In the present paper a simple anti-reset windup solution is derived for TITO PID control based on the ideal decoupler. Difficult examples are used to demonstrate performance of the proposed anti-reset windup TITO controller. The first example is the model of a typical industrial process, with significant multivariable interactions, a non-self regulatory nature, non-minimum-phase behavior and with integral action in the decoupler. The second example is a stable process with high relative gain array RGA of 13.7 in the nominal operating regime and significant multiple dead-times. An anti-reset windup solution is proposed also for inverted decoupling. Closed-loop system responses, obtained by antiwindup implementations based on the ideal and inverted decoupling, are compared on a stable process with an RHP zero and multiple time delays.

In this paper, a software supported DC voltage calibrator is presented, requiring a standard programmable signal generator, a digital voltmeter, and some free software components. After detailed analysis of the programmable signal generator applying an automated process, it is concluded that intrinsic precision is insufficient for the generator to be used as a voltage calibrator. Furthermore, offline calibration techniques as polynomial interpolation and lookup table compensation are ruled out due to the generator reference instability over temperature and time. As a solution, a closed loop method based upon a voltmeter and a control software thread is proposed. The method is verified experimentally.

This paper considers how selection techniques applied in an orthogonal frequency division multiplexing (OFDM)-based wireless local area network (WLAN) system influence on a system performance. Namely, ergodic and outage capacity of the considered system are simulated in order to determine the most adequate receiver design for certain WLAN environment.

A Neuro-Adaptive Internal Model-based Control (NAIMC), using the Fast Clustered Radial Basis Function Network (FCRBFN) equipped by the Stochastic Gradient Descent (SGD) learning algorithm is proposed to control the nonlinear plant with slow dynamics. As a first step in this design approach, the classical feedback controller is applied to improve the overall dynamic characteristics of the obtained local closed loop. Such local loop is further on considered as an equivalent plant to which the NAIMC can be applied. The improved characteristics of the equivalent plant can be usually obtained by some kind of the PD control law and we used this approach at the NAIMC design of the nonlinear slow process. To achieve a zero-steady state error in cases of the piecewise constant changes of the reference and disturbance at output of the plant, we applied the method of Gain Scheduling (GS) for adjusting the gain of the Q controller in the NAIMC based structure. We illustrate the performance of the proposed NAIMC design using simulation results for the control of a double tank system.

This paper presents an overview and systematic analysis of various design methods for obtaining the observer corrective action gains for stable and precise estimation of synchronous reluctance motor speed. The structure of the reduced order observer consider stator current and extended back electromotive force vectors as observer state variables in stationary reference frame and utilize robust correction mechanism for speed estimation of synchronous reluctance motor. The effect of change in machine inductances on observer estimation accuracy is also discussed. Evaluation is given through simulation results of considered synchronous reluctance motor drive.

Digital flat-panel radiography detectors have become a standard part of modern digital radiography systems. Performance of a detector can be evaluated through three major indicators: noise, contrast and spatial resolution. Signal-to-noise ratio was employed to evaluate noise presence, contrast-to-noise ratio was utilized for contrast characteristic estimate while modulation transfer function and visual inspection of resolution phantom image were used for spatial resolution evaluation. In this paper, we present an extensive comparison of eight different flat-panel detectors using aforementioned evaluation methods. Comparison results are presented both numerically and graphically.

The aspects of the protection of the environment and the expected increased demand for electricity imposed improving technology for the production of energy from renewable sources (with a drop in the price of these technologies) and the introduction of economic objectification in energetic over the market. An important issue when making investment decisions related to the construction of new power plants based on renewable energy sources is to make optimal selection of technologies for the best integration of new power plants in the electricity system, taking into account the physical limitations (voltage level, load flow ...) network. Standard tools for energy optimization HOMER, no possibility of network analysis and therefore need coupling with some of the tools for network analysis, for example. DIgSILENT, in order to respect the physical limitations of the network. These additional restrictions, imposed by the network, change the order of the economically optimum ranked variants proposed by the software-tool HOMER. This work its part of the methods' formulation explains the methodology and initial implementation of the related set of tools HOMER-DIgSILENT, and then, through the example of the analysis of the possible construction of new power plants which use renewable energy sources (photovoltaic power plant) connected to the transmission electricity network, considers optimal planning variants taking into account the market. The integrated parametric tool is considered to be an integrated, parametric tool be of importance to decision-makers, consultants and contractors, and will have significant commercial potential.

This paper presents the implementation details of a power flow method for unbalanced three-phase distribution networks. The proposed technique utilizes the current injection (CI) method for power flow calculation and considers the modeling of unbalanced loads, load tap-changing (LTC) transformers, and shunts capacitors. Compensation currents are employed for modeling changes in the settings of LTC transformers and shunt capacitors. The compensation currents eliminate the need to re-factorize the admittance matrix during the iterative solution of the power flow equations and provide a computationally efficient and fast method. The proposed method has been tested on the modified IEEE 13 node test feeder, and the presented results show that the proposed method leads to an accurate solution with a reduced computational complexity when compared to the conventional formulation.
