Navigation based on mobile devices has developed rapidly in recent years, but GPS positioning technology cannot work effectively in indoor environments, so a variety of indoor wireless positioning technologies have emerged. Due to the low power consumption, convenience and cheapness of Bluetooth Low Energy (BLE) devices, Bluetooth wireless positioning has become one of the most commonly used solutions in current indoor positioning technology. In order to solve the problem of strong fluctuation of Bluetooth signal and large positioning error in the indoor navigation process, this paper uses Kalman filter to weaken the influence of random disturbance on the real Bluetooth signal, uses maximum likelihood to estimate the position coordinates of the locator, and makes full use of multiple beacon nodes to improve positioning accuracy. In order to verify the feasibility of the indoor navigation algorithm, an indoor navigation system is designed and deployed in the field. the experimental results show that the Root Mean Square Error (RMSE) of the method proposed in this paper is 2.336 m, and the RMSE in the X and Y directions is less than 3 m, which can meet the indoor positioning and navigation needs of ordinary users. © Beijing Paike Culture Commu.

this study explores the control application of incremental PID control algorithms in an intelligent control experimental platform and verifies its feasibility. Based on the control model of the intelligent control experiment platform, we deeply analyze the impact of the digital incremental PID algorithm on the tracking and stable output waveform in the closed-loop control process. the results show that the algorithm is simple to implement, has good control effect and is less prone to oscillation.

For a centralized path planning in the multi-Agent path finding (MAPF), especially for road vehicles using traffic rules, a prioritized planning algorithm is one of the key methods that deal with real-Time problems. the time used for planning is limited, especially when a number of agents are present, and a suboptimal solution has to be found. If possible, the previous solution should be reused for the replanning. Anytime Dynamic A∗ (AD*) can both replan the path when the environment is changed dynamically and is able to return a safe, but potentially suboptimal solution in case where a maximum cycle time is exceeded. A prioritized order selection is based on the path length to the goal. To model heterogeneous traffics with vehicles and pedestrians, a combination of the bicycle and pedestrian obstacle reciprocal collision avoidance algorithms (B-ORCA and PORCA) is used to realize a naturalistic interaction among the multi-Agent system and the dynamic environment. the number of agents and of dynamic obstacles is randomly generated and the time used for planning is analyzed in view of the limited time available in the simulations. In this work, the path planning of up to three agents can be executed in real-Time in MATLAB. © 2023 the authors and IOS Press.

Minimum miscibility pressure (MMP) prediction plays an important role in design and operation of nitrogen based enhanced oil recovery processes. In this work, a comparative study of statistical and machine learning methods used for MMP estimation is carried out. these methods include weighted k-nearest neighbors, wavelet neural network, general regression neural network, extreme learning machine, regression trees (RTs), random forest, bagging RTs, boosting RTs and Gaussian process regression. Most of the predictive models developed in this study exhibited superior performance over predictive models reported in literature.

the irradiance-power curve is an important basis for examining the operating status of photovoltaic power stations. In the actual operation process, sensor failure, abnormal communication and equipment damage will bring a large number of abnormal values to the output data of photovoltaic power plants. It will have a significant impact on a variety of applications based on photovoltaic output data. this paper analyzes the typical outliers on the irradiance-power curve and proposes a photovoltaic output data cleaning method based on fuzzy clustering algorithm and quartile algorithm. By comparing with the quartile method, it is proved that this method can effectively identify abnormal data when there are a large number of outliers in the photovoltaic output data.

Aiming at the problem of low detection accuracy when the traditional method is used to detect the composite fault signal of electromechanical equipment, a method for detecting the composite fault signal of electromechanical equipment based on empirical mode decomposition is proposed. In this paper, the operation information of the electromechanical equipment is collected first, and then the complex signal is identified based on the empirical mode decomposition theory, and the location of the complex fault area of the electromechanical equipment is completed to improve the detection accuracy. Finally, experiments are used to prove the advanced nature of the proposed method. the experimental results show that the fault diagnosis accuracy of the proposed method for electromechanical equipment is higher than 75%, the response time is less than 40 ms, and the memory occupation is less than 5500 kB, all of which are superior to the traditional method and have certain application value.

Considering passenger flow will be stranded on the platform during the peak hours of urban rail transit, passenger flow congestion will be caused when the safety threshold is exceeded. A collaborative optimization model of station passenger flow control and train skip-stopping is established with the goal of minimizing the number of people exceeding the platform safety threshold and the average waiting time of passengers. A double deep Q network is used to solve it. A case study of Beijing Metro Line 13 and Changping Line is carried out with comparative analysis. In the morning peak station platform, there is a situation where the safety threshold is exceeded, and this safety problem is solved after optimization and the average waiting time of passengers is smaller than that before optimization. the case verifies the optimization effect of the model. © Beijing Paike Culture Commu.

the extraction of motor signals by traditional methods will be affected by multi-component signals and non-stationary signals, and the separation effect of motor fault signals is poor. therefore, a fast separation method of motor fault signals based on wavelet entropy is proposed. Obtain the motor fault vibration signal, convert it to the frequency domain for solution, and denoise the motor fault vibration signal through three-layer wavelet packet decomposition. Based on wavelet entropy, the sliding window is set for simulation, and the optimal features are selected for extraction to quantitatively describe the time-frequency and energy distribution of motor fault transient vibration signal. the second-order VKF filter is selected to extract multiple components at the same time, so as to realize the separation of multi-component signals. Experimental results show that this method can effectively separate and extract motor fault signals, and can achieve good results under high noise intensity.

international conference on Electrical Information and Communication Technology (EICT)

作者： Md. Ayaj Uddin Khan Md. Habibullah Dept. of Electrical and Electronic Engineering Khulna University of Engineering & Technology Khulna Bangladesh

this paper presents an empirical investigation of two current control methods for two-level inverter-fed RL loads: the conventional Finite-control-Set Predictive Current control (FCS-PCC) and a simplified FCS-PCC. the simplified PCC is considered to minimize the computational workload of the conventional PCC without sacrificing its control performance. However, the simplifying mechanism of the simplified PCC is dependent on the load parameters. Hence, an experimental analysis of the controller is required in terms of steady-state current tracking and current total harmonic distortion (thD) under load parameters variation. Experimental results show that both algorithms of PCC are load parameters dependent. Nevertheless, the simplified PCC is more sensitive to the load parameters variation than the conventional PCC.
