-> The HAC/LAC approach consist of combining the two approached in a dual-loop control as shown in Figure [1](#org5a821d8). The inner loop uses a set of collocated actuator/sensor pairs for decentralized active damping with guaranteed stability ; the outer loop consists of a non-collocated HAC based on a model of the actively damped structure. This approach has the following advantages:

This approach has the following advantages:
 >
 > -   The active damping extends outside the bandwidth of the HAC and reduces the settling time of the modes which are outsite the bandwidth
 > -   The active damping makes it easier to gain-stabilize the modes outside the bandwidth of the output loop (improved gain margin)
 > -   The larger damping of the modes within the controller bandwidth makes them more robust to the parmetric uncertainty (improved phase margin)
