Perturbed Iterative Feedback Tuning
Optimal performance of process control requires a controller synthesis based on a performance criterion. In order to minimize the criterion, a model for the process is normally required. Iterative Feedback Tuning (IFT) is a data driven methodology to tune controller parameters given a performance criterion, with penalty on the controlled variable deviations from a desired trajectory and with pe...
متن کاملITERATIVE FEEDBACK TUNING WITH GUARANTEEDSTABILITYFranky
This paper presents an identiication-based mechanism for introducing guaranteed stability when using a data-driven model-free iterative control design method known as Iterative Feedback Tuning. Also, the use of unbiased estimates of the Hessian is shown to signiicantly improve the user control over the tuning procedure.
متن کاملITERATIVE FEEDBACK TUNING FOR MIMOSYSTEMSFranky
In this contribution, we extend the Iterative Feedback Tuning (IFT) control method of 3, 4] to a multivariable setting. We report on an experimental study with this method when applied to a Single-Input-Multiple-Output torsional laboratory setup.
متن کاملIterative Feedback Tuning in Fuzzy Control Systems. Theory and Applications
The paper deals with both theoretical and application aspects concerning Iterative Feedback Tuning (IFT) algorithms in the design of a class of fuzzy control systems employing Mamdani-type PI-fuzzy controllers. The presentation is focused on twodegree-of-freedom fuzzy control system structures resulting in one design method. The stability analysis approach based on Popov’s hyperstability theory...
متن کاملImproving Convergence of Iterative Feedback Tuning
Iterative Feedback Tuning constitutes an attractive control loop tuning method for processes in the absence of an accurate process model. It is a purely data driven approach aiming at optimizing the closed loop performance. The standard formulation ensures an unbiased estimate of the loop performance cost function gradient with respect to the control parameters. This gradient is important in a ...
