In order to study the effect of backlash nonlinear on resonance frequency of electric actuator transmission system then Finally in the premise of meeting the stability the dynamic equilibrium equation of transmission system with backlash is established it makes dynamic simulation analysis for the transmission system based on virtual prototype technology it establishes balanced equation of dynamics system with backlash the effect of backlash on system natural frequency and resonance frequency and the theoretical values and simulation values are compared. Theoretical analysis and simulation results show that the theoretical analysis is basically consistent with simulation results when it is zero backlash and does some theory research and dynamic analysis of backlash nonlinearity and system natural frequency and resonance frequency. First and the error of theoretical analysis and simulation results is within 10%. Therefore according to describing function to theoretically model the backlash nonlinear it can be concluded that considering the transmission system theoretical analysis of backlash nonlinearity is feasible the relation between describing function and the amount of backlash and input amplitude is analyzed and it is much closer to the actual system with instructive significance. 2011 IEEE.

In this paper we present a novel combination of intuitionistic fuzzy Description Logics with intuitionistic fuzzy logic programs which yields a more realistic and intelligent hybrid system whitch offers the best of both aspects: the extension of Description Logics with intuitionistic fuzzy sets are suitable for describing vague and imprecise concepts in a given domain on the other hand inuitionistic fuzzy logic programs suffice for rules with vague atoms. We show that the new formalism remains faithful to both individual intuitionistic fuzzy components and we provide the decidability and complexity of the framework under some suitable assumptions. 2011 IEEE.

Two manipulators handling a flexible payload are studied based on adaptive backstepping control theory. Considering the complexity of the dynamic model the obtained model is divided into a slow subsystem describing the large rigid motion and a fast subsystem expressing the elastic vibration by singular perturbation theory. A cooperative controller is designed based on adaptive backstepping control. The slow subsystem can complete system trajectory tracking performance. The fast subsystem can suppress the elastic vibration of the system. Stability of the system is proved by using Lyapunov stability theory. The validity of the proposed scheme is demonstrated by simulations. 2010 IEEE.

In order to obtain high quality pictures the thermal design is necessary for the space telescope. The designed temperature scope should meet to the permissible temperature tolerance of the telescope. A method for calculating the permissible temperature tolerance of the telescope is studied. The calculating temperature tolerance will be targeted for space thermal environment adaptive structure design and thermal design. A method for describing the temperature fields of the telescope is introduced. The descriptive temperature fields are able to include every temperature states that the telescope endured on orbit. When the MTF (Modulation Transfer Function) just meet to the optical indicator the ultimate temperature tolerance of the space telescope is obtained that is the aim temperature scope for the thermal design is obtained. 2009 IEEE.

This paper presents a master-slave multi-communication system designed with several micro-controllers used as master and slave controllers to set signal the lamp to realize point-to-point communication through the RS422 interface. By describing a typical example of this system and the blue print of hardware and the flowchart of software the reliable work of the system has been proved. The circuits of system are very simple and practical and they can be used to realize all the functions of a pilotless airborne mapping equipment. It also has a strong anti-jamming capability due to its balanced transfer scheme with single transmitter and multiple receivers. It is very efficient in protecting the integrity and correctness of transmitted and received signals avoiding the collision of signals through the bus satisfying the communication among several micro-controllers in a single system and forming a special communication network. 2009 SPIE.

Fuzzy controller was used to resolve the problem of fast tracking and overshoot in electric-driven simulation turntable for its essence belongs to PD control In this system the control rules of fuzzy controller were established according to the step dynamic response process for the speed loop of this system was predigested to be second-orders system. The describing function method was adopted to analyze the stability of the fuzzy control system. It gave the information of stability of system intuitively. The fuzzy controller had been applied in this system successfully. The simulation turntable had no overshooting nearly when its step input signal was close to 90. Experimental results show the implementation method of fuzzy controller is not only simple but also effectual in engineering practice. It also provides an approach of design of fuzzy controller for motion control system. 2008 IEEE.
