Artificial intelligence techniques have been used for carbon monoxide and oxygen low cost sensors signal processing in biomass combustion. Considering a large scatter of the measured data two approximation tools using artificial neural networks have been tested for approximation of carbon monoxide emissions dependence on oxygen concentration in the flue gas: AForge. Neuro library and Neural Network Fitting Tool of Matlab. The comparable results of approximation have been obtained by testing of both approximation tools on the off-line measured data.
The modern method for aluminum production is electrolysis, which extracts molten aluminum from a mixture of cryolite and alumina. During the aluminum electrolysis process, due to density differences, the molten alumin...

This paper presents a dynamic model representing the rigid body motion of a four wheel steer and four wheel drive (4WS4WD) vehicle which also takes into account the rotational dynamics of the individual wheels as well as the tyre terrain interactions. It also presents a modified pursuit algorithm taking into account the kinematic constraints as well as a decentralized wheel propulsion control system. Simulation results are presented to show the model validation and the successful implementation of the path tracking algorithm.

It's difficult to achieve the target temperature control for the continuous casting billet with regular voltage control curve in electromagnetic induction heating process of hot rolling production line. This paper first analyzed billet electromagnetic induction heating mechanism, determined the factors which caused the billet temperature rise, and applied artificial neural network to establish the temperature prediction model. Then, with decoupling the relationship between the billet heating conditions and the voltage curve, this paper applied the random search method to optimize the voltage control curve based on the prediction model. Finally, the actual trial showed that the optimized voltage control curve could achieve a high precision control of the target temperature

The main contribution of this work is the application of delay-dependent adaptive control techniques to control nonlinear continuous stirred tank reactor (CSTR) model with state delay. The delay-dependent adaptive control problem is first formulated and stabilizing adaptive control algorithms are developed and then applied to the CSTR process model. The CSTR model includes a nonlinear perturbation which is assumed to have a norm that is bounded by a scaled norm of the state vector. Here, we consider two cases where the weight of the state norm is assumed to be known and unknown. Simulation results show the efficacy of the delay-dependent adaptive control schemes in controlling the CSTR nonlinear process model.

Selfreconfigurable robots are built on a set of elementary modules. Actually the different works in this field are not compatible. This can be seen as an useless dispersion. We propose here an analyse of the conditions that are necessary to give to this field some common rules to build component that could "easily" work together.

This paper presents a robust torque, flux and speed controller's design method for permanent magnet synchronous motor (PMSM) drive using Direct Torque control (DTC). A simple algorithm is presented to adjust the parameters of torque, flux and speed controllers. This mini-max optimization problem is solved using Hybrid Bacteria Foraging-Particle Swarm Optimization Approach (BF-PSO). The solution thus obtained is global optimal and robust. The proposed technique eliminates common problems including;torque ripples, low speed and integration drift. As well as it characterized by fast tracking capability, minimal overshoot responses, and robust to load disturbances and low speed operation. Results prove the effectiveness and viability of the proposed technique.

To meet rising demands of synchronization precision in distributed nodes in LAN network, a specialized scheme is proposed based on the intermediate-level modeling for initial synchronization and periodical resynchronizations with basic concurrency control and tight bounds. Several representative threads are designed and well scheduled with definite and thorough functional partitioning inside to create a fast and efficient circumstance for communication between nodes. An experimental realization based on RT Linux kernel and corresponding measurements are accomplished. The results indicate that in a small-scale distributed environment, the nodes are able to be well synchronized during in the long run with hundreds of resynchronizations and the deviations are significantly limited in a reasonable range. The proposed scheme effectively promotes the performance of dock synchronization in the LAN network.

"Complex networks" is the term for a research area where complex systems are modeled by a graph to analyze their structural behavior. They are mostly used in the areas of social sciences, biology and physics. For example, complex networks are a proper method to describe and analyze the non-trivial characteristics depending on the interconnection in a society or between human organs. In the context of computationalintelligence, this paper introduces an idea to transfer the methods of the area of complex networks to technical systems, and, furthermore, enhance them to permit analyzing dynamic behavior. As a basis for the method transfer a transfer-function-based graph is presented which allows modeling technical systems in the same way as complex networks. The potential to detect dynamical behavior, in addition to structural behavior, is demonstrated by a new algorithm that detects inverse response in interconnected systems based on methods of complex networks. The introduced algorithm provides a qualitative answer if inverse response behavior is possible between a pair of input and output of a system. Finally, two case studies are used to demonstrate the algorithm.
