ExperTune's solution is a setpoint filter combined with optimal tuning for steady state operation. The result is smooth setpoint response in combination with best response to process upsets. The setpoint filter is active only during setpoint changes. This allows the user to select ExperTune's optimal tuning for process upsets. With these PID settings in place, the feedback control loop is tightened to its utmost, giving excellent steady state optimization.
The setpoint filter ensures the loop also reacts well to plant startups and switchovers. You can use ExperTune to view the effects of the setpoint filter off-line in simulation before applying it to the process. Adjust the filter amount and immediately see the effect on the closed loop response. Tailor the response to exactly what your plant needs.
ExperTune creates a report of the entire loop optimization, including all the analysis graphs, performance indices, loop diagnosis and the setpoint filter in a Microsoft Word document. The report documents your loop for future records.
ExperTune's full suite of optimization tools make it easy to increase the efficiency of your process. Use ExperTune software to analyze and tune PID loops in any industrial controller. ExperTune includes powerful simulation, modeling, robustness, linearization, valve wear analysis, pH linearizer, time series analysis, multivariable, statistical, frequency response and loop tuning tools.
