This paper presents a particle swarm optimization (PSO) timing scheme for a single intersection and a bidirectional green wave coordination control scheme for an artery. The timing strategy is proposed to reduce vehicle delays based on Akcelik delay model at the intersection via adaptive particle swarm optimization (APSO) algorithm. The coordination control scheme is designed to make as many vehicles...
Parallelization is the main method to improve efficiency for solving sparse linear equations. This paper summarized the computing dependency relations of power system off/on line analysis application types. Almost all kinds of numerical methods related to power system computation can be attributed to solving Ax =b (A is sparse), and the direct method based on the Gaussian elimination is used widely,...
The amorphous alloy transformer has less no-load current and loss, but the structure characteristics of the runway shape winding make it show greater vibration intensity and noise at the load condition. Based on the structure characteristics of the amorphous alloy transformer with runway shape winding, a leakage-stress-acoustic coupled calculation model is proposed to calculate the electromagnetic...
To deal with parametric uncertainty, load disturbance together with other nonlinear factors in highspeed permanent magnet synchronous motor (PMSM) systems, an adaptive robust controller (ARC) is proposed based on direct torque control method. In the high-speed PMSM modeling process, the unknown nonlinear factors, including modeling error and uncertain disturbance, are considered. Based on the optimized...
Lithium Ion batteries usually degrade to an unacceptable capacity level after hundreds or even thousands of cycles. The continuously observed capacity fade data over time and their internal structure can be informative for constructing capacity fade models. This paper applies a mean-covariance decomposition modeling method to analyze the capacity fade data. The proposed approach directly examines...
Due to the limitations of the size of the wireless capsule robot using in diagnosis and treatment of gastrointestinal diseases, various functional modules cannot be integrated into a single capsule robot, which caused the practicality of the robot being reduced. This paper proposed the wireless spiral capsule robot with modular structure driven by the external magnetic field which have the mechanism...
Cerebrovascular disease is a serious threat to people's health. Because of its small trauma, quick recovery and good effect, vascular interventional surgery is widely used. Through the use of VR (virtual reality) technology of vascular interventional surgery doctor training system, people can perform surgery simulation, which can improve the doctor's ability to operate surgery. Aiming at path planning...
In this paper, a control system of upper limb rehabilitation robot based on LabVIEW was proposed, and the structure of the control system was also provided. Through using the LabVIEW, the system had a good software interface and control effect. In addition, with the communication protocol between the robot and LabVIEW, the system can realize the real-time transmission of control signal and control...
The traditional underwater robot has some limitations when conducting survey in underwater space. These limitations also reflect in some aspects, such as micro-structure, movement patterns, positional accuracy and endurance time. In order to overcome these shortages, a shape memory alloys (SMAs) actuator-based Salps-inspired son robot is designed and developed, which is connected with an amphibious...
In this paper, to deal with the performance of the medical microrobot in fluid condition, we proposed a novel type of magnetically actuated hybrid microrobot. The magnetically actuated hybrid microrobot has characteristics of controllability and multi-function. It has a simple structure, a simple control strategy with a rotational magnetic field and good dynamic in fluid. The magnetically actuated...
In order to solve the problem that the capsule endoscope is limited by energy, it can reduce the volume and weight of the capsule robot by using the external wireless power to replace the button cell. This paper proposed a miniaturized, low-power energy transmission mode based on magnetic coupling resonant WPT(Wireless Power Transmission). Based on the scheme design, we finished the contrasting experiments...
In recent years, application of biomechanical modeling techniques in the area of medical image analysis and surgical simulation is a commonly method. In the development of medical surgery robot technology, haptic and virtual reality systems also have attended consideration on simulators as a tool of medical training. In order to enhance the authenticity of our vascular interventional surgery and improve...
In recent years, minimally invasive interventional surgery with catheter as the important surgical instrument has been widely applied in the treatment of Cardio-Cerebrovascular disease for its small tranma, fast recovery and other many advantages in the world. But traditional intervention operation of cardiovascular disease still has many insufficient sections. the tools of operation have a poor operability,...
Exoskeleton upper limb rehabilitation robots are more and more applied to help hemiplegic patients to implement rehabilitation training, which makes up the shortage of rehabilitation only depend on doctors. Aiming at the training of patients' hand exercise, in this paper a kind of human-computer interaction of exoskeleton hand rehabilitation robots based on LabVIEW system was proposed, which was mainly...
IEEE 802.16m, aiming at providing secure communication pathways between the base station (BS) and the mobile station (MS), is a broadband wireless MAN (Metropolitan Area Network) standard. Its security sublayer contains a Privacy Key Management (PKM) protocol, which achieves authentication and key management in the communication process. In this paper, we apply Communicating Sequential Processes (CSP)...
Since one navigation satellite can only be equipped with limited number of ISLs, the navigation satellite network forms a typical space delay/disruption tolerant network (DTN) which poses significant challenges to the design of transport protocol. Generally, the transport protocols can be divided into two categories which are end-to-end and hop-by-hop. The Transmission Control Protocol (TCP) employed...
Under the action of a strong earthquake, pier aqueduct structure is prone to injuries in the pier damage, making the whole structural seismic performance significantly reduced. Based on the concrete plastic damage constitutive model, a large gravity pier aqueduct structure is analyzed in the law of dynamic response under the action of earthquake. Compared with linear structure, the aseismic characteristics...
How to operate a BFG/coal co-firing boiler in high efficiency is challenging for a gas/solid multi-fuel combustion system. Taking operation data from a real boiler, this study proposes an operation optimization strategy of BFG/coal co-firing boiler based on deep learning.

In this paper, a robust fuzzy-tuned PID controller is proposed for the trajectory tracking and vibration control of a flexible joint manipulator system (FJMS) with parametric uncertainties. Flexible joint manipulators are widely used in industry due to their flexibility, light in weight and fast response, low cost, and low energy consumption. The dynamic modeling via Euler-Lagrange equation for a...
Fault isolation is an essential step in multivariate statistical process monitoring, which discovers the cause of the detected fault. The common adopted techniques for fault isolation, such as contribution plots, reconstruction analysis, branch and bound, etc., often suffer from the problems of the smearing effect, insufficient historical fault data, and heavy computational burden. In this paper,...
