This paper presents a direct AC-AC converter for an electronic power transformer based on the energy injection control. It achieves single-stage energy transformation. A simple and special direct AC-AC converter is used instead of a matrix converter with a complex control method and many switches. This paper analyzes its work models and operation principle in energy injection mode and free oscillation mode. A simulation is carried out to prove that the direct AC-AC converter work in soft switch state all the time, and the output current is unchanged when the load is changing. The simulation also verifies that this special electronic power transformer can achieve power single transformation and energy bidirectional flow, which is beneficial to improve energy utilization efficiency.

In this paper, PID controllers are designed to enhance the trajectory tracking performance of a flexible link robot. Firstly, a PI controller is used where conventional Ziegler-Nichols method adjusts the controller parameters. In addition, Fuzzy PID controller is designed in which fuzzy rules are utilized on-line to tune the PID controller parameters based on the current value of error and its first time-derivative. Also, effects of several defuzzification methods on the closed-loop system are investigated in this paper. A flexible link robot is implemented and controllers are applied. Experimental results confirm the performance of the fuzzy PID controller.

During the past decade, Electro-Hydraulic system has performed a significant role in industrial engineering as an actuator for high performance and precision positioning applications. In this case, many control methods have been developed for an electro-hydraulic actuated clutch. In this paper a Linear Quadratic Regulators (LQR) is proposed to trajectory control of a wet clutch actuated by a hydraulic servo valve mechanism. Simulation study was performed using linearized mathematical model of the system implemented in MATLAB software. Based on the simulation results performance of the proposed controller was evaluated and discussed.

Least square support vector machine is an excellent algorithm which can be used to model and classify. If appropriate mapping functions and parameters are selected, the result should be better. An improved particle swarm optimization with changeable inertia parameter and velocity weight is present and then it is used to search better parameter to optimize support vector machine which are used to diagnose faults existed in coal powder producing process. Simulation results show that the improved PSO has higher search precision and global search ability and the faults diagnosis algorithm coupled PSO and LS-SVM has higher diagnosis accuracy rate. This diagnosis is reasonable and applicable.

Strawberries possess impressive nutritional and medicinal value, and the demand for them has been kept on increasing on the global market. For their harvest consumes a large portion of the whole production costs and causes health problems to the labors, researching and developing strawberry harvesting robots is becoming an emergency of meeting the economy requirement in the world. In consideration of the parallel mechanisms' advantages and the lack of their utilization in the field of strawberry harvest, this paper proposed a 4-PPPR manipulator to pick strawberries in the ridge culture. Based on the GF set theory, this manipulator was proved to have three translational motion DOF and one rotation DOF, which make it competent to conduct harvest task in the ridge cultivation model. Furthermore, analyses for inverse kinematics and velocity equation were also carried out in order to support further studies, such as controlling and optimizing of this manipulator.

The path planning method using intelligence optimization algorithm cannot meet the unmanned aerial vehicle (UAV) mobility constraints because of its spatial grid division. Besides, the path smoothing method of interpolation after path planning increases the amount and complexity of algorithm. Considering to solve UAV path planning smoothing problem in the process of scenario modelling, this paper proposed an adaptive grid model, which provide the sparsest grid division under the UAV mobility constraints. The simulation results implicate that the path using proposed model satisfies mobility constraints and decreases the computational complexity effectively in both 2-D and 3-D path planning.

In this paper, we consider the problem of designing state observers for a class of one-sided Lipschitz time-delay systems subject to disturbances. Not only the plants but also the outputs of the systems are subject to time delays and disturbances. The one-sided Lipschitz and quadratically inner-bounded conditions, which are more general than the traditional Lipschitz condition, are utilized to cover a broader class of nonlinearities. Based on the Lyapunov-Krasovskii approach, a robust observer design is proposed where synthesis condition is derived in terms of linear matrix inequality (LMI). A numerical example is given to show the effectiveness of the obtained results.
