PIDs are basic building blocks of plant DCS, their performance affects the plant productivity. Loop utilization in AUTO mode, controller accuracy, loop efficiency, process oscillations, parameter tuning are major challenges. Regular PID performance monitoring/diagnosis can help overcome the issues. Automated tool uses trends to show PID health index, establishes possible reasons for under-performance and gives suggestions for correcting the loop. Contributes to higher asset utilization and increased controller efficiency OPTIMakx-PID
..scientific, systematic & fully automated tool for PID optimisation
technical features
* Offline Data Read : Automatically reads OP/PV/SP/MODE trends for pre-defined set of PID loops from plant DCS (Historian) for required date/time period – on demand or as scheduled task.
* Data Health Index : detects and highlights bad, missing, outlier data. Generates single Data Health Index to show confidence for further usage.
* PID Performance Assessment : advanced statistics on process variables, several KPIs including utilization factor, control action accuracy, valve travel index, oscillation issues -etc) – graphical summary of overall PID health Index for groups of PIDs relevant to equipment /section /department /plant performance.
* PID Performance Diagnosis : Advanced analytics like classification of loops based on performance Index, diagnosis for under-performance, trend assessment, investigation for oscillations, control element abnormalities, design and tuning issues and more…) – based on scientifically proven algorithms.
* PID Performance Optimization : assessment for deviations from optimum limits, investigation on PID constants, smart PID tuning assist, offline PID simulation, detection of best performance patterns (shifts, operator, unit, month, season wise assessment of performance), alarms for preventive maintenance of controller components.
* Powerful Visualization : Innovative and User friendly graphical display of results which can be summarized and customized based on relevance at different levels (Chief/Manager/HoD/Engineer/Supervisor..) and different groups (plant, unit, section, equipment…).
tool features
