This paper proposes a new fixed-point computing method for motion profile generation. When parameters have wide ranges, floating-point computing usually is used for accurate computation; however, this method increases execution time. In the proposed method, by considering input data, optimum fraction lengths are determined for different parameters. In this way, the fixed-point computing offers an accurate computation in a minimum execution time. Experimental results show the performance of the proposed method.

The work deals with usage of classical PID controller to maintain balance between electricity consumption and production using concepts of smart grid and virtual power plant. Aggregated control of large groups of thermostatically controlled loads can be used for ancillary services provision. The focus is on secondary control and peak-shaving, which are a part of the power balance problem. Calculation of PID controller parameters are based on the localization method. The main idea of the localization method is using a derivatives vector of the controlled variable for manipulated variable calculation. The highest derivative implicitly contains full information about plant's state at the current moment. The dynamics of individual building with heaters is described by second order equivalent thermal parameters (ETP) model. The obtained results show that aggregate response of large population of electrical space heaters can meet the requirements on both of the problems. Nevertheless, there are still a lot of issues remaining open: influence of the hysteresis parameter, and using suitable sampling time in order to lower demand on the communication infrastructure.

IEEE International Conference on automation Science and engineering

This paper addresses the problem of flocking of mobile robots by bounded feedback. A control problem is formulated with the multiple goals: velocity consensus, collision avoidance, and cohesion maintenance. The flocking protocol is then obtained by means of control design. Particularly, a Lyapunov-like function is presented, the velocity control is designed to achieve coordination and linear speed consensus, and the steering control is designed for consensus on orientation. The convergence is verified via Barbalat's lemma. Simulation results with a group of mobile robots are presented to show the effectiveness of the proposed flocking control.

Pigonia Str. 1 Rzeszów35-310 Poland Department of Power Engineering and Automation of Agricultural Processes Faculty of Production and Power Engineering University of Agriculture in Krakow Poland Balicka Str. 116B Kraków30-149 Poland

The main goal of our research is to build the ontology of places in Poland covering a variety of aspects of places, mainly administrative and socio-economic. The ontology is being implemented using the OWL 2 Web Ontology Language. In the created OWL ontology, we can distinguish two kinds of classes, primary classes exactly defined in the ontology as well as secondary classes defined over the ontology on the basis of primary classes and properties of individuals considered in the ontology. We show how to use rough sets to approximate secondary classes by means of primary classes in the created ontology. Rough set approximations enable us to extract some useful knowledge about places.

The axle temperature of the high speed train is the most direct reflection of the train operating conditions while it is also affected by many factors. The factors which significantly affect the axle temperature are screened out by using the stepwise regression analysis and the prediction equation of the axle temperature is established, so as to compare the predicted data and the measured data. The validity of the coefficients in the equation is verified through R-squared, F test and T test. The experiment shows that R-squared is between 0.81 and 0.93, indicating a high degree of fitting prediction equations, and F test results show that the overall equation is significantly better. The results of T test indicate that the velocity, the carrying capability and the ambient temperature have significant influence on the change of axle temperature. But the traction and the power of traction have less effect. The result shows that this method can reflects the variation trend of axle temperature, which can provide support to the operation and maintenance of axle.

International Workshop on Variable Structure Systems, VSS

The certainty-equivalence super-twisting controller (CESTA) combines approaches from variable structure and adaptive control. In this paper, an improved variant of this algorithm is presented that resorts to a recently introduced Lyapunov function for the super twisting algorithm, establishing a novel continuous adaptation law. These controllers are beneficial for systems that are affected by structured and unstructured uncertainties. It is demonstrated that the combination of sliding-mode and adaptive control methodologies allows to relax the boundedness condition, known from the super twisting algorithm. In comparison to earlier work, asymptotic stability of the system states may be shown while requiring relaxed conditions on the structured uncertainty. The effectiveness of the proposed algorithm is shown with a simulation example.

The transition between the power market competition and these emerging renewable power system alternatives (wind turbines, solar plants, micro-turbine), has awaken a great deal of interest for distributed power generation. Distributed Generation comprise in low power generators (typically lower than 50 MW), installed within the area of the main power consumption to ensure the growth of the existent distribution network and to satisfy the consumer's needs. © 2014 IEEE.
