This paper illustrates a method to develop a system diagnosis according to a vertical-rotating turbine based on the operating principle of the Darrieus rotor and to compare the results with a horizontal wind turbine. It is not easy to timely righteously estimate and evaluate the states. But it is very important for the safe operation in time domain system. The synthesis of this problem presumes that...
This work aims to develop a method for a system diagnosis regarding to an automatic screw or welding assembly line via the industrial robot that builds a constraint system with counterparts at the moment of working. The timely righteous estimation and judgment of the states is very important for the safe operation in time domain system. The synthesis of this problem presumes that all state variables...
The aim of this paper is to present a new method of designing a bilinear robust controller in a nonlinear system. This is an alternative and advanced method to control a shaking system with a heavy mass showing troublesome nonlinear effects. For this design procedure, a keel driven by a hydro-rotating driver is given. As the first step, the keel is physically modeled with a number of the limited masses...
Technical systems have almost nonlinear system behaviors. For the descriptions of their dynamical causes and effects on system, the physical information, which is concerned as a nonlinear mathematic model, has been used. But the corresponding equations are generally not easy to solve in complete form or their solutions are so complicated to see through the coherence. A common way to settle such a...
The goal of this paper is to describe an advanced method of a crack detection: a new way to localize position and to estimate depth of a crack on rotating shaft. As a first step, the shaft is physically modelled with a finite element method and the dynamic mathematical model is derived using the Hamilton principle; thus, the system is represented by various subsystems. The equations of motion of the...
