In order to control complicated production plants, distributed process control is a powerful approach. In the development of a distributed process control system, it is difficult to develop its software because distributed controllers complicatedly interact with each other. For that reason, the function block model, which is the specification language for distributed process control logic, is being standardized in IEC61499-1. A distributed process control programming tool for function block description is proposed. It is possible to describe control programs hierarchically by using function blocks. The GUI of this tool supplies multi-windows which can simultaneously display function blocks on different hierarchical levels. In this tool, inputted programs can also be verified by a simulation. This tool is applied to the control program description of an automatic carrier system. It has been confirmed that the control program is completely described and simulated by using this tool.","PeriodicalId":119106,"journal":{"name":"1999 7th IEEE International Conference on Emerging Technologies and Factory Automation.

Different velocity sensing techniques and methods are discussed. One of them is chosen and implemented, fulfilling the main objectives proposed. The first objective is to reserve the computational power of the DSP for control tasks, avoiding the processor's use for sensing tasks like velocity sensing. The second objective is to get the maximum accuracy over a wide velocity range. There are two error sources: quantification effects due the digital system and errors in the encoder channels due to encoder mechanical and/or electronic imperfections. Both error sources have been considered, obtaining an improved accuracy compared with other actual methods based only on quantification effect reduction.","PeriodicalId":119106,"journal":{"name":"1999 7th IEEE International Conference on Emerging Technologies and Factory Automation.

We present a new geometrical analysis of rigid body transformation parameters from properties of reflected correspondence vectors. Based on this analysis, we propose a novel algorithm to calibrate transformation parameters of 3D objects in a fast production line of filter components. The algorithm performs a rigidity analysis from range images acquired from two cameras, making full use of distance and angle information providing a closed form solution to all parameters of interest. The method is used in conjunction with a decision support system where components falling outside specified thresholds are to be rejected. For a comparative study of algorithm performance, we also implemented a well known procedure for rigidity analysis based on quaternions. Experimental results demonstrate that our novel algorithm has a number of advantages over the quaternion method and that its performance is superior or similar to the quaternion method.","PeriodicalId":119106,"journal":{"name":"1999 7th IEEE International Conference on Emerging Technologies and Factory Automation.
