This paper introduces the design of a handheld musical input device that produces control data by measuring, and analyzing, the resonances of carefully tuned pipes. The device provides input control information to several virtual reed instruments running in parallel, responsible for producing the sound. Inspired by the khaen, a musical instrument from Northeast Thailand and Laos, the controller...

This paper considers a design problem of controllers for wire-less vehicles in the developed networked control system. The developed system consists of a wire-less vehicle and some computers which configure a computer network. The vehicle is controlled over the computer network. One of the computers is a router which has an active queue management mechanism to keep the queue size constant and t...

Video segmentation techniques have so far been widely used for a range of applications such as MPEG-4 encoding and automatic surveillance system. Historically, algorithms developed for such applications have been restricted to less complex and robust solutions implemented on computers. As a consequence, most systems were either too slow or succeeded under very controlled situations. In this pro...

Modeling fault behaviors such as fault occurrences and active/benign durations is an essential step to the design and evaluation of fault-tolerant controller computers. We use a beta-binomial distribution to model fault occurrences both in the presence and in the absence of environmentally-induced (thus common-cause) faults. A multinomial distribution is used to model fault active durations. Th...

This paper mainly investigated a sampled-data control approach to deal with the stabilization problem of Networked Control Systems (NCSs) with packet losses and bounded time varying delays. A new Lyapunov-Krasovskii functional candidate is constructed to analyze the stability of the overall system with bounded random packet losses and time varying delays. As a result, corresponding stabilizing ...

With today’s wireless technologies, such as BlueTooth and IEEE 802.11, connecting handheld devices and conventional computers together is no longer an occasional event for synchronization. Instead, devices can be frequently in close, interactive communication. Many environments, such as offices, meeting rooms, and classrooms already contain computers, and the smart homes of the future will have...

This paper develops a new estimate-based dynamic event-triggered output feedback controller for networked control systems subject to nonlinear uncertainties. Specifically, based on the sampled-data, discrete-time and event-triggering condition are proposed by virtue of domination technique. The method is easy implement in digital computers due form discrete time. Under method, selection regions...
