Acute disabilities always need different types of assistive devices in their daily life. Usually, each of these devices is designed for only one particular usage. Because of this, an acute disable may have to use a joystick to manipulate his wheelchair, used a mouse to control computer, or used a keyboard to control movement of mechanical arm. Thus no consideration of interrelations among these tools was discussed. In 1990, the technical working committee 173 (TC-173/sc-1/wg-7) of ISO (International Organization for Standardization) using serial interface protocol (ISO 7176-7) to integrate all types of assistive tools for the disabilities. At the same time, the European Common Commission funded the research for M3S interface (Multiple Masters Multiple Slave). It provides the disable a concrete integral control for his movement, working, environment control and communication. This is an integrated intelligent real time control capability protocol. It is a plug and play device interface. We design and develop a M3S protocol using TMS320F243 DSP chip. The system was tested for I/O control and it meets the equipments supported by the M3S working group. Thus, it would bring lots of comforts for the disable.

As most controllers of the carton samplemaker using Industrial Personal Computer (IPC) architecture, its price is relatively expensive. Aiming at the actual situation of the high cost, low openness and big demand of the carton samplemaker, through the analysis of the control characteristics of it, the embedded Numerical Control (NC) platform based on the Advanced RISC Machines (ARM) and Digital Signal Processor (DSP) hardware architecture for carton samplemaker is designed. The overall framework of the platform and steps of the design are given in this paper. Windows CE embedded real-time operating system is adopted in the software design, and on this basis, the carton samplemaker applications is developed, which is mainly in charge of the motion control of the equipment and tasks management. The platform not only achieves the goals on real-time control, good speed and accuracy, but also has friendly operability. Finally, the introduction of the new dual-core chips gives a revelation on the future development in carton samplemaker.

We propose an objective parallel computation/control method, developing the following to solve conventional problems and installing a controller on a robot with links decomposed to objects: 1) parallel calculation for twodimensional link dynamics, 2) downsizing of a high-speed controller using a digital signal processor (DSP), 3) a common robot control library, and 4) parallel calculation control of a multilink system. Evaluating parallel computation/control using the DSP, we verified fine compact controller efficiency in real-time control of multi-DOF systems and control performance comparing overall system control by linear quadratic optimal control.

This paper analyses the status of aquiculture in China and gives out some of its potential problems. In order to over these problems, Industrial fieldbus and Intranet technology are used in this paper to achieve the hardware and software design, as well as control strategies for factory aquaculture. It applies WEB server, database server and browser to establish the management platform for environment control and production process. The whole system was successfully verified at Zhenjiang production base. Through a real-time control of dissolved oxygen, temperature and PH in pond, this system stabilizes these parameters at each own optimum values, and dramatically improves the overall productivity. The test results show that this system is easy-operated and user friendly, it provides a direct and practical measure for aquiculture, and saves energy as well.

Multi Agents

This paper presents an  innovative Multi-Agent approach related to an advanced real time control  of flexible manufacturing systems. The proposed architecture is based on the paradigm of Distributed Intelligence and Multi-Agent Systems. The developed  Multi-Agent prototype system integrates  the following functions: Scheduling, dispatching, monitoring and error handling. A new negotiation protocol for manufacturing systems is presented in this paper. The purpose of this protocol is to assign dynamic operations to the resources of the Manufacturing System in order to accomplish the proposed tasks. This protocol is able to deal with exceptions.

Most modern fighter aircraft are multi-role by design and rely heavily on a number of systems that are computer controlled in real time for achieving the most optimal performance. This paper presents three important real time control systems designed for the Indian Light Combat Aircraft. These are the flight control system, the anti-skid brake control system and the environment control system. Design objectives for these systems along with a description of their various hardware elements, software architecture and design concepts have been presented here. All the systems house extremely critical functions during different phases of flight, and so are designed for high degrees of reliability and extremely low failure probabilities. The concepts adopted for redundancy management, failure identification and failure handling are also presented.
