Abstract: 

     Preview  Control for Dual-Stage Actuators (DSA) consists in allowing movement of the slow  actuator while maintaining the system output at the reference point. This  strategy is possible only if the fast actuator is able to compensate the  movement of the slow one. The advantages of this control scheme are related to  an improvement on the settling time of the output, a consequence of the fact  that the slow actuator is allowed to move ahead of the reference transition  time. This talk will discuss fundamental limitations that constrain the  trajectories of the primary actuator to a feasible set, i.e., a set whose  trajectories the secondary actuator is able to effectively compensate. From this  initial discussion optimal trajectories will be devised via quadratic  programming. Experimental results show the effectiveness of the  proposed design.
