The U-Tune PID Tuning package was produced after years of problem solving and tuning for the North Sea oil and gas industry. Although the vast majority of processes can be characterised by simple delay-lag dynamics, many expensive tuning packages fail to cater for the excessive noise and disturbances typifying the process response. U-Tune succeeds by giving the process control engineer direct input into the process identification phase and by providing easy comparison of test results. The tuning algorithms have been thoroughly tested on compressor anti-surge and load sharing controllers, separator level controllers, produced water and water injection control systems, flaring, export control and much more.
