Abstract: Motor plays an important role in industrial areas. It is necessary to get the motor parameters and performance indicators by a series of experiments before they are used. For motor test hardware platform, a software based on LabVIEW is designed. It has an easy-operating interface and makes an experiment easy and automatic. Experimental results show that the software has good practicality.

Abstract: As major areas in the world have been protected with surveillance information with the development of wireless communication technologies, underground mines are still hit by frequent accidents due to insufficient monitoring and sensing, which would be improved with implementation of Internet of Things (IOT). However, a low-power, high reliability wireless communication equipment integrated with personnel localization, underground gas monitoring and IOT functions has not been implemented to enable underground IOT. Having explored wireless technologies and underground communication technologies, we propose in the paper the design of a communication system incorporating wireless call, gas monitoring, personnel localization functions through the integration of ZigBee (IEEE802.15.4) and Ethernet. This system has been realized and tested under laboratory conditions. The system was accepted by China coal mines in principle for application in their coal mine production line.

Abstract: For a novel electric clutch actuator, a nonlinear feedforward-feedback control scheme is proposed to improve the performance of the position tracking control. The feedforward control is designed based on flatness in consideration of the system nonlinearities, and the linear feedback control is given to accommodate the model errors and the disturbances. Lookup tables, which are used to represent nonlinear characteristics of the actuator systems, such as friction force, appear in their original form in the designed feedforward controller. The designed controller is evaluated through simulations and experimental tests, which show that the proposed controller satisfied the control requirement. Comparison with PID control is given as well.

Abstract: In the steam generator with water level control system of nuclear power plant, there are various uncertainties in the controlled devices. Any actual system had certain nonlinear. Because of the steam generator is very important equipment in nuclear power plants, water level control plays a decisive role for the safe operation of nuclear power plant and it required stable operation and fast response of the whole system. For the highly complex, non-linear system , the traditional cascade PID control had been used cannot obtain satisfactory control effect, this paper try to use RBF neural network to optimize the PID parameters. The simulation experiments show that: the rbf neural network optimized controller made the control system’s robustness and control quality superior than the traditional PID controller, and described the method can be applied more widely.

Abstract: Underground communication system can be organized as a delay tolerant network (DTN), where delay analysis is of importance. In this paper, we derive the analysis method of block delivery delay in underground DTN using network coding. Unlike existing works that only use the contact-based model, we adopt the random walk on 2-D grid model as our mobility model. We define the innovativeness of a node as the number of new packet it can bring to the destination and derive the network state dynamics based on this definition. The simulations show that our analytic approach has better prediction to the delay performance.

Robust stability criteria of uncertain fractional-order system with is investigated based on LMI technique. Furthermore, robust synchronization of uncertain fractional-order complex networks is discussed based on the LMI technique. Finally, numerical example is given to illustrate the effectiveness of the proposed methods.

Abstract: Retracted paper: In order to realize the fast and accurate communication between AB SLC500 PLC and Profibus network, this thesis studies the Profibus protocol and develops the Profibus application program in the Flex I/O module. Thus the communication between SLC500 PLC and Profibus network is realized. Compared with the applying of SLC500 to control the other equipments and network, the applying of the Flex I/O module promotes the controlling efficiency and responding rate and realizes the complete control of the controlling system. The result of this research shows that this plan can ensure the accuracy, reliability and efficiency of the data transported.
