In this paper, a new cluster fusion control strategy based on multisensor data fusion technique is presented from a perspective of industrial control application. The MSIF system consists of n sensors, n data-fusion nodes, a data-fusion database, and a expert knowledge database. Data-fusion mechanisms, including data coordination, data-fusion method and expert knowledge database, are discussed. A modified ART-2 neural network which can process analog data is applied to realize the data-fusion machine. Details about data acquisition and process, cluster-fusion control, interpretative mechanism and executive framework are discussed.

A frequency model of an OCXO (ovened controlled crystal oscillator) is suggested to implement a holdover algorithm in a DP-PLL (digital processing-phase locked loop) system. This model is presented simply with second order polynomials with respect to temperature and aging of the OCXO. The model parameters are obtained from experimental data by applying the LSM (least squares method). The holdover algorithm is simulated with the identified model using another experimental data.

We studied chemotactical behavior of an amoeboid multinuclear cell, Physarum polycephalum plasmodium. We experimentally observed that the small parts within a single organism showed different reactions under rather complex situations, unless the organism has no differentiation, and some adaptable behaviors of the individual have resulted from a temporary inadequate reaction of such a local part. We then propose an idea of animal local choice as a negation of a mechanical framework which assumes definitely decided one-to-one relations between an environmental stimulus and a reaction of an animal.

The parallel inverted pendulum system is one of the representative mechanical systems that have inherent instability characteristics, geometrical nonlinearities and dry frictions in actuators. Hence, it is sometimes desirable to apply a nonlinear multivariable control methodology. In the paper, a nonlinear quasi-linear quadratic Gaussian with loop transfer recovery (QLQG/LTR) control is proposed and experimented with on a parallel inverted pendulum system with dry frictions, in which system parameters such as amp gains are identified using genetic algorithms, and the dry friction is approximated to a quasi-linear model by random input describing function techniques.

This research is concerned with a new technology for the recognition of traffic sign from a motion picture. In order to realize a real-time position recognition, the genetic algorithm (denoted by GA) with search region limits is proposed. Through experiments, it is shown that new technology is sufficiently valid on real-time recognition to objects of motion picture.

A method to estimate the elastic moduli of a composite material by the sound that occurs at an impact on the composite material was proposed in the field of the material engineering. To estimate elastic moduli from the impact sound, we have to estimate the natural frequencies of the vibration of the material from the obtained time-series waveform. In this report, we show that the natural frequencies of the vibration of the composite material can be estimated by the bispectrum analysis more clearly than the power spectrum analysis.

In this paper, the group method of data handling (GMDH)-type neural networks with radial basis functions are proposed. Such networks can automatically organize themselves by using a heuristic self-organization method. In this algorithm, the network architecture can be automatically adjusted according to the complexity of the approximated nonlinear system. The number of hidden layers and the number of neurons in the hidden layers are selected so as to minimize an error criterion defined as Akaike's information criterion (AIC). Furthermore, various types of nonlinear combinations of variables are initially generated in each layer and only the useful combinations are selected by using AIC. In this study, the GMDH-type neural networks with radial basis functions are applied to medical image recognition of the brain. It is shown that this algorithm is simple and useful in medical image recognition of the brain.

The decoupling of the systems is to let the inputs and outputs correspond one to one, by performing the state feedback or the output feedback on the given systems. In this paper, we propose a method for decoupling the separable-denominator two-dimensional systems, and, we study about the realization dimension of the dynamical feedback and the dynamical feedforward performed for decoupling.

Presents an attempt to bridge the gap between theoretical successes of formal methods and their actual application in engineering of industrial automation systems. It deals with modeling and verification of distributed control systems developed according to the being developed international standard IEC1499. A new modeling formalism of Signal/Net Systems (SNS) is suggested, which is a place/transition net with usual token-flow arcs from places to transitions and vice versa, as well as with event arcs from transitions to transitions, and condition arcs from places to transitions which correspondingly force or enable transitions without passing tokens. The distinct feature of the SNS is that complex models they can be easily composed in the modular way from the component modules. This formalism is developed with particular view on the modeling of closed-loop plant/controller systems. The controller is modeled in a full deterministic and synchronous way (all the transitions fire according to the earliest firing rule) as a non-timed place/transition net while the model of plant might have spontaneous transitions and discrete-timed arcs to model time consuming processes. Verification of the controller/plant closed-loop system includes investigation of reachability problems for standalone controller and object, as well as proving safety properties for the closed-loop system.
