+**Model of the Stewart platform**:
+
+-   Struts are treated as flexible beams
+-   Payload and the base are treated as flexible plates
+-   The FRF synthesis method permits to derive FRFs of the Stewart platform
+
+The model is compared with a Finite Element model and is shown to give the same results.
+The proposed model is thus effective.

+
+**Control**:
+Combines:
+
+-   the FxLMS-based adaptive inverse control =&gt; suppress transmission of periodic vibrations
+-   direct feedback of integrated forces =&gt; dampen vibration of inherent modes and thus reduce random vibrations
+
+Force Feedback ([Figure 2](#figure--fig:wang16-force-feedback)).
+
+-   the force sensor is mounted **between the base and the strut**

+
+Sorts of HAC-LAC control:
+
+-   LAC: Decentralized integral force feedback
+-   HAC: Inertial control using accelerometers. Use of the Jacobian to decouple the motion and then Fx-LMS based adaptive control is used
+
+**Experimental validation**:
+
+-   All 6 transfer function from actuator force to force sensors are almost the same (gain offset)
+-   Effectiveness of control methods are shown
