  • In this paper, we suggest a new quasi-sliding mode condition with a wighting factor which guarantees all the states to reach switching planes and improves the convergence of the state trajectories. The result of computer simulation shows that by the suitable selection of a weighting factor, all the state trajectories reach switching planes and enter the sliding mode having the property of the insensitivity to parameter variation and disturbances.

  • In this paper, we studied a now VDSL frequency plan mode 6 for improved\ulcorner symmetric 10MDSL service. The frequency plan 998 for asymmetric and frequency plan 997 for symmetric have arc not optimally designed for 10MDSL service. To improve reach and rates of 10MDSL, we proposed for a now frequency plan. According to the results of our simulation studios of newly Proposed mode 6 frequency plan which compared to plan 998, 997, and ethers[2], the new scheme gives an improved performance in rates and reach.

  • Due to high payload capacity and high length-to -cross-section ratio requirements, long-reach manipulator systems are expected to exhibit significant structural flexibility. To avoid structural vibrations during operations, various types of input shaping filtering methods have been investigated. A robust notch filtering method and an impulse shaping filtering method were investigated and implemented. In addition, two very different approaches have been developed and compared. One new approach, referred to as a
