This paper proposes a Kalman filter based state-of-charge (SOC) estimation matlab function using a second-order RC equivalent circuit model (ECM). The function requires the SOC-OCV (open circuit voltage) curve, internal resistance, and second-order RC ECM battery parameters. Users have an option to use an extended Kalman filter (EKF) or adaptive extended Kalman filter (AEKF) algorithms as well as temperature dependent battery data. An example of the function is illustrated using the LA92 driving cycle of a Turnigy battery performed at multiple temperature ranging from -10 degrees C to 40 degrees C.

TopoZeko is a matlab function for plotting a variety of natural environments with a pronounced topography, such as glaciers, volcanoes and lakes in mountainous regions. This function extends existing matlab plotting routines and allows for high-quality 3-D landscape visualization, with a single color defining a featured surface type or with a color scale defining the magnitude of a variable. As an input, only the elevation of the subsurface (typically the bedrock) and the surface are needed, which can be complemented by various input parameters. Several visualization examples are provided alongside with animations, which can directly be generated in the code. Additionally a simple function to calculate the position of the sun is introduced, which can be used to visualize the daily insolation/shadow cycle over a landscape. (C) 2017 The Author.

In this study, modeling and simulation of a speed sensored field-oriented control (FOC) of a permanent magnet synchronous motor (PMSM) drive is developed by using matlab function blocks in matlab/Simulink. This method allows easier algorithm and software development stages for experimental studies compared to the classical block diagram approach. The superiority of the method over commonly used "Code Generation" tools is also emphasized. First, a matlab/Simulink model of the FOC of PMSM drive is developed by using matlab programming in matlab functions similar to C coding techniques. The results of the simulation are presented. Then, the matlab programming based codes developed in simulation are implemented in a TMS320F28335 floating-point MCU by using C programming language and the experimental results are obtained. Finally, the results of the simulation and experiments are compared.

Watering is a traditional practice of watering plants. Still, it is ineffective because it leads to an agricultural crop with limited returns due to inappropriate irrigation processes. IoT-based Automation irrigation was used to overcome this problem, improving farm production and rationalising the amount of water. This paper presents an automatic plant watering system using matlab/Simulink implementation and IoT technologies. The system collects real-time data and regulates irrigation through an on-off control strategy. This system is processed using an embedded card, sensors, and matlab/Simulink environment. Also, a mobile application is used for monitoring purposes. The system is modelled in matlab/Simulink using the matlab function and the map equation to enhance performance. Although this experiment took place during a mildly turbulent winter, the results showed the effectiveness of the project in improving the efficiency of distribution and providing water in an appropriate quantity and time

Digraph-building method for finding a set of minimal realizations of 2-D dynamic systems

BULLETIN OF THE POLISH ACADEMY OF SCIENCES-TECHNICAL SCIENCES 2018年第5期66卷 589-597页

This paper presents a digraph-building method designed to find the determination of realization of two-dimensional dynamic system. The main differences between the method proposed and other state-of-the-art solutions used include finding a set of realizations (belonging to a defined class) instead of only one realization, and the fact that obtained realizations have minimal size of state matrices. In the article, the proposed method is described, compared to state-of-the-art methods and illustrated with numerical examples. To the best of authors' knowledge, the method shown in the paper is superior to all other state-of-the-art solutions both in terms of number of solutions and their matrix size. Additionally, matlab function for determination of realization based on the set of state matrices is included.

Modeling of ECG signal is of much importance as the outcome of it is needed for compression of ECG waveform for remote transmission by wireless link, reconstruction of both normal and abnormal ECG waveform without patient, studying the performance of cardiovascular system or heart. The present work proposes a novel method to design a model of heart according to functions of electrical activity of major parts inside heart. Each individual major part generates potential wave w.r.t. time of its own nature due to depolarization and repolarization processes. The individual potential waves have been modeled using Fourier analysis method. In this paper modeling P-R interval wave, QRS interval wave, S-T interval wave and ECG wave for one cycle using matlab Simulink. The proper utilization of matlab functions (PR Segment block, QRS Segment block, ST Segment block), matlab curve fit GUI=TOOLBOX and matlab Simulink tool can lead us to work with ECG signals for processing. The simulink model major parts have been realized by interval generator blocks, ramp function blocks, product blocks, segment generation blocks and adder thereby generating P-R interval wave, QRS interval wave and S-T interval wave within different time ranges of one cycle of ECG wave. The individuals waves as obtained from PR segment block, QRS segment block, ST segment block are synthesized to produce a typical composite ECG wave.

Open and Closed Logarithmic Nyquist Plots 13

Open and Closed Logarithmic Nyquist Plots

13th European Control Conference (ECC)

The Nyquist plot is a fundamental tool in the investigation of the stability of control systems. Usually Nyquist polar diagrams are plotted in a linear scale and often, in particular when poles at the origin are present, the diagrams need different levels of magnification in order to inspect the behavior of the frequency response in the areas very close to or very far from the origin of the complex plane. In this paper a new logarithmic Nyquist plot is proposed where the amplitude is in a logarithmic scale and the diagram is entirely contained and shown in a circle of finite radius. This method does not need to zoom in or zoom out the plot. All the considerations made by Nyquist stability criterion can be done with this plot which maintains all the properties of polar plots such as gain and phase margins, intersection points with the real axis, encirclements of the critical point. The design of first order lead and lag compensators can be done on this diagram in a simple way. The proposed new Nyquist plot is implemented in a matlab function available to users.

COMPUTING BOUNDS FOR THE MIXED-MU-PROBLEM

引用

INTERNATIONAL JOURNAL OF ROBUST AND NONLINEAR CONTROL 1995年第6期5卷 573-590页

作者： YOUNG, PM NEWLIN, MP DOYLE, JC CALTECH PASADENA CA 91125 USA

Robustness problems involving real parametric uncertainty can be reformulated as mixed mu problems, where the block-structured uncertainty description is allowed to contain both real and complex blocks. Upper and lower bounds for the mixed mu problem have recently been developed, and this paper examines the computational aspects of these bounds, In particular a practical algorithm is developed to compute the bounds. This has been implemented as a matlab function (m-fiie), which is currently available in conjunction with the mu-Tools toolbox. Some results from our extensive numerical experience with the algorithm are presented. The algorithm performance is very encouraging, in terms both of accuracy of the resulting bounds, and of growth rate in required computation with problem size. In particular it appears that one can handle medium-size problems (fewer than 100 perturbations) with reasonable computational requirements.
