In order to improve the marine power system robustness for varying parameters, and attenuate the persistent disturbances effect on power system stability. In this paper, based on the nonlinear robust model of the power system including static load, the storage functions of the system are constructed by integrating nonlinear L2 gain disturbances attenuation theory smoothly into backstepping design methodology. A nonlinear robust controller law are obtained. The controller reflects the nonlinearity of the system and decreases the impact of the disturbances. The simulation results show that the closed-loop system has the ability to attenuate the disturbance using the controller and can resume stable state rapidly when large disturbances happen.

The 3D solid model of the thin cut closed ring is established, and the meshing procedure of the thin cut closed ring is analyzed with the software ANSYS. The meshing forces and stresses and the x direction displacements and y direction displacements are calculated, and the radial displacements are calculated through matrix operations, too. Corrected model of the thin cut closed ring is established. The radial displacements along the thin cut closed ring are recalculated, then the 3D solid model of the thin cut closed ring is remodified. The heat-bend moulding typical values with error less than 0.03mm are obtained after two approximation calculations. It plays a guiding role in precise design and manufacture of the thin cut closed ring.

This paper proposes a self-adaptive and energy efficient routing approach for a wireless sensor network. In our approach, every sensor node maintains a table of neighbor nodes' attributes, including energy left, least hop count toward sink node and current state, a sensor node chooses neighbor nodes as data relay nodes according to energy left, hop count and failure rate factors, and a sensor node sleeps when idle for saving energy. In order to guarantee the QoS of the whole network, acknowledgement and retry mechanism are used to make sure data is sent successfully. Furthermore, a sink node collects and evaluates failure rate of the network regularly to support slow mobility. When the failure rate is above the threshold that is determined by different application situation, the network topology will be rebuilt. The simulation experiment shows that our adaptive algorithm is scalable and efficient.

Aiming at the control variables of reactive power optimization are discrete, and some parameters in the standard particle swarm optimization (PSO) algorithm need to be predefined by test, so the algorithm's practicability is restricted. For these reasons, an adaptive particle swarm optimization (APSO) algorithm is proposed by the authors. APSO introduces the self-adaptive tuning strategy and boundary constraint conditions can find the global optimal solution and solve the discrete variables. The reactive power optimization results of the standard IEEE-30-bus power system show that APSO is efficient than standard PSO. The global convergence accuracy and convergence stability is obviously improved compared with that of PSO.

The signal measured from Magnetic Resonance Sounding (MRS) instruments needs to process by the digital filter. There are three methods to be used in MRS instruments, include adaptive north filter, moving average filter and FIR low-pass filter. Through building the ideal model adding several normal noises in MRS signal analyses what kind of method adapts what kind of noise. According to the value of SNR, the decay situation of spectrum amplitude, the adaptabilities of various filtering methods are summed up. At the same time, the actual measurement data also proves the strategy basing on the ideal model, at final, adaptive filter methods for several noises is put forward.
