Based on state tree structures, supervisory control of preventing electric misoperation system is developed. A preventing electric misoperation system is an important part of substation. It guarantees that each operation of primary equipment in a substation is safety and reliable. The operating targets of preventing electric misoperation system are circuit breaker, switch and ground switch, which are discrete-event dynamic components that are event-driven and have discrete event behavior. Owing to the inherent discrete switching nature, in this paper we model the plant and specification as state tree structures. By using the STSLib software, the control logic (supervisor) is synthesized. In this paper we illustrate the detailed procedure of this approach and verify that the synthesized control logic (supervisor) is feasible.

According to the theory of cylinder indexing cam mechanism, based on the modular design, the CAD/CAM system of cylinder indexing cam mechanism is developed by VB6.0 and Creo3.0. This system is a visual interface which is build by VB6.0and it can be used to output the three-dimensional coordinate data and processing date of the cylinder indexing cam through the basic parameters input of cam and the choosing of motion law for cam follower. Then this system can save the date file as the format of”.ibl". After that, the file is imported into Creo3.0 to generate curve and surface. At last, the solid model of the cam is obtained by merging the surface and removing the theoretical profile surface. The practicability and convenience of the system are verified and the design and machining efficiency of the cylindrical indexing cam are greatly improved.

The vehicular inverted pendulum (VIP) system is one of the most important issues in dynamics and control theory, and has been widely used as a benchmark for testing control algorithms. However, the tracking control and swing-up control of the VIP system have often been investigated separately. In this paper, by combining the Zhang dynamics (ZD) method and the traditional gradient dynamics (GD) method, two Zhang-gradient (ZG) controllers of z2g0 type and z2g1 type are constructed. Note that z2g1 controller can conquer the singularity problem encountered by z2g0 controller and other conventional controllers, thus achieving the tracking control and swing-up control of VIP system simultaneously. The numerical-experimental results substantiate the feasibility and effectiveness of z2g0 and z2g1 controllers for tracking control of the VIP system. Particularly, numerical-experimental results illustrate that the z2g1 controller can achieve tracking control and swing-up control simultaneously with suitable control input. Thus, the z2g1 controller is more suitable for handling the VIP system with nonzero link mass.

With the development of the aviation industry and the improvement of people's living standard, more and more people choose aircraft as their way of travel, but the airline adjusts the price according to the revenue management in real time. The purpose of this paper is to design different decision-making tools from the customer's perspective, and to provide customers with the relevant information needed to determine when to purchase a ticket properly. This paper models data using random forest algorithm and builds decision-making tools, taking into account the price fluctuation and amplitude of fluctuation, and suggests the customers when to buy their tickets and when to postpone the purchase. As an application, the paper analyzes air prices for routes from PEK to HET, CAN, SHA, DLC and CSX over the course of two months, and takes into account advance-purchase ticket sales of up to 40 days. By comparing and analyzing the forecasting performances of each model, the experimental results show that random forest model is more reliable in the condition of adding new features. Our study suggests that the model can serve as a basis for customers to make purchase decisions, so as to achieve the purpose of saving money for customers.

In order to solve the singularity problem of the Jacobian matrix in the robotic inverse kinematics method, a new singular processing algorithm is proposed. Based on the damped least-square (DLS) method, the damping coefficients, by using the singular value decomposition (SVD) of the Jacobian matrix, are optimized from the fixed value of the traditional algorithm to the dynamic value adjusted with the Jacobian matrix. It is ensured that the angular velocity curve of each joint is continuous and smooth when the robot passes through the singularity, and the robustness of the inverse solution algorithm is enhanced. The algorithm is simulated on the Kawasaki BA006N robot, results show that the robot does not introduce the tracking error at the non-singular position. At the singular position, the joint motion of the robot is smooth and the singular robustness is better than that of the existing algorithm.

General queueing modeling method, Stochastic Timed Automation, is employed to model the Semiconductor Wafer Fabrication System because of its flexibility and fidelity. The machine allocation is formulated as a stochastic integer programming problem with the objective to optimize the throughput of the Semiconductor Wafer Fabrication System. And we propose an Optimal Computing Budget Allocation-based Stochastic Greedy Search algorithm to dynamically allocate machines, each time we allocate only one machine into the best performed station until all the machines are allocated into the Semiconductor Wafer Fabrication System. Numerical examples suggest our method is efficient to find a good allocation solution.

A multi-standard analog front-end architecture SoC (System on Chip) for 13.56MHz radio frequency is proposed. It consists of a transmitter and a receiver. The transmitter adjusts its ASK modulation index with a digitally controlled mode select register, thus supporting RFID standards of ISO/IEC 14443 Type A/B. In the receiver, an envelope detector, a variable gain amplifier and a shaping circuit are introduced. The envelope detector based on operational amplifier can even detector signals with a magnitude of only 100mV. Different gain and compare voltage can be achieved through the variable gain amplifier and shaping circuit which controlled by registers. The proposed analog front-end is implemented in SMIC 0.18um CMOS process at 1.8V single supply. The simulation results indicate the analog front-end satisfies the ISO/IEC 14443 Type A/B standards. The proposed circuit is suitable for RFID reader and NFC transceiver.

A high-degree low-pedestal pulse compression scheme is presented. The scheme is a three-step compression configuration. It employs an anomalously dispersive single-mode fiber (SMF) as the first compression stage. At the second stage, another anomalously dispersive SMF is used for further compression. After the first two stages of compression, the compressed pulses usually suffer from undesired pedestal generation due to soliton-effect compression. At the final stage, a nonlinear optical loop mirror (NOLM) is adopted for simultaneous compression and pedestal reduction. The numerical results show that the pulse can be effectively compressed through cascaded compression and its pedestal can be efficiently suppressed by the NOLM. The three-stage pulse compression with a NOLM can improve the compressed pulse quality compared to that without a NOLM. The proposed pulse compression method can achieve high-degree low-pedestal pulse compression and provides a feasible and a much simpler design in practice.

That process has associated with the affection due to addition quality produced by wake capture. With introducing rotate circulation. This paper has calculated the lift, drag force, and pitch torque which take part on the wings' surfaces. Ignoring the wings' quality, the aircraft could be viewed as a rigid body. According to the Newton-Euler principle, establishing the dynamics model of aircraft is realized. And then, this paper has accomplished the indirect Adaptive controller and the update rate law. The algorithm could give dynamic compensation on uncertainty of the system. At last, this paper has taken the simulation of the algorithm. The result of that has verified the effectiveness of the controller design.

Multi-degree of freedom manipulators have become a hotspot in the field of robotics because of many advantages. In this paper, a 5-DOF manipulator was taken as the object of study. The modal analysis on it was carried out by methods of test and finite element analysis. A model updating method based on sensitivity analysis was put forward, and the final finite element model was established by iterative optimization. By means of correlation analysis and MAC modal judgment criterion, it was verified that the simulation results of the final simulation model of the manipulator have a good correlation with the experimental modal results. The finite element model determined by this method accurately reflected the actual structural dynamic characteristics of the manipulator.
