... be used to design an effective input-shaping controller. In this section, we examine a subset of crane manipulation tasks where the crane is used to move payloads that remain near the ground. That is, the sum of the two cable lengths stays constant. Figure 4 shows the two oscillation frequencies...

... of the shaped control input is 4.29 × 10 − 4 s , and the length of the unshaped XPTOS input is 4.37 × 10 − 4 s (after which the unshaped XPTOS input has amplitude less than 10 − 5 A ) . The STOS control law drives the read/write arm to the desired track...

...S. E. Winters; J. H. Chung; S. A. Velinsky A multi-input multi-output surface shape control system model is developed to study wavefront aberration correction. The plant model represents a deformable mirror and utilizes a finite element model that is validated using an actual prototype deformable...
