A neural network adaptive inverse controller structure is proposed to solve the problems that hypersonic aircraft with highly nonlinear and flight conditions of large span. OS-ELM algorithm is improved with RBF network for online learning and adaptive inverse controller for the online training is used. Hypersonic aircraft with six degrees of freedom non-linear model is used to verify the performance of adaptive inverse controller.

The mathematical modeling and simulation usually gets a high-index differential-algebraic equation (DAE) system. The structural index reduction algorithms can reduce high-index DAE to low-index DAE. In order to solve the failure of the structural index reduction algorithms in some cases, the authors firstly analyze the combinatorial relaxation algorithm. Then some key algorithms in the implementation of the combinatorial relaxation algorithm are analyzed. Finally, the result of an example shows that the combinatorial relaxation algorithm is an effective way to improve the stability and suitability of the index reduction algorithm based on structural index in DAE.

Considers the power system has nonlinear and uncertain disturbance, a nonlinear controller is designed combined with extended state observer (ESO), back-stepping and sliding mode. The nonlinear extended state observer is applied to estimate and compensate uncertainties in real time, thus improved both robustness and adaptability. The controller can hold the power system stability on conditions of Lyapunov function; a new sliding surface is designed. The whole control law can be obtained by applying the sliding mode control theory and the disturbance is attenuated. Simulation results show that proposed control method not only can improve the voltage and power angle stability greatly compared to the conventional control methods but also can restrain effectively unknown disturbance.

A new capsule robot prototype with function of radial clearance compensation driven by external rotating magnetic field is proposed, based on the established fluid dynamic model, fluid dynamic pressure and swimming speed of the robot with respect to the clearance between the inner pipe wall and the surface of the robot is analyzed. According to the phenomenon that axial propulsion reduces greatly by the increase of radial clearance between inner pipe wall and external surface of the robot, the startup characteristics is investigated. Theoretical analysis and experimental results show that the control on propulsion and swimming speed of the robot is realized by reducing the thickness of dynamic oil membrane through radial clearance self-compensation, and driving performance of the robot is modified greatly.

The use of consistency techniques is the main feature of any Constraint Satisfaction Problems(CSPs)solver. Arc Consistency (AC) applied to preprocessing can reduce the search space by removingthe values which are arc inconsistent. Singleton Arc Consistency (SAC) is a stronger level of consistencythan AC. Arc consistency technique with heuristic strategy has been proved to be an efficient techniqueto improve the efficiency of algorithms. In this paper, we first study the well-known SAC-3 algorithm indetail, and propose two algorithms with heuristic strategies for the drawbacks in SAC-3, SAC-3-FFPand SAC-3-MINIsup. Then, we give the correctness proof and complexity analysis. In the end, we implement the two algorithms in some random CSPs and benchmarks during the preprocessing step. Experimental results show that the two algorithms perform better than SAC-3 for most test cases.

The paper indicates a self-developed testing system of reaction time based on the theory of mesopic vision. The system is supposed to simulate the actual effects of tunnel lighting with varies of light sources, which could be attributed to mesopic visual environment. By adopting lights of different brightness, projecting designated graphs on the screen and capturing reaction time with a button, the effect of lighting condition to the human body can be obtained. The system equips with software, in which diverse projects can be created and also all the parameters and data can be put into a chart for later research. By providing theories and sequential experiments, the paper introduces hardware and software composition of the developed system. It is proved by facts that this system could throw light in the field of mesopic vision.
