The focus of this paper is on the development of an input shaper/time-delay filter that permits the precise tracking of a ramp input, while eliminating residual vibrations. Zero phase error velocity tracking is often required in applications where moving parts have to be mated, such as manufacturing lines with high production output. A closed form solution to a pre-filtering technique is presen...

Binocular robots whose cameras can be independently directed require some mechanism for verging; i.e. aiming both cameras at a xation point. Since the desired vergence angle is directly related to target distance, some sensory cue to give depth information is required to the vergence system. The estimation of binocular disparity is a fundamental precursor to the depth estimation. Algorithms usi...

Due to its high-performance broadcast capability, -ary phase-shift-keying (MPSK) direct sequence code division multiple access (DS/CDMA) technique is widely used in terrestrial and satellite communications to provide wired/wireless services such as audio broadcasting, video broadcasting and high-speed data transmission. However, both coherent and noncoherent MPSK modulation schemes are sensitiv...

Abstract We consider tracking control for multibody systems which are modeled using holonomic and non-holonomic constraints. Furthermore, the may be underactuated contain kinematic loops thus described by a set of differential-algebraic equations that cannot reformulated as ordinary differential in general. propose strategy combines feedforward controller based on servo-constraints approach wit...

the control of fluidized-bed operations processes is still one of the major areas of research due to the complexity of the process and the inherent nonlinearity and varying dynamics involved in its operation. there are varieties of problems in chemical engineering that can be formulated as nonlinear programming (nlps). the quality of the developed solution significantly affects the performance ...
