Adaptive Neural Network Control

A bilateral neural network adaptive controller is designed for a class of teleoperation systems with constant time delay, external disturbance and internal friction. The stability of the teleoperation force feedback system with constant communication channel delay and nonlinear, complex, and uncertain constant time delay is guaranteed, and its tracking performance is improved. In the controller design process, the neural network method is used to approximate the system model, and the unknown internal friction and external disturbance of the system are estimated by the adaptive method, so as to avoid the influence of nonlinear uncertainties on the system.

Introduction Constant time delay is an evidence-based practice to teach sight word recognition to students with a variety of disabilities. To date, two studies have documented its effectiveness for teaching braille. Methods Using a multiple-baseline design, we evaluated the effectiveness of constant time delay to teach highly motivating words to three beginning braille readers with developmental disabilities. Procedural variations included a pre-teaching and assessment tool, a higher criterion for mastery, an increased number of trials per session, and remediated instructional feedback. Results A functional relation was established for all three participants. Students reached mastery in four to 12 sessions in less than one hour of instruction. Although the number of correct responses decreased over time, long-term maintenance was demonstrated. Discussion Results suggest that constant time delay is a promising strategy for teaching highly motivating words to early braille readers. Replication is required to establish constant time delay as an evidence-based practice for braille literacy. Implications for practitioners Practitioners are encouraged to incorporate constant time delay into a comprehensive literacy program with opportunities to generalize word reading to other contexts.

Fifth Grade Students

This study evaluated the effectiveness and efficiency of constant time delay (a near errorless learning procedure) in a small-group instructional arrangement. Three fifth-grade students with learning disabilities were taught to recognize multisyllabic basal vocabulary words. A multiple-probe design across behaviors (word sets) was used to evaluate the procedure. Following instruction on each word set, students were assessed on their ability to recognize their own target words, recognize observational words, spell both target and observational words, and define both target and observational words. The results indicated that the constant time-delay procedure was reliably implemented and was effective in establishing criterion-level performance for all students with extremely low error percentages.
