There are several drawbacks to the traditional proportional-integral (PI) control of permanent magnet synchronous motors (PMSM), including its poor flexibility and heightened sensitivity to outside disturbances. To solve these problems, this paper uses a fuzzy PI controllers to augment the PMSM vector control model. Firstly, based on the mathematical model, the corresponding PI controller is established; on this basis, the fuzzy rules are used to adjust the parameters of the PI controller in real time for the defect that the parameters of the PI controller cannot be automatically adjusted in real time operation of the motor, which leads to poor dynamic characteristics. When compared to regular PI controllers, these fuzzy PI controllers improve the system’s anti-disturbance performance and control precision.

A monitoring system of LED upholstery lights based on TCP/IP and DMX512 is a common feature. The objective of the paper is to describe a hardware circuit design of the device, and its main software process. The issue here is that lighting system of the LED street light is optimized from the perspectives of the light source of the street light, the control circuit, the optimal tilt angle of the battery components, and the volume size of the battery components and batteries. The review of the existing literature and systems is used as a methodology for the studies. The LED light can be turned on and off and the brightness can be adjusted according to the surrounding environmental conditions. The device can achieve wide dimming range, high power output, and good signal transmission performance. As a result, while ensuring smooth and reliable operation of the system, it reduces the size and cost of the system as much as possible.

computervision and Image processing are some of the most important technical aspects in the domain of object detection and reconstruction. These concepts provide solutions not only restricted to the engineering domain but also across the various domains. In this article, the proposed framework mainly deals with the scenario of the generation of face masks in 3D view with the aid of selfie images using computervision and image processing methodologies. The proposed framework consists of two kinds of algorithms that generate face mak with the aid of single and multiple images respectively. Those adaptive algorithms are discussed along with their implementation. The adaptive algorithm utilized for multiple image input names as MIIO3D and the adaptive algorithm for single image input named as SIIO3D implementation for the construction of an efficient 3D face mask. The input images considered are from real-time aspects. Data visualization and their comparisons made with the aid of Tableau.

A modern, inventive, and natural method of nonverbal communication is offered by a hand gesture recognition system. It can be used in many different contexts, including sign language and human-computer interaction. This implementation's objective is to discuss a novel method of hands gestures recognition based on the identification of certain shape-based elements. A single camera is used to record the user's gesture and feed it into the system. The development of a system that can recognise certain human gestures and use them to transfer data for device control is one of the main goals of gesture recognition. Real-time gesture recognition enables users to controlcomputers by making certain gestures in front of a video monitor. The development of a system that can recognise certain human gestures and use them to communicate data for device control is one of the main objectives of gesture recognition A user can operate a computer by making a certain gesture in front of a video camera that is attached to it by implementing real-time gesture recognition. In this project, we'll build a hand gesture volume control system with the help of the OpenCV module. Here you can use hand gestures to operate the system without a keyboard or mouse.

In this paper, design and implementation of a 2D graphics processing hardware unit using FPGA for educational purpose is presented. We propose a more simple & minimalist GPU architecture, which is flexible and easy to understand than existing industrial GPUs. We present a platform for understanding GPU architecture by implementing of graphics algorithms on FPGA for students to use this in laboratories. Students can be benefited from this work as it can be used as a base understanding tool in terms of GPU architecture. It can also be extended to be used in cross disciplinary applications like 3D rendering, computervision and signal processing visualisation. This research includes descriptions of hardware realization of 2D rasterization rendering algorithms. Hardware Description Language (HDL) called verilog is utilized in designing the architecture. Xilinx Vivado Design Suite software is used for FPGA implementation, targeting Artix 7 FPGA board, which allows users to comprehend the fundamental ideas of hardware design and their applications in graphics rendering.

Existing researchs on multi-robots task assignment focus on improving the task assignment efficiency without considering the task execution time and ignoring the overall task completion efficiency, which leads to its low computational efficiency in dynamic task assignment scenarios. In addition, the use of a centralized control structure requires high communication quality between robots. To address the above issues, we propose a distributed task assignment method for multiple robots based on dynamic auction rules. The method uses distributed control of robot swarms to share and dynamically update each other's task sets, employs dynamic auction rules for task bidding, adds links to adjust the task execution order, and considers the overall task completion efficiency. Finally, relevant experiments are designed, and the experimental results show that the algorithm is more efficient in terms of distribution and stability, balancing higher execution efficiency and lower motion cost.

With the rapid development of computer networks, people's use of the Internet has become more and more common, and network security issues are becoming increasingly serious. Compared with intrusion detection, the development of intrusion response is slightly lagging behind. There are many devices for intrusion detection, alarm information is difficult to analyze and there are false alarms and isolated alarms, and many detection strategies require manual operation, which greatly increases the time cost and labor cost of intrusion response. In this paper, we propose an intrusion response method based on Bayesian attack graph, which effectively uses the alarm information and adopts the attack behavior prediction algorithm of Bayesian attack graph to block the attack path of network attacks for the uncertainty of attack events and enhance system security.
