Since plastic products are with the features as light, anticorrosive and low cost etc., that are generally used in several of tools or components. Consequently, the requirements on the quality and effectiveness in production are increasingly serious. However, there are many factors affecting the yield rate of injection products such as material characteristic, mold design, and manufacturing par...

Sensor failure detection and identification has been considered as an important issue, particularly when the measurements from sensors are used in the feedback loop of a control law. Kalman filters and Luenberger observers have been widely used to generate signal redundancy by means of state estimation. Dedicated observer scheme and generalized observer scheme are the older methods available fo...

In this paper, a fault detection and diagnosis approach adopted for an input-output feedback linearization (IOFL) control of induction motor (IM) drive is proposed. This has been employed to detect identify the simple mixed broken rotor bars static air-gap eccentricity faults right from start its operation by utilizing advanced techniques. Therefore, two techniques are applied: model-based stra...

Rotating equipment is considered as a key component in several industrial sectors. In fact, the continuous operation of many machines such sub-sea pumps and gas turbines relies on correct performance their rotating equipment. order to reduce probability malfunctions this equipment, condition monitoring, fault diagnosis systems are essential. work, novel approach proposed perform based permutati...

This study, fundamentals of fuzzy block theory, and its application in assessment of stability in underground openings, has surveyed. Using fuzzy topics and inserting them in to key block theory, in two ways, fundamentals of fuzzy block theory has been presented. In indirect combining, by coupling of adaptive Neuro Fuzzy Inference System (NFIS) and classic block theory, we could extract possibl...
