The performance improvements provided by the input-shaping controller, as well as operator learning effects, are reported. bridges (structures) cranes damping human factors input-output stability pendulums shape control...

... maneuver. It is shown that the results of the linear programming problem are nearly identical to that of the nonlinear programming problem. The design of input shaped controllers, which are insensitive to modeling uncertainties, has been posed in the framework of a minimax problem by Singh ( 7...

... of measuring the payload motion. Therefore, this paper does not advocate feedback control, but rather command-shaping control that does not require sensors. Double-pendulum crane In this section, we examine a subset of crane manipulation tasks where the crane is used to move payloads that remain...

... | L | is 5,000 tracks. The length 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...

...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...
