On-line Tool Wear Classification in Unmanned-machining Environments

One of the most important features of the modern ma ch ining system in an “unmanned“ factory is to change tools that have been subjec ted to wear and damage. An integrated tool condition monitoring system composed of multi-sensors, signal processing devices and intelligent decision making pla ns is a necessary requirement for automatic manufacturing processes. An intellig ent tool wear monitoring system will be introduced in this paper. The system is equipped with power consumption, vibration, AE and cutt...     

模糊控制实现温度调节方法的应用研究

提出了模糊控制器的模型和模糊算法，并把它应用到温度控制系统中去，得到了良好的控制效果。     

A role—Based Fuzzy Assignment Model

It's very important to dynamically assign the tasks to corresponding actors in workflow management system, especially in complex applications. This improves the flexibility of workflow systems. In this paper, a role-based workflow model with fuzzy optimized intelligent assignment is proposed and applied in the investment management system. A groupware-based software model is also proposed.     

“不精确概念的表示理论”一文中两个命题的修正

指出了“不精确概念的表示理论 (Ⅰ ) ,(Ⅱ )”一文中命题 3.3中性质 5 ,X≈αR Y XUYC=U ,X∩YC=Φ和命题 2 .1存在的 2个错误 ,并给出了相应的修正 .     

A Novel Robust Adaptive Fuzzy Controller

For a class of continuous-time nonlinear system, a novel robust adaptive fuzzy controller is proposed by using of Lyapunov method. It is proven that the control algorithm is globally stable, the output tracking-error can convergence to a domain of zero under the assumptions. As a result, the system controlled has stronger robustness for disturbance and modeling error.
