Now the CAN(controller Area Network) is using electronic modules as a serial communication which is very robust to noise. Especially the CAN is using for automotive part that very popular in which automotive electronic control module, engine controller unit, sensor modules, etc. but the CAN has the order of priority to linking node and also has fault confinement so using in these features that is applied to in factory automation product line. The CAN communication is basically very robust to electric noise so varied applying to others part. In this paper, we suggest to CAN interface for embedded system that is possible for error detection using two CAN nodes on Hi-speed, full-CAN.

The Controller Area Network (CAN) is being widely used in real-time control applications such as automobiles, aircraft, and automated factories. Unfortunately, CAN, in its current form, is not able to either share out the system bandwidth among the different devices fairly or to grant an upper bound on the transmission times experienced by the nodes connected to the communication medium as it happens, for instance, in the token-based networks. In this paper, we present An Application Layer Design for Humanoid Robot in the CAN. Besides introducing the new algorithm, this paper also presents some performance figures obtained using a specially developed software simulator and experimentation for composition of CAN which uses JTAG mode of a parallel debugging., while the behavior of the new algorithm is compared with the traditional CAN systems. in order to see how effective they are.

This paper presents an idea of implementation of many semiconductor equipments. The idea is a new design methodology of the Networked Control Systems (NCSs) using CAN (Controller Area Network) will be discussed. The Distributed Control Systems (DCSs) is very useful to control multiple systems that have a distance to communicate. The CAN protocol is very strong to noise, also provides the user with many powerful functionality. Only one communication line (BUS) is used, so that a control and a maintenance of those systems are very easy. This paper is concerned with the speed control of multiple DC motors using CAN Protocol. Experimental systems are made to validate effectiveness of the systems. The results of the experiment show that the NCSs using CAN has excellency in real time control.

In recent years, a lot of industrial equipments have serial communication channel such as FieldBus (CAN, Profibus, etc.) or Ethernet that provides real time communication between industrial equipments. Theses applications include gantry crane, robot, chip mounter, etc.. In this paper, we discuss the synchronization technique for networked multi-motor systems where controllers (commercial servo amps) are distributed and interconnected by CAN (Controller Area Networks). We first describe the equivalent model for the individual servo-amp and motor using the frequency response. We design the $H{\infty}$ controller for motion synchronization. Finally, the synchronization technique using the equivalent model and the $H{\infty}$ controller is verified by the simulation and the experiment.

Most of existing integrated remote controllers can control only a group of home appliances made by the same manufacturer. And they cannot monitor the status of home appliances since they are based on analog RF(Radio Frequency) signal and operate in a uni-directional manner In this paper, we propose a software framework for a hi-directional universal remote controller(URC) which monitors the status of home appliances in Wireless Personal Area Network(WPAN). The URC can handle the control and status messages which consist of a command with related arguments. When a user wants to control any home appliance, the URC can be dynamically configured to its dedicated remote controller by generating a GUI according to its profile. Any other devices which have a capacity for understanding the profile from the controlled devices can play the same role of the URC.

In this paper, several network nodes that are essential elements of create a distributed system have designed and developed using CAN(Controller Area Network). The network nodes consist of RISC(Reduced Instruction Set Computer) CPU and CAN controller. By these two parts used, the network nodes have merits that are fast process speed, stable communication, cheapness and others. The most important quality that is the designed network node can be applied to various network control systems.

In the case of construction equipment, internal wiring has a very complicated structure such as an electrical wiring and hydraulic equipments. Because of these complex wiring, a lot of time is spent on maintenance and equipment manufacturing. In this paper, we design and implementation of the high-reliability PLC(Power Line Communication) -CAN(Controller Area Network) communication module to reduce electrical wiring of the construction equipment.

The load frequency control of power system is one of important subjects in view of system operation and control. That is even though the rapid load disturbances were applied to the given power system, the stable and reliable power should be supplied to the users, converging unconditionally and rapidly the frequency deviations and the tie-line power flow one on each area into allowable boundary limits. Nonetheless of such needs, if the internal parameter perturbation and the sudden load variation were given, the unstable phenomenal of power system can be often brought out because of the large frequency deviation and the unsuppressible power line one. Therefore, it is desirable to design the robust neuro-fuzzy controller which can stabilize effectively the given power system as soon as possible. In this paper the robust neuro-fuzzy controller was proposed and applied to control of load frequency over multi-area power system. The architecture and algorithm of a designed NFC(Neuro-Fuzzy Controller) were consist of fuzzy controller and neural network for auto tuning of fuzzy controller. The adaptively learned antecedent and consequent parameters of membership functions in fuzzy controller were acquired from the steepest gradient method for error-back propagation algorithm. The performances of the resultant NFC, that is, the steady-state deviations of frequency and tie-line power flow and the related dynamics, were investigated and analyzed in detail by being applied to the load frequency control of multi-area power system, when the perturbations of predetermined internal parameters. Through the simulation results tried variously in this paper for disturbances of internal parameters and external stepwise load stepwise load changes, the superiorities of the proposed NFC in robustness and adaptive rapidity to the conventional controllers were proved.
