Current optimization methods for microgrid scheduling face issues such as insufficient precision in energy distribution, high operational costs, and inefficiency. In response to these challenges, an optimization scheduling method for multi-energy microgrids based on the QUBO (Quadratic Unconstrained Binary Optimization) quantum computing model is proposed in this paper, alongside a discretization approach based on a grid partitioning strategy. To validate the feasibility of addressing microgrid optimization scheduling problems in a quantum computing environment, a QUBO model is constructed and simulation studies are conducted in the qbsolv environment provided by D-Wave. The results indicate that operational costs are significantly reduced with an increase in the number of grids, particularly a reduction of 4.52% when the number of grids increases from five to ten. This method not only effectively enhances the precision of electricity supply and energy utilization efficiency but also reduces unnecessary electrical waste and economic costs. © Beijing Paike Culture Commu.

This paper describes a modified speed-sensorless control for induction motor (IM) based on space vector pulse width modulation and neural network. An Elman ANN method to identify the IM speed is proposed, with IM parameters employed as associated elements. The BP algorithm is used to provide an adaptive estimation of the motor speed.

Multi-UAV cooperative formation flying has significant advantages in broadening the scope of UAV operations and improving combat effectiveness. How to realize the cooperative path planning of multi-UAV is an open issue. In order to solve the search performance degradation as dimension increases, a strategy of multi-UAV cooperative path planning based on Cooperative Coevolution Particle Swarm Optimization (CCPSO) is proposed in this paper. Firstly, the initial Dubins path is generated for each UAV in the formation, of which the longest one is selected as the reference path. Intermediate waypoints are designed to modify the initial paths to avoid collisions with obstacles. Then, CCPSO algorithm is applied to optimize path parameters and adjust the path length to be equal to the reference path to ensure time coordination. Collision avoidance between UAVs is achieved in the collaborative evaluation phase. Finally, an formation rendezvous example and comparison with CCGA are given to explain the validity and excellent search ability of the proposed method. © 2019 IEEE.

Recently, delivery by quadcopter has become an increasingly popular application. Nevertheless, there are some problems and constraints. The Last Mile Problem (LMP), which involves several challenges, represents a serious problem and limitation to use the quadcopter in the delivery process. LMP which addresses several challenges is the main limitation in the delivery by quadrotor. This problem is exacerbated in densely populated cities, especially in residential complexes with multi levels buildings where there is no private and safe area for the customer to receive his parcels. To our knowledge, only partial solution has been addressed to solve this problem in literature. A new global smart box (GSB) is proposed in this paper to solve LMP. The GSBs can be networked with central controller via internet to manage them by multi simple delivery services offices distributed near from or inside trading complexes. The results got in this paper show that the GSB is reliable and solve most LMP sub problems like saving parcel, saving quadcopter, double maximum delivery distance, calculate best delivery paths, easy to perform optimal management algorithms, and decrease the cost of delivery. © 2020 IEEE.

IEEE International Symposium on Computational Intelligence in Robotics and Automation

In this paper, we propose a new approach to the high-speed wall following of wheeled mobile robots using hybrid control system. The proposed hybrid system consists of the discrete state system as the high-level process and the continuous state system as the low-level process. In discrete state system, the discrete states are defined by the user-defined constraints and the reference motion commands are specified in the abstracted motions. The reference motion commands are translated into the control inputs for each wheel in the continuous state system. The hybrid control system applied for wheeled mobile robots can combine the motion planning and autonomous navigation with obstacle avoidance in indoor navigation problem. Simulation results show that hybrid system approach is an effective method for the autonomous navigation. In the experiments of the indoor environments, we proved that the performance of the high-speed navigation is excellent.

Oscillation-controlled heat-transport tube (heat transfer coefficient in tubes in heating and cooling regions)

Heat Transfer - Asian Research 1998年第6期27卷 415-430页

In the present study, heat transfer coefficients of oscillatory flow at inner surfaces of the heating and cooling regions of oscillation-controlled heat-transport tubes (OCHTs) are investigated numerically. The numerical simulation is conducted under the following three conditions for the tube walls at the heating and cooling regions: isothermal, extremely thin, and actual wall systems. Based on the numerical results and Hausen's correlating equation for laminar flow heat transfer in tubes, a correlating equation of the heat transfer coefficient is developed which can be generally applied to these three conditions. Next, using this correlating equation and the authors' simplified model of overall thermal resistance in OCHTs, heat-transport rates are predicted, and it is found that the predicted results are in good agreement with the numerical results. Finally, numerical simulation is conducted also to compare the heat-transport rates of OCHTs with those of the conventional forced circulation type under the same pumping power. The results indicate that there exist oscillatory flow regions in which the heat-transport rate of the phase-shifted OCHTs is larger than that of the conventional circulation type.

In a measurement system, new representation methods are necessary to maintain the uncertainty and to supply more powerful ability for reasoning and transformation between numerical system and symbolic system. A grey measurement system is discussed from the point of view of intelligent sensors and incomplete information processing compared with a numerical and symbolized measurement system. The methods of grey representation and information processing are proposed for data collection and reasoning. As a case study, multi-ultrasonic sensor systems are demonstrated to verify the effectiveness of the proposed methods.

Three-dimensional dynamic modeling and numerical simulation of manipulating deformable linear objects (DLOs) such as hoses, wire and cables are studied in this paper. Several coordinate systems are introduced first to describe the deformation of DLOs. The dynamic three-dimensional deformation of an inextensible linear object is formulated using finite element method (FEM) and lagrange motion equations. The proposed method provides more efficient simulation of dynamic manipulating DLOs with faster computation speed. Two simulation examples are illustrated to confirm the effectiveness of our methods. One is a comparison simulation study and the other shows the three-dimensional dynamic character of the DLO. © 2011 Chinese Assoc of Automati.

The public security has become an important issue in recent years, especially, the safe manipulation and control of vehicles in preventing the growing number of traffic accident fatalities. Accidents caused by drivers' drowsiness have a high fatality rate due to the decline of drivers' abilities in perception, recognition, and vehicle control abilities while sleepy. Preventing such an accident requires a technique for detecting, estimating, and predicting the level of alertness of a driver and a mechanism to maintain the driver's maximum performance of driving. The ICAFNN is a fuzzy neural network (FNN) capable of parameter self-adapting and structure self-constructing to acquire a small number of fuzzy rules for interpreting the embedded knowledge of a system from the given training data set. Our experiments show that the ICAFNN can achieve significant improvements in the accuracy of drowsiness estimation compared with our previous works.
