ROBUST STABILIZATION OF TWIN-ROTOR MIMO PLANT

The problem of MIMO system robust stabilization is considered for the twin rotor MIMO system mechanical plant, where nonlinear dynamics and parametric uncertainties were considered as disturbances. The proposed control law consists of two components: the linear component homogenizes a closed-loop system with a chosen degree of homogeneity; the homogeneous component stabilizes the system asymptotically or in finite time depending on the degree of homogeneity. Due to homogeneity properties of the closed-loop system in the absence of disturbances, the synthesized control law ensures input-to-state stability of the closed-loop system. In comparison with other works, presented approach of control synthesis for twin rotor plant does not require the decomposition of the system and/or consideration of the cross-link effects as disturbances. To confirm the effectiveness of the presented results, an experimental approbation was carried out on the mechatronic plant

Motion Profile Control Algorithm and Corner Smoothing Technique for Trajectory Optimization of High-Precision Processing

Processing accuracy in instrumental technology has always been of great importance. Producers of Computer Numeric Control (CNC) systems are constantly looking for novel solutions to achieve higher velocities and precision. However, most of the produced software algorithms are inaccessible to the general public. Hence the task to develop sufficient open source software arises. This paper aims to create a trajectory optimization algorithm, including feed rate control and a corner smoothing technique, which will allow effective high-speed and high-precision processing. It is intended to standardize the algo- rithm for application with both stepper and servo motor driven machines. The developed motion planning method is based on a cosine function to attain a smooth change of velocity that allows for vibration reduction. To achieve smooth corner processing, spline curves are applied to adjust the size and shape of a fillet and thus satisfy the required tolerance and maintain high velocities. The resulting algorithm is programmed and simulation tests are carried out. The final algorithm shows a smooth transition of velocities, which leads to vibration reduction and consequently to minimization of machining error. In corner smoothing the use of parametric curves demonstrates the ability to vary tolerance. As a result, a sufficient motion control algorithm is developed and can be used in CNC software

Mesh Networking in Cyber-Physical Production Systems: Towards Modular Industrial Equipment Integration

Ensuring uninterrupted interaction of modular industrial equipment units is one of the most important engineering tasks. The concept of Cyber-Physical Production Systems (CPPS) assumes that the distributed network should correspond to the current industrial process and be able to quickly reorganize it when changes occur. If composition of the equipment becomes more complicated, a standard topology with one central control node might get ineffective. This article describes the application of mesh-network technology to ensure the interaction of industrial devices and sensors included in the modular equipment. Virtual deployment of the network and a description network nodes interaction including new node registration in the dispatcher registry are given

The Concept of Taste in South Korea: Historical, Aesthetical and Philosophical Aspects

The focus of this paper is on the Korean aesthetic model of taste. In order to investigate the origins of aesthetics in Korea and its current place in Koreans’ lives, it analyzes the key concepts of the Korean aesthetics and spiritual aspects of life for Koreans. In a way to exemplify this cultural system, traditional Korean food is presented as a conceptual representation of the aesthetic experience. Its role in integrating different aspects of meanings and values in everyday lives of Koreans is also discussed. The research subject is studied through the complex lenses: its association with both the gastronomic taste, which comprises organoleptic perception and aesthetic judgements, and the semiotic aspect of culture, represented by basic units thereof – words. The optics of the interdisciplinary outlook of this method suggests a new approach to viewing Korean aesthetic of taste. The research shows that scientific approach to aesthetics was first adopted in Korea in the 1930s under the cospicuous cultural influence of the Japanese colonial rule; the ideas formed at that time still remain important aesthetic concepts. The study proposes that meot should be viewed as the most important and representative concept in Koreans’ everyday aesthetic experience. The cultural and historical analysis of Korean gastronomic culture suggests there is a number of specific cultural and cosmogonic meanings that were typical of the royal cuisine during the Joseon era and demonstrates how certain Korean dishes are endowed with aesthetic and existential values today
