Astrom et al. have proposed a new Smith predictor to control the process with an integrator and a long time delay. Though the method provides significant performance improvement, it fails to give effective tuning rules even when the integral constant is equal to 1. In this paper the method is extended to the general integrator/time delay process. A clearer and more logical design procedure is f...

Some progress has recently been made on migrating an existing distributed parallel discrete time simulator to a quantised discrete event architecture. The migration is done to increase the scale of the real-time simulations supported by the simulator. This however requires that the existing discrete time models be modified to work within the quantised discrete event environment. To this end the...

Persistent firing in response to a brief stimulus is a neural correlate of short-term memory in a variety of systems. In the oculomotor neural integrator, persistent firing that encodes eye position is maintained in response to transient saccadic eye-velocity commands. To a first approximation, firing rates in the integrator vary linearly with eye position. Thus, viewed across many cells, the p...

In this paper, we extend our clustering-based model order reduction method for multi-agent systems with single-integrator agents to the case where the agents have identical general linear time-invariant dynamics. The method consists of the Iterative Rational Krylov Algorithm, for finding a good reduced order model, and the QR decomposition-based clustering algorithm, to achieve structure preser...

This paper deals with voltage model flux estimators for speed sensorless induction motor drives. In order to eliminate the drift problems, the pure integrator of the voltage model is replaced with a first-order low-pass filter, and the error due to this replacement is compensated. An effective way to calculate the compensation is presented, and the compensation is carried out before the low-pas...

In this paper we present a PID+ backstepping controller, as a solution to the problem of coordinated attitude control in spacecraft formations. The control scheme is based on quaternions and modified Rodriguez parameters as attitude representation of the relative attitude error. Utilizing the invertibility of the modified Rodriguez parameter kinematic differential equation, a globally exponenti...

This paper proposes 128x100 array fingerprint sensor with the modified parasitic insensitive switched capacitor integrator. The modified parasitic insensitive switched capacitor integrator includes four switches to eliminate parasitic capacitance and transfer a generated charge. The proposed circuit also frees from the influence of skin resistivity, because the effect of the voltage drop throug...

In this paper the document as a container environment paradigm is explored. Utilizing this paradigm a platform neutral prototype control system design environment is being developed which uses a document as the user interface. This document acts as the integrator of various tools. A JavaBeans component based solution, allows the environment to be extended and modified as needed.

The problem considered is the design of a feedback system containing a linear, time-invariant, minimum-phase plant, whose parameters are known only within given bounds, such that the time-response of the system remains within specified limits. A quasi-optimal design, for given design constraints, is one which minimizes the effect of white sensor-noise on the input to the plant. Horowitz and Sid...
