  • controllability and stabilizability of a networked control system with periodic Communication constraints
    Systems & Control Letters, 2011
    Co-Authors: Tatsuo Suzuki, Michio Kono, Nobuya Takahashi, Osamu Sato
    Abstract:

    Abstract This paper proposes a new model for a networked control system and considers its controllability and stabilizability. To control a linear time-invariant discrete-time plant via a bus with limited capacity, we introduce a hold device and a Communication Sequence which follows a given ω -periodic pattern. Incorporating the Communication Sequences and hold device into the original plant amounts to extending the original time-invariant state equation to a ω -periodic one which has the higher order. We assume that the Communication Sequence is admissible. It is shown that controllability and stabilizability of the plant are preserved in the periodic extended system under the assumption that the zeros of the Communication Sequence characteristic polynomial do not coincide with the eigenvalues of the plant.

  • three children with autism spectrum disorder learn to perform a three step Communication Sequence using an ipad based speech generating device
    International Journal of Developmental Neuroscience, 2014

    Abstract:

    Abstract Background Many children with autism spectrum disorder (ASD) have limited or absent speech and might therefore benefit from learning to use a speech-generating device (SGD). The purpose of this study was to evaluate a procedure aimed at teaching three children with ASD to use an iPad®-based SGD to make a general request for access to toys, then make a specific request for one of two toys, and then communicate a thank-you response after receiving the requested toy. Method A multiple-baseline across participants design was used to determine whether systematic instruction involving least-to-most-prompting, time delay, error correction, and reinforcement was effective in teaching the three children to engage in this requesting and social Communication Sequence. Generalization and follow-up probes were conducted for two of the three participants. Results With intervention, all three children showed improvement in performing the Communication Sequence. This improvement was maintained with an unfamiliar Communication partner and during the follow-up sessions. Conclusion With systematic instruction, children with ASD and severe Communication impairment can learn to use an iPad-based SGD to complete multi-step Communication Sequences that involve requesting and social Communication functions.
