The article discusses the features of designing and optimizing non-contact DC motors with fractional multi-section windings as part of an electric drive of a rotary-blade system with a gearbox. An important problem at the stage of formation of the structure of the executive electric motor of the automation system is the optimal choice of its parameters. The executive electric motor, as part of the servo adaptive system, must ensure guaranteed development of the control law, taking into account external factors of influence, which are characterized by a variable nature of the load, which requires an assessment of the operation of the machine according to the mechanical characteristics. At the same time, an important factor is that recently many manufacturers of electrical equipment have increasingly begun to turn their attention to multi-pole machines with a fractional number of slots per pole and phase, in particular those implemented by winding on a tooth, which have pronounced technological advantages. However, there remains the problem of developing approaches to the design of such machines in terms of the implementation of optimal geometric relationships. This problem is especially relevant for complex automation systems where atypical control methods are used, which requires a separate design of an electric machine for a specific task in the framework of unconditional provision of the principle of energy efficiency of the "motor-actuator" link, taking into account the adopted control system.

In the process of intelligent equipment manufacturing, AGV is an important link to realize material flow. With the increase of manufacturing scale and disturbance events, the main research direction of multi-agent systems is to realize the optimization of computing resources and the stability of control system in frequent information interaction and complex associated scenes. Therefore, in this paper, for the collaborative control of multi-agent AGV vehicle system, considering that AGV will be affected by signal interference and network packet loss during driving, as well as the dynamic time-varying characteristics of communication topology between vehicles, semi Markov process is used to describe the time-varying characteristics of communication topology, and adaptive event trigger mechanism is used to adjust the trigger threshold of the system to reduce the network burden, so as to achieve excellent control while saving network resources. Performance, In this paper, the agent model is first created. For the multi-agent object that this paper faces, the improved Q-learning algorithm is used to solve the variables in the process, and all variables are stored in the form of discrete tables. Finally, Matlab is used to simulate the product assembly process of a new energy vehicle electric drive system assembly workshop to verify the feasibility of this method. © 2025 Codon Publications.

Safe and reliable of inverter is directly related to the normal operation of permanent magnet synchronous motor drive system. Therefore, in the paper, taking a 12.5kW Permanent Magnet Synchronous Motor (PMSM) as the research object, two-dimensional transient electromagnetic field calculation model based on vector control strategy is established, and the corresponding assumptions and boundary conditions are also given. By adopting field circuit coupled calculation method, electromagnetic field is theoretically calculated under inverter normal and short circuit fault (SCF) in the upper switch of phase A, respectively. Simultaneously, due to the SCF, DC components are produced in three phase current, and the influence of the magnetic field produced by DC components on air gap magnetic field is analyzed in detail. In order to validate the accuracy of the established calculation model, some relevant experiments have been conducted. The obtained conclusion can provide theoretical basis for drive system fault diagnosis of PMSM. © 2017 IEEE.

With the development of modern technology, the intelligent household appliances are more and more popular among people. However, now the lamps on the market are mostly ordinary lamps, and they can not meet the requirements of users. Because of that situation, in this paper, an intelligent lamp based on virtual reality and face/book and voice recognition is designed. Firstly, the master control circuit and peripheral functional circuit of the intelligent lamp are designed with the key of ATMEGA2560 micro dips, and the body of the lamp is designed. At the same time, the virtual environment carrying virtual three-dimensional model is developed using Java (based on cell phone) and C++ (based on personal computer). The Open CV algorithms are used to identify images of objects that the intelligent lamp uploads. Users can interact with intelligent lamp between peripheral functional circuit and virtual environment. There are many characteristics of this intelligent lamp, such as, variety of control mode, high intelligent, stable performance, simple operation, high degree of user experience and so on. Users can modify the PC code and add related module at the reserved ports of the lamp to achieve more functions.

Dianji yu Kongzhi Xuebao/Electric Machines and control 2014年第8期18卷 87-93页

作者： Li, Dong-Jie Li, Jun-Xiang Zhang, Yue Zeng, Zhen Institute of Electromechanical Control and Automation Technology Harbin University of Science and Technology Harbin150080 China Communication Research Center Harbin Institute of Technology Harbin150080 China

For the 5DT data glove gesture recognition, the recognition method that combines the BP neural network with PSO(Particle Swarm Optimization) algorithm was proposed. Feature extraction and normalization method was adopted to establish the common gesture template. The BP neural network was trained to learn the established gesture template. Meanwhile the weights and thresholds of the BP neural network were modified by PSO algorithm. Then the trained neural network was used to recognize gestures in actual manipulation process. This method avoids the complex calibration of different operators. The advantages of BP algorithm, including simple structure, easy realization are retained, and the real-time performance and accuracy in the identification process are improved with the introduction of the PSO algorithm. The simulation and experimental results show that the proposed control method shortens the learning time efficiently and improves the real-time performance and accuracy of recognition process.

In this paper, we focus on the need for real time nanomanipulation, a 3D Master/Slave tele-nanomanipulation platform is studied with the haptic device (Omega3) as the master and the nanopositioner (Attocube) as the slave, working in scanning electron microscope (SEM). The 3D manipulation environment is developed with the help of VR technology. The platform is controlled by the enhanced virtual coupling (EVC) algorithm. The stability of the platform is discussed with Llewellyn's stability criteria. Scale factors and enhancement factor of the control system are determined, according to the force applied on master and slave terminals. Performances of the platform are tested with the ZnO nanowire manipulation experiments. Experiment results show that the platform has good performance while guaranteeing stability on ZnO nanowires manipulation in SEM using the method presented in this paper. © (2012) Trans Tech Publications, Switzerland.

This paper presents tracking control of a compliant XY nano-positioner using a transfigured loop-shaping H∞ (TLSH) control strategy, which is capable of achieving satisfied positioning performance. The employed compliant nano-positioner is featured with a symmetric 4-PP (P represents prismatic joint) structure in which four-bar flexures are designed as the prismatic joints, meanwhile two embedded piezoelectric ceramic actuators (PZT) are adopted. Based on the identified plant transfer function of the nano-positioner, the presented control strategy and the traditional PID controller are implemented with different input scanning frequencies of 0.5 Hz and 2.5 Hz for comparisons. Both the simulation results and the practical experimental results demonstrate that the presented TLSH control method obviously performs better than the traditional PID method in the presence of plant model uncertainty, which will be applied to perform practical micromanipulation tasks. © 2012 IEEE.

On-line surface roughness measurement based on specular intensity component of speckle patterns

International Conference on Information and automation (ICIA)

作者： Zhao Gao Xuezeng Zhao Department of Electromechanical Control and Automation Harbin Institute of Technology Harbin Heilongjiang China

The diffraction equations describing the wave propagation from a rough surface to an observation plane are derived. Through the statistical analysis of speckle patterns, an analytical expression relating the rms (root-mean-square) roughness to the speckle contrast is obtained. The limitations of the traditional speckle contrast method used for slightly-rough-surface roughness measurement are discussed. A specular intensity component method (SICM) is proposed as a complement to the speckle contrast method, which overcomes the disadvantages of the speckle contrast techniques. The measuring principle of the SICM is clarified in detail. An experiment is given to illustrate the whole calculation and calibration process, which shows that the SICM can be further developed for on-line measurement in the manufacturing automation industry.
