Strong need to increase flexibility for enabling demand driven operation of production– Produce primarily those products that have market demand
– Take price advantage of demand niches in a saturated market

What are the benefits ?
Improved quality control– reduction in the standard deviation of parameters– stabilized process operations
Increased throughput– reduction in process shutdowns
– longer run times– More instantaneous throughput
Improved process efficiency– less energy usage
Flexible operation
Typical project payback: 3-12 months

Process Performance is not as good as you think
• PID controllers at lowest level
• 90 % of the controllers are PID’s
• More than 30 % of PID’s operates in manual
• More than 30 % of loops increase short term variability
• About 25 % of loops use default settings
• About 30 % of loops have equipment problems
• APC not useful when PID’s are badly tuned

Why RaPID?
• Simple, step like experiments
• Graphical inspection models (2 or 3 parameters) are too simple
• Controller design:
• Simple, rule based
• No flexibility (specifications)
• Stability & robustness
Limitations of classical tuners:

Why RaPID (ctd)
Solution with RaPID:• State of the art identification methods:
• Other inputs (shorter testing)
• Detailed information
• Efficient control design
• Optimisation based
• Engineering specifications
• Robust and stable
• Wide range of applications (slow and fast)
