Classical adaptive algorithms have good convergence performance in linear regression system identification. However, they will face performance degradation while dealing with censored data since only incomplete information can be obtained. In this paper, the least mean M-estimate algorithm for censored regression (CR-LMM) is proposed for the robust parameter estimation. To compensate for the bias caused by censored observation, the probit regression model is employed to derive the estimated error for constructing the M-estimate cost function. The cost function can expel the adverse impact of the impulsive noise, and it is solved by the unconstrained optimization method. Computer simulations in the impulsive environment are carried out to demonstrate that the proposed CR-LMM algorithm exhibits better convergence performance than the existing algorithms in censored regression system identification scenarios.

Aiming at the problem of high precision and high safety estimation of state of power (SOP) of high-rate lithium-ion power battery in the application of special operation vehicle, this paper analyses the working characteristics of the high-rate lithium-ion power battery, and builds the second-order RC equivalent circuit model of the battery. The recursive least squares (RLS, Recursive Least Squares) algorithm is used to identify battery parameters online, and the SOC algorithm based on the extended Kalman filter and the SOP algorithm are used for joint estimation. This algorithm is used to solve the problem that the maximum allowable power of the actual battery caused by the degradation of battery life is difficult to calculate and even causes the problem of safe fire accidents. Combined with the correction algorithm in practical engineering, it ensures the efficiency and safety of the SOP estimation during the entire life cycle of the electric vehicle. This research has an important significant guiding in engineering practice.

To ensure the performance and reliability of ultra-quiet payloads in orbit, the ground test are usually carried out before launch. However, the gravity unloading system with suspension introduces redundant disturbances into ultra-quiet payloads. The gravity unloading system may affect the vibration isolation performance of the ultra-quiet payloads. To solve the problem of introducing disturbances, a gravity unloading system with high stiffness shelf and ultra-low frequency spring is designed in this paper. Testing results show that the gravity unloading system reduce the redundant disturbances to less than $2mumathrm{g}$ within the frequency range of 0.6-100Hz, which can simultaneously guarantee the gravity unloading function and ultra-quiet environment.

In this paper, based on COMSOL simulation,a simulation model of corona initiation for angular electrodes with different number of tips (quadrangular, hexagonal, octagonal), tip thickness (0.3 cm, 0.5 cm, 0.8 cm), and angle (10.72°, 16°, 20.72°) is established to investigate the effect of changes in the geometry of angular electrodes. The effect of the change of the angle electrode geometry on the corona onset voltage is investigated. By introducing the concept of equivalent radius, the effect of geometric variations in the number of tips, thickness and angle on the corona onset voltage was quantified. It was found that as the number of tips, tip thickness and angle of the angular electrode decreased, the equivalent radius of the angular electrode gradually decreased and the corona onset voltage gradually decreased; variations in the number, thickness, and angle of the unit tip had differences in the degree of influence on the corona voltage, with rates of 3.279%, 2.846%, and 0.678%, respectively.

To evaluate the safety of electromagnetic exposure of a magnetic coupling resonance wireless charging system in electric vehicles on the human central nervous system, COMSOL Multiphysics software is used to establish electric vehicle models with different materials and thicknesses, a magnetic coupling resonance wireless charging system model, and a human body model. The electromagnetic exposure of the electromagnetic field generated by the wireless charging system to the central nervous system of the human body in the electric vehicle with carbon fiber-reinforced plastics (CFRP) car body, aluminum alloy car body, and low carbon steel car body with different thickness shielding is simulated and analyzed. The simulation results show that CFRP, aluminum alloy, and low carbon steel vehicles can effectively shield electromagnetic fields. The shielding effect of CFRP and aluminum alloy car body improves with the increase of thickness, and the shielding effect of low carbon steel car body worsens with the increase of thickness. Under the worst shielding condition, the maximum magnetic induction strength and electric field strength of human head are respectively 0.9 µT and 0.18 V/m the electromagnetic exposure level to the human head is less than the public exposure limit of 27 µT and 2.97 V/m set by the International Commission on Non-Ionizing Radiation Protection. Results show that the magnetic coupling resonance wireless charging system of an electric vehicle will not harm the human central nervous system in the vehicle.

For grid-connected inverter, phase-locked loop (PLL) is a common method to synchronize the output current with the grid voltage. However, in weak grid, as the grid impedance cannot be ignored, the inverter tends to be unstable. Besides, the grid impedance can vary in the actual application, using fixed PLL parameters designed for specific grid condition cannot guarantee the inverter robustness against the grid impedance varying. Hence, this paper aims to propose an improved method to improve the typical single-phase delay-based PLL. At first, the impedance model of the inverter is established and the reason for the system stability deterioration is analyzed in detail. Then, an adaptive PLL is proposed based on the quasi-passive method for grid-impedance measurement. The PI parameters of the PLL have been adaptively adjusted online according to the measured grid impedance so as to achieve the high phase margin (PM, not less than 40°) in the weak grid. Simulation results have proved that the proposed adaptive PLL can ensure the system stability, maintain the high quality of grid current and robustness in the weak grid.

Many studies have shown that the complexity of the webpage design will affect the search efficiency. For e-commerce webpages, the search efficiency is directly related to the purchase rate. Therefore, through eye tracking experiments, this paper studies the influence of density factors of e-commerce webpage complexity on user search behavior performance and subjective perception, establishes the relationship between webpage visual design and user search usability, and comprehensively constructs evaluation indexes from behavior data and perceptual data.

Permanent magnet synchronous motors (PMSM) are widely used in industrial control, household electrical, transportation, aerospace and other fields. The acquisition of rotor position and speed is the key to achieving high-performance control. In view of the disadvantages of the large volume and high cost of photoelectric encoders and magnetic encoders, and the limitations of sensorless control technology, the technology of driving PMSM with low-resolution position sensor can not only control the cost but also ensure the performance of the motor. Therefore, the method of estimating rotor position and speed that can improve its control accuracy and system stability has attracted wide attention from scholars at home and abroad. The working principle of the switch-type Hall position sensor is introduced, and the source of its error is systematically summarized. Taking the method of interpolation, filter and observer as the core, this paper introduces several methods of estimating high-resolution rotor position and speed. Then this paper analyzes their principles, advantages and disadvantages, and applicable conditions. Finally, it summarizes the existing achievements and looks forward to the future development trend.
