We propose a method of designing a less conservative reduced-order controller by using a genetic algorithm. Since it is difficult to search for a reduced-order controller directly, we search for the full-order controller whose reduced-order controller has the approximate performance of the H/sub /spl infin// optimal full-order controller by adopting controller parameterizations. Then, it is reduced by a certain reduction technique. We propose a coding that is to search only a set of all optimal full-order controllers, since the desired full-order controller is expected to be one of numerous optimal full-order controllers. In order to show the effectiveness of the proposed method, the numerical example is given.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.

Because of the development of the Internet infrastructure and the low cost of deployment, implementing storage over IP has become a trend. While networked storage brings economy, it also raises performance concern. In a typical distributed Web system, I/O requests from clients users may be satisfied by many different parties along the I/O path from front-end clients to back-end storage systems via proxy and Web servers. To improve the performance, we need to identify the I/O distribution pattern along the path. This paper analyzes the I/O distribution along the I/O path of a distributed iSCSI RAID system by using kernel counters and profiles how the I/O requests are satisfied at different levels of the proxy server and storage system, which is useful to identify the performance bottleneck.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.

The orthogonal spectral pairs can be utilized as in-phase ('I') and quadrature phase ('Q') signaling waveforms for use in data transmission. This paper describes the origins of these signaling waveforms and the delayed-orthogonal adaptation necessary to preserve phase continuity at the switching boundary. Delayed-orthogonal signaling for wireless channel transmission exhibits spectral properties nearly void of message-driven switching artifacts. This characteristic permits good spectral control regardless of the message content; which allows high-density frequency domain multiplexing utilizing low guard-band separation, with channel bandwidth on the order of the bit rate. Delayed-orthogonal signaling permits subcarrier injection that is well isolated from the message signal modulation. The subcarrier signal provides a coherent reference for demodulation, gain control, and additional signaling.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.

The coupled flux path configuration has a non-diagonal inductance matrix and is operated with synchronous excitation, whereas the uncoupled flux path configuration has a diagonal inductance matrix and is operated with switched excitation. Constrained optimization methods are used to investigate the force production capabilities of both magnetic configurations. The specific measure of performance emphasized here is the ratio of current-limited ripple-free force to moving mass or, equivalently, the maximum achievable fully controllable acceleration. This focus is motivated by robotics applications, e.g. component placement machines used in electronics assembly.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.

Using this concept and the composition product, an explicit relationship is then derived between the formal Laplace-Borel transforms of the input and output signals. This provides an alternative interpretation of the symbolic calculus introduced by Fliess to compute the output response of such systems. Finally, it is shown that the formal Laplace-Borel transform provides an isomorphism between the semigroup of all well defined Fliess operators under composition and the semigroup of all locally convergent formal power series under the composition product.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.

The learning models are derived from discrete time functions often used in digital control system design. The techniques are successful to detect regions with different or poor light conditions and can be applied to images with occluded or noisy objects. In addition, the approach can be used to locate objects in a scene. The developed algorithms can also be integrated on a single monolithic integrated circuit or implemented as an embedded system for real-time applications.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.
