Software environment for robust H/sub 2/ and H/sub /spl infin// controller tuning and real time control

This paper presents a novel and flexible software environment for data acquisition and system identification in real time, oriented to process control. Our application implements PID, H₂ and H_infin tuning methods for systems whose process reaction curve may be considered that belongs to some of the considered response patrons. A novel procedure for H₂ and H_infin controller tuning is employed, valid for SISO and MIMO systems, which is easy to carry out for a plant operator. Evaluation tests are applied, and numerical indicators are used in order to validate the identified mathematical model and the designed controller. A friendly user interface facilitates monitoring, analysis and validation tasks
