To effectively diagnose the aircraft structure components fatigue damages, a new kind of health diagnosis approach for the aircraft, based on experience modal decomposition (EMD) and probabilistic neural network (PNN), is proposed in this paper. The advanced acoustic emission (AE) technique is used to monitor the aircraft stabilizer health state and get the AE information. And the AE information from the aircraft stabilizer is decomposed into the limited inherent modality function (IMF) by the EMD, which is quite fit for dealing with the non-linear and non-steady signal. The IMF energy is extracted to construct the eigenvectors. Then the health status of the aircraft can be diagnosed with the eigenvectors by PNN health monitor. Experiments show that this method can effectively monitor the fatigue crack of the aircraft stabilizer. It presents a new approach to diagnose effectively health state of aircraft structure components.

The paper presents a vehicle yaw stability control strategy devoted to prevent vehicles from spinning and drifting out. The yaw stability control system is integrated with active torque distribution and differential braking system. Active torque distribution systems utilize active differentials to independently control the drive torque distributed to each drive wheel and thus provide active control of both traction and yaw moment. However, if the coefficient of road friction were small or if the vehicle speed were too high, active torque distribution system may not afford adequate yaw moment to response the driver needs. With this improved integrated control system, the vehicle can afford nice manoeuvrability and stability.

On the basis of research on fuzzy traffic control algorithm for a single intersection, we present a new adjustable multi-phase sequence fuzzy control algorithm. By this method, not only the traffic flow of every phase is considered, but also the green time and red time. Base on this algorithm, a two-stage fuzzy control system which consist of the green time delay module and phase selection module is designed .The first stage chooses a candidate of the green light phase which has the highest emergency degree among all red light phases. the second stage judges to continue to delay or convert green light phase according to the length of the vehicle queue at the current green light phase and the candidate. Computer simulation shows that the new type of fuzzy control algorithm possesses flexible phase combi-nation with little delay, it can solve the imbalance of traffic flow very well at the intersection.

A novel kind of actuator which is used to suppress vibration of ship deck resulted from unbalanced moment of motor or screw propeller is presented in this paper. Frequency and magnitude of exciting force can be adjusted on line. The control equation of the actuator system is non-linear. For eliminating the effect of variation of system parameters and external disturbance on tracking capability, sliding mode control is introduced in the servo control system. In order to attenuate the chattering phenomena, reaching law is used to track the trajectory of position and velocity of the actuator. Simulation and experiments study have been carried out to evaluate the performance of the sliding mode controller, and the results show that the controller has achieved a performance with minimum reaching time and smooth control actions. In addition, the results also revealed that the controller has strong effectiveness and robustness of the trajectory tracking.

Using the conservation law, the theories of high temperature gas dynamics, fluid mechanics, the physical and mathematical turbulence flow field model is set up to simulate the tunnel fire and its smoke flow. An experimental fire in a tunnel is studied in light of the turbulent flow model. The results indicate that the turbulent flow field model is better than before and has prettily good consistency with the experimental data. Through the numerical simulation analysis, it is concluded that the fully developed smoke flow downstream can clearly present the distribution of layered temperature, concentration of CO2 downwind and smoke flow velocity.
