Compensation for a measurable disturbance at the model's output 330 $a The loop-shaping approach consists of obtaining a specification in relation to the open loop of the control from specifications regarding various closed loop transfers, because it is easier to work on a single transfer (in addition to the open loop) than on a multitude of transfers (various loopings such as set point/error, disturbance/error, disturbance/control, etc.). The simplicity and flexibility of the approach make it very well adapted to the industrial context.This book presents the loop-shaping approach in its entirety, starting with the declension of high-level specifications 410 0$aISTE 606 $aRobust control 615 0$aRobust control. 676 $a629.8 700 $aFeyel$b Philippe$0893212 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a996208254803316 996 $aLoop-shaping robust control$92078166 997 $aUNISA
