This paper mainly focuses on establishing the stability conditions of the double exponentially weighted moving average (d-EWMA) controller with metrology delay when the process experiences a general disturbance and analyzing its control performance under some typical types of process disturbance. The necessary and sufficient conditions for stability are established by Routh-Hurwitz criteria. It has...
Dynamic taint analysis technique plays an important role in tracking the input data's trace in an executing program, and it has been widely used in program analysis method, such as information-flow analysis and dynamic slicing. However, most of the tools implementing dynamic taint analysis only consider the data dependence propagation and neglect the control dependence. In this paper, we presents...
The double EWMA (exponential-weighted-moving-average) controller, as one kind of R2R (Run to Run) controller has been widely used in the industrial process, especially in semiconductor manufacturing. In this paper, two forms of the most popular double EWMA controller are analysed and compared in terms of the stability conditions and long-run performance. We point out their own advantages and disadvantages...
To achieve the integration of failure reporting, analysis and corrective action system (FRACAS) with the main process of product design, an implementation model was proposed based on product data management (PDM)methodology. The model was built on the basis of PDM product objects and process objects, and depicted the product failure data and the closed loop control process in FRACAS with the object-oriented...
