This article deals with the operations control of factory with alternative sources used to reduce its own power supply. The basic conditions of this operation (factory operation conditions and algorithm conditions of controllers) are formulated. Two equivalent circuits with mathematical models were created. Created models are intended for use in control programs to calculate and predict all possible operating conditions and select the most appropriate state. First model is based on currents and second model is based on power for describing factory operations. Example of simulation of created control algorithm using matlab is shown.

In this paper, the structure and the dynamic characteristics of quadrotor UAV are analyzed and studied in detail where the dynamic model of quadrotor UAV is established. The dynamic model is used to describe the flight attitude of quadrotor UAV, and the modeling of quadrotor UAV is carried out on the basis of the above mentioned information. Dynamic modeling is a simulation model established by the flight principle of the aircraft with the force relationship under various motion states such as referring to Newton Euler model. After the model is built, the simulation is carried out in matlab / Simulink software to prove the merit of the method used.

In this paper, the need to develop an advanced and efficient propulsion system, to support missions demanding increased endurance of Unmanned Underwater Vehicles is investigated, and a conceptual model is proposed by varying several operational and design parameters. Electric propulsion system (EPS), in which battery is the power source, electric motor is the fundamental driving element and propellers are the core driven equipment, is a very important concept for an energy efficient propulsion of underwater vehicles. The basic mathematical design of proposed EPS accumulates the vital abilities to be less noisy and more energy efficient, provide high initial torque along with high speed and enough endurance to acquire the desired target range. The simulations using matlab have been carried out to produce graphs between drag and multiple operational and design variables. The out-turns of this paper are typically based upon the simulations and analytical aftermaths. The suggested model of propulsion system bestows a clear understanding that the basal operational parameters such as speed and depth of the underwater vehicles are related directly with the drag whereas the fundamental design specifications such as shape, surface area and weight of the submersible vehicles also possess, physically, a direct relation with the drag force.

High voltage transmission is a complex process, because partial discharge and various problems of lines will produce current response of different frequency, so it needs vector synthesis in different time and space. In this paper, based on the theory of vector synthesis, through the SIMULINK module of matlab software voltage is simulated, we obtain the coupling graph and vector synthesis graph of different voltage. From the curve we can see that before vector synthesis, the voltage has different frequencies and the peak output values, after vector synthesis, the voltage has stable frequency and peak output values, with good transmission effect. It provides the theoretical reference for the research on high voltage power system.

Organic transistor plays an important role in electronic applications as it provides additional benefit of flexibility and low cost compared to silicon electronic devices. simulation and analytical model of such organic devices helps in improving and optimizing the performance of the device. There are various parameters that effect the performance of the device. In this work, analytical simulation of the organic device is performed based on the device physics to simulate the output characteristics using matlab for various channel length (L). Here, the impact on channel length is observed on varying the device length and its impact is observed on the drain current. Different channel length taken into consideration and the simulation result shows that the drain current increases when the channel length decreased. Thus, simulation of such analytical models helps in extracting the useful information about the performance of the organic transistors.

Dynamic simulation and optimization of anaerobic digestion processes using matlab

Time series-based modeling provides a fundamental understanding of process fluctuations in an anaerobic digestion process. However, such models are scarce in literature. In this work, a dynamic model was developed based on modified Hill's model using matlab, which can predict biomethane production with time series. This model can predict the biomethane production for both batch and continuous process, across substrates and at diverse conditions such as total solids, loading rate, and days of operation. The deviation between literature and the developed model was less than +/- 7.6%, which shows the accuracy and robustness of this model. Moreover, statistical analysis showed there was no significant difference between literature and simulation, verifying the null hypothesis. Finding a steady and optimized loading rate was necessary to an industrial perspective, which usually requires extensive experimental data. With the developed model, a stable and optimal methane yield generating loading rate could be identified at minimal input.

Research on Torque Compensation Strategy of Wind Maneuver Model Experimental System by Increasing the Analog Multiple of Moment of Inertia

ENERGIES 2025年第1期18卷

作者： Sun, Qiming Qiu, Yaqin Zhang, Chao Nanjing Forestry Univ Coll Informat Sci & Technol Nanjing 210037 Peoples R China Henan Inst Technol Sch Intelligent Engn Xinxiang 453003 Peoples R China Krirk Univ Int Coll Bangkok 10220 Thailand

Fan power generation, a form of new energy, has gained significant attention. However, as fan capacities grow, the challenges in the development process also increase. A wind maneuver model experiment system must be constructed to simulate the actual fan operation dynamics. The wind turbine simulator is essential for conducting experiments on wind turbines and advancing the research of wind power production technology. However, due to the insufficient moment of inertia in wind turbine simulators under laboratory conditions, physical compensation methods are challenging to implement. Therefore, most scholars rely on software compensation algorithms to realize the stability simulation of wind turbine simulators with small moments of inertia and actual wind turbines with large moments of inertia. Under this research background, this paper presents the existing moment of inertia compensation strategies based on current research hotspots. The theoretical foundation covers the mechanical dynamic models of both actual wind turbines and simulators along with an analysis of inertia compensation strategies, including high-order filters and feedforward bias suppression. Finally, the Simulink simulation platform is used to compare and validate the effectiveness of these strategies.
