Abstract: The problems confronting multi-UAV systems when carrying out tasks are described from the perspective of architecture. According to the traits of multi-UAV systems and the needs when performing combat tasks, the functional requirements are analyzed. And a scheme of the system architecture for multi-UAV systems based on autonomous cooperation is put forward according to the thoughts of autonomous cooperative control. Meanwhile, the architecture reconstruction method of f multi-UAV system architecture under conditions of uncertainty is further studied. The design process showed that: the proposed architecture can meet the functional requirements and has good application prospects in future engineering practice.

Abstract: Loading system of pumping unit simulates the working condition of pumping unit. It can repeat all kind of the real force and motion on pumping unit and detect the quality of pumping unit. Through analyzing the indicator diagram of pumping unit, we design a elecro-hydraulic servo loading system of pumping unit which uses the method of displacement and force feedback control. Meeting the load requirement simulated it with AMESim software.

Abstract: A vehicle longitudinal dynamics model, its inverse model and a following model are established; and then two control applications namely gain scheduling Linear Quadratic (LQ) control and Model Predictive (MP) control are designed for adaptive cruise control (ACC) system; finally an integrated Simulink model including the nonlinear dynamic vehicle model and the ACC controller (either LQ or MP) was used to test the controllers in various traffic scenarios. Comparison results between the two controllers applications is provided to show the validity of the design.

Abstract: In this paper, a new bionic quadruped robot was proposed by us. The mechanism of robot we analyzed is as a hybrid series-parallel mechanism, so a new methods for constructing the kinematic model of the bionic quadruped robot very quickly and efficiently was introduced. we analyzed the workspace of the legged mechanism by using geometric composition method and numerical analysis method in the following section. Furthermore, the kinematic model of the parallel mechanism of the multi-motion mode bionic quadruped robot was constructed when the robot was in the stance phase, we also construct and solve the inverse kinematic model of the parallel mechanism of the robot, and the simulation results provide a better method for the robot’s workspace analyzing;Finally, the simulation experiment showed that the method we presented above could provide a good support for the multi-motion mode bionic quadruped robot walking smoothly and automatically.

Abstract: This article analysis the shortcomings of the current indoor lighting control and its development trend, Proposed one intelligent lighting control system based on the single chip microcomputer and combining with the light detection, pyroelectric infrared sensor. The system can intelligent adjust the lighting according to indoor light intensity, the number of people in real-time. To achieve the purpose of saving energy. Proved by the experiment, the scheme is feasible, and has certain application value.

Abstract: Aiming at the weakness of application of the traditional control method in seeding machine, a king of seeding machine used motion controller as the core was designed. The seeding machine can realize the automation of the whole seeding process, and it can automatically compensate for errors, which ensures the sowing quality. The method that uses the motion controller as the control core provides a new way of automation control for seeding machine.

Simulation results show that compared with conventional PID control, the parameter self-tuning fuzzy PID control algorithm improves the system response, shorten the adjusting time, enhances the disruptive, demonstrate the superiority of the fuzzy PID.

Abstract: For the current general heating control system tracks the set temperature hysteresis heating device to automatically adjust the real-time problem of poor design a fuzzy self-tuning proportional-integral-derivative (PID) controller parameters. Scoop out using PID control and fuzzy control algorithm combined method; fuzzy PID control parameters are adjusted. Use Matlab to model in simulink, the aryl the controller simulation analysis. The results show that the fuzzy self-tuning PID controller overshoot σ≈l%, steady-state error Island e_s=0. This method can improve the performance of the temperature control system..

Abstract: With the continuous development of milling machine, the normal milling machine was not suitable with modern processing. In order to adapt to the requirements of modern production process and quality, the electrical control system of milling machine need be improved. The electrical control system and circuit of X62W milling machine is analyzed and designed. The PLC program is compiled. All of it is proved to be reasonably and feasibly based on the experimental results.
