According to IEEE micromouse standards, micromouse needs to find the shortest path in the maze that has been searched, and sprint with the fastest velocity, the shortest path and the least number of turns. To ensure the shortest path of micromouse in the maze that has been explored, it is necessary to plan the existing paths. Therefore, an Oblique sprint algorithm with eight directions is proposed in this article. The algorithm divides the maze cell into eight directions, records the running direction of the micromouse in the maze, finds out the shortest path through the contour map, makes the direction map on this path, and then integrates the direction map into the actual running action. Through this algorithm, the optimal design of sprint path and action mode is realized. By comparing with the traditional algorithm, it is demonstrated that the new algorithm solved the problems of the traditional sprint algorithm, such as long distance and many actions, reduced the number of turns, and improved the sprint efficiency of micromouse in the maze.

Increasing the breaking speed of the HVDC circuit breaker in the DC grid can provide an additional necessary time for other control strategies of the VSC-HVDC system during fault conditions. This paper presents a new fault local detection and power line protection control strategy for HVDC breakers based on Zhangbei four-terminal flexible HVDC transmission project. This method determines if the line has faults by monitoring the rate of change of voltage (ROCOV) at both ends of the DC line. And this method can realize fault local judgment and improve the speed of protection operation. In addition, the method of distinguishing the faults of adjacent lines, busbars and local lines is specifically proposed, and the accuracy of the proposed method and the selectivity, reliability and speed of protection actions are verified by PSCAD under different working conditions. For a flexible HVDC system which needs to quickly clear the fault, this method provides a new research idea for rapid self-breaking control strategy of DC circuit breaker.

This paper presents a design paradigm for the 2-D (two-dimensional) FIR (finite impulse response) notch filter using Hopfield neural network. A Hopfield neural network is chosen and the relationship between the least squares error criterion and the Lyapunov energy function is established. The design problem is transformed into the problem of finding the minimum value of the Lyapunov energy function. When the minimum value of the Lyapunov energy function is obtained, the outputs of the Hopfield neural network are the coefficients of the 2-D FIR notch filter. The complexity of computation can be reduced by using the Hopfield neural network. The simulation results demonstrate the effectiveness of the proposed algorithm.

Beamforming has been widely studied in wireless communications, radar, sonar, and other array systems. Digital beamforming is usually designed based on the array response and the estimation of the covariance matrix of the received signal. Various model mismatch issues can arise due to unequal antenna gains, phase errors, direction-or-arrival (DOA) mismatch and imperfect estimation of the covariance matrix. Different methods based on the shrinkage estimation of the covariance matrix and interference-plus-noise covariance matrix reconstruction have been proposed to address the challenges. In this paper, we investigate the robustness of several approaches in the presence of model uncertainties. We demonstrate the pros and cons of those approaches under different scenarios, based on which recommendation on the choice of the proper method may be made.

At present, DC supply technology has become a research hotspot again. And the wide application of all-controlling power electronics devices also makes DC distribution system usher in a new opportunity for development. Through the analysis of the possible power quality problems existing in DC power distribution network, a set of comprehensive evaluating method for DC power quality is proposed in this paper. To avoid the excessive subjectivity or objectivity of weight coefficients, the combination weighting method based on maximizing deviation is adopted to allocate the subjective and objective weight proportion fairly, thus making the decision of comprehensive weights more accurate. Fuzzy matter-element model is built to evaluate power quality of DC distribution network in order to solve the problems in DC power quality evaluation process, such as fuzziness and uncertainty. Finally, numerical examples show that the proposed comprehensive evaluation model can be used to evaluate DC power quality with feasible and practicability results.

Microbial power generation is the use of microbial energy to generate electricity. This paper is mainly designed to study the microbial power generation system in the energy storage system. Microbial power generation voltage is only 0.6v and this voltage is very small, The electricity from the microbes is first charged by a group of parallel super capacitors. Then the super capacitor is transformed into a series state, and then through the DC-DC boost circuit to store electricity. This can store electricity exponentially and Long time power supply for load. This process, the switching of the series and parallel state of the super capacitor is controlled by a single cylinder which is connected with the circuit. The whole system can raise the voltage of microbes from 0.6V to 15V.In addition, the energy storage scheme discussed in this paper has practical guiding significance, and can guide the production of the corresponding objects.

We consider the problem of distributed signal detection in a wireless radar sensor network with sensors having non-ideal communication links to the fusion center. Other than the research of the optimum detection scheme, we focus on the efficient transmission of given sensor decisions at the cost of slightly lowering the detection probability at the fusion center. To do so, we introduced two quantities, i.e., detection probability loss coefficientand communication gain coefficient. By studying their curve, an efficient transmission scheme can be found with detection probability loss less than a prescribed small value. A procedure was given, and the simulation results illustrated the effectiveness of the proposed method.

Spaceborne dual-antenna uses satellite as platform, and the satellite center extends two antennas to both sides at the same time. The first antenna transmitting and receiving antenna while the second antenna is installed the other end. The antenna arm is used to form an interferometric baseline. Synthetic aperture radar (SAR) interferometry is achieved by using antennas at both ends of antenna arm transmitting and receiving signals. Comparing with SRTM system [1], [2], which extends a 60-meter antenna arm to form an interference baseline for interferometry, the new system will have better performance. But during the flight, the attitude adjustment of the engine will cause the antenna mast motion, which will affect the SAR imaging and interferometry. The relatively regular slow motion can be compensated, but the fast motion is difficult to measure because of randomness. So we should analysis the effect of fast antenna mast motion in this system. In this paper, the amplitude and frequency threshold model of the antenna fast mast motion in dual-antenna SAR system is proposed by theoretical derivation. At the same time, the accuracy of the theoretical analysis is verified by the simulation experiment of the whole process, which provides theoretical support for design of dual-antenna system.

Aiming at path planning and collision avoidance of multiple autonomous underwater vehicle (AUV) system under complex environment, an improved neural network algorithm based on biological inspired model is proposed. Firstly, establishing an improved bio-inspired neural network model, the two-dimensional working area is rasterized, and each grid and neuron are one-to-one correspondence, stipulating that the interest area and the obstacle area of the grid correspond to the excitatory and inhibition of neurons respectively, affecting the neurons activity in the whole working area by the transversal function of the adjacent neurons each other. Secondly, AUV plans a safe and collision-free path by comparing the size of the activity of neighbor neurons. Then, Aiming at the problem that AUV moves clinging to the edge of obstacles, adding lateral inhibitory effects of the obstacles on the neural network and greatly improving the safety and rationality of the path planning. Finally, changing the property of grid positions of each AUV in real time to realize collision avoidance between multi-AUV. Simulation experiments prove that the improved algorithm is valid about the path planning in this thesis and the large allowance collision avoidance problem in a complex environment with single-AUV and multi-AUV.
