Two or more PID loops interacting and “fighting” can be menacing and challenging problem.
Many control engineers have struggled unsuccessfully because of PID loop interactions.
PITOPS PID tuning optimization and closed-loop system identification software from PiControl Solutions provides a novel and amazing new method for optimally tuning any number (not just two) of interacting PID control loops.
PITOPS will help you to reduce oscillations, achieve tight and stable control and will help you maximize your profits by improving the performance of MPC (DMC, RMPCT) or DCS-resident traditional APC.
PITOPS has the unique function to configure simulation for a setpoint change and also automatically configure typical disturbances seen by the PID control loop due to neighboring PID loop interactions. PITOPS then optimizes the PID control loop tuning parameters taking into account both the setpoint changes and the interactive “oscillatory” disturbances. The result will dampen oscillations and reduce the bad effects of PID loop interactions. All these calculations and simulations are displayed and configured entirely in the time domain – so there is no need for a PhD or advanced math skills.
With PITOPS, you can address PID control loop interactions quickly and make improvements before the day is over!
