This paper considers an improved Kalman filter (KF) for a non-Gaussian system, when an adaptive statistics model is applied to capture the systematic characteristics in real time. The problem is formulated as self-adaptive adjustment parameters (SAPs) updating by the recursive least squares (RLS) algorithm. These parameters are shown to admit adaptive statistics model to characteristics of which applies and extends results given earlier in “Online denoising based on the second-order adaptive statistics model” (S. L. Yi and X. B. Jin et al., Sensors, 17(7), 1668, 2017.). Simulations comparing the improved KF based on the SAPs to the standard KF and the past algorithm illustrate a satisfactory performance when applied to self-adaptive adjustment parameters. Simulation results show that the proposed algorithm can gradually converge with a small performance loss.
本文研究了一种用于非高斯系统的改进卡尔曼滤波器(KF),该滤波器采用自适应统计模型来实时捕捉系统特征。将该问题表述为用递归最小二乘(RLS)算法更新自适应调整参数。这些参数表明,自适应统计模型的特征适用并扩展了前面“基于二阶自适应统计模型的在线去噪”中给出的结果(S. L. Yi和X. B. Jin等人,传感器,17(7),1668,2017)。将基于SAPs的改进KF算法与标准KF算法和过去的算法进行了仿真比较,结果表明,在自适应调整参数时,改进的KF算法具有令人满意的性能。仿真结果表明,该算法能以较小的性能损失逐步收敛。

We investigate the circle surrounding control problem of multiple targets, in which communication topology is undirected and connected. First of all, an estimator is given for each agent to obtain the geometric center of multiple targets in a finite time. Combined with such an estimator, a distributed controller is presented such that all agents can achieve a circular formation and rotate around the geometric center of multiple targets. Meanwhile, agents enclose all targets. Especially, the position of each agent in circular formation can be arbitrary arranged by adjusting the time-varying coefficients. Simulations demonstrate the correctness of the estimator and the surrounding control protocol.

In this paper, a K-filter observer based optimal robust guarantee cost controller is proposed for uncertain nonlinear servo system with immeasurable states to achieve the precision load tracking. By using a K-filter observer to estimate both the system states and the nonlinearities, an adaptive dynamic surface control is designed to make the system output track a given reference command. However, since the parameter uncertainties may influence the system tracking performance, an optimal robust guarantee cost control is developed to combine with the adaptive dynamic surface control to stabilize the uncertain system and guarantee the system cost function less than or equal to a given upper bound. The Lyapunov theory proves the stability of the closed-loop control system. Simulation results based on a servo system are conducted to illustrate the efficiency of the proposed control scheme.

This paper studies configuration design, relative navigation and control of non-cooperative flying-around mission $J_{4}$-perturbed elliptic orbit. $J_{2}$-perturbation is generally considered in most circumstances of satellites around the Earth, while the relative motion is under $J_{4}$-pertuabation to achieve more precise results. The key problem of flying-around mission is orbital control, a more general method is established which considers remote maneuvers, reconfiguration, flying-around and escape. Based on the orbital control in the paper, the initial conditions of object and tracking satellite are as appropriate but not unique. The Extended Kalman Filter is introduced to enhance the robustness of relative navigation system in cases of noises and errors caused by the measurements. With the introduce of Extended Kalman Filter in relative navigation and $J_{4}$ perturbation in relative motion, simulation results of the flying-around mission configuration design are more persuasive.

The classical Hazard Rate Function (HRF) is typically used to make preventative maintenance (PM) decisions and always estimates HRF based on time to failure data. Even so, PM determination using conventional HRF is not suitable for systems with condition monitoring. The system is stopped checking and maintaining when the measured health state exceeds a predetermined threshold, which is always referred to as a soft failure. Since the application of HRF for PM decision making has great advantages, the classic HRF should be extended to combine soft and hard failure of systems with condition monitoring. In this paper, we define the HRFs of hard and soft failure for system under condition monitoring and propose a method to estimate the HRFs with data of failure time. We discuss in detail the relationship between these two HRFs and the classical HRF. With double stochastic processes (processes of degradation and measured healthy status), the properties of these HRFs are also researched. Further the optimal maintenance decisions are made for non-repairable and repairable systems upon these two types of HRFs. Eventually, the idea of this paper is verified by numerical examples.

It is difficult for conventional data mining methods to find out non-frequent and long-sequence satellite telemetry anomaly morphology, and the mining results are not compact and lack of time continuity. In this paper, an anomaly morphology extraction algorithm NPGM-AMEA for telemetry data based on normal pattern gap mining is proposed. Firstly, the satellite telemetry parameters are discretized by KT-Means algorithm, and the original telemetry parameters are converted into feature strings. Secondly, the feature pattern mining is carried out to obtain the feature pattern of telemetry normal sequence, that is, the frequent closure of feature string;Then, the gap between adjacent normal feature modes is located to obtain the location of the abnormal pattern; Finally, the abnormal feature string between the normal mode gaps are extracted and the abnormal curve shape of telemetry state is obtained by matching the abnormal feature string with the time series data. The correctness and reliability of the method are verified by the simulation experiment of abnormal shape mining of the telemetry parameters of a certain type of satellite.

The vehicle detection and tracking are important tasks in intelligent transportation system. The traditional methods of vehicle detection often cause the coarse-grained results due to suffering from the complex environments. YOLO is a pragmatic approach to multi-target detection with a simple and effective algorithm. This paper use YOLO to detect the moving vehicles and use a modified Kalman filter algorithm to dynamically track the detected vehicles, achieving overall competitive performance in day or night. The experimental results show the method is robust to occluding vehicles or congested roads and can obtain 92.11% average accuracy of vehicle counting at 2.55 fps speed.

Lithium-ion batteriesare widely used in our daily life. However, with the frequent use of lithium battery, the performance of lithium battery decreases due to the change of internal physical properties. The most intuitive result is that the capacity gradually decreases with the use of the battery. Therefore, timely and effective prediction of lithium-ion battery remaining useful life (RUL) is particularly important. In this paper, two new health indexes (HI), namely, discharging time difference of equal voltage interval (DtD_EVI) and discharging temperature difference of equal time interval (DTD_EtI), are proposed to represent the degradation process of lithium battery. Pearson correlation coefficient is used to analyze the relationship between these two health indexes and capacity, and then support vector regression (SVR) is used to establish the RUL regression model. Finally, the validity of the proposed method is verified by analyzing the lithium battery dataset of NASA.
