Pitops Uniqueness

  • Multivariable identification– can handle multiple input and multiple outputs.
  • Uses Closed-Loop Data (does not need Open-Loop Step Tests).
  • Works well even if noise and unmeasured disturbances are present.
  • Requires short data window for successful analysis.
  • Calculated PID tuning parameters match exactly with DCS/PLC.
  • Pitops identification and simulation looks like the real DCS/PLC trends.
  • Displays PID output trends explicitly to ensure safe control action.
  • Equipped with latest 3G (geometric/gradient/gravity) technology for rejecting noise and disturbances and calculating true transfer functions.
  • Super-fast execution and super compact code size.
  • Pitops technology is far superior to ARMAX identification, Step Response Coefficient models, Ziegler Nichols, Lambda tuning, frequency domain, Z-discrete domain etc.
  • Pitops is far superior and easier than any other product or technology.
  • Pitops 4GRG algorithm and technology is a revolutionary, novel and a 21st century genuine breakthrough.
  • Does not need advanced education degrees, does not need complex math and theory.
