Satellite attitude determination is one of the key parts of control system design. Star sensor (STS) is one of the high-precision attitude measurement instruments. However, the STS fixed on the load platform rotate and is frequently affected by solar radiation, earth atmosphere radiation and other factors, which is not conducive to the accuracy of satellite high-precision attitude determination. In view of the above problems, many factors are considered comprehensively, and the layout design of STS fixed on rotation platform is proposed in this paper. There are four STS adopted, and the angle between the optical axis conic pendulum curve of two STSs in each group is greater than or equal to 70° at the intersection of the satellite X-axis and the solar plane, which is equal to twice the stray light suppression angle of STSs, and the angle of any two STSs is as close to 90° as possible in geometric space. Based on the layout scheme, it is ensured that the sunlight doesn’t enter each STS at the same time. The results of STK simulation show that the layout scheme is reasonable and feasible, and is suitable for the influence of different seasonal. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Magnetically suspended control moment gyroscope (MSCMG) is a multivariable, strong coupling and nonlinear complex system. The vibration force is generated by multi-source disturbances such as residual mass unbalance and sensor error entering the closed-loop control system through different paths. The existing research work on dynamic modeling and harmonic vibration suppression of magnetically suspended rotor system is mostly based on the approximate linearization model of magnetic bearing force. When MSCMG outputs large torque, excessive rotor displacement runout will aggravate the nonlinear degree of magnetic bearing force, and seriously affect the suppression accuracy of harmonic vibration force of magnetically suspended rotor system. Therefore, it is necessary to establish a nonlinear dynamic model of magnetic bearing force and analyze its impact on the vibration force, and provide a theoretical basis for the research of harmonic vibration force suppression algorithm. © 2023 IEEE.

Few-shot electromagnetic signal classification:A data union augmentation method

Chinese Journal of Aeronautics 2022年第9期35卷 49-57页

Deep learning has been fully verified and accepted in the field of electromagnetic signal classification. However, in many specific scenarios, such as radio resource management for aircraft communications, labeled data are difficult to obtain, which makes the best deep learning methods at present seem almost powerless, because these methods need a large amount of labeled data for training. When the training dataset is small, it is highly possible to fall into overfitting, which causes performance degradation of the deep neural network. For few-shot electromagnetic signal classification, data augmentation is one of the most intuitive countermeasures. In this work, a generative adversarial network based on the data augmentation method is proposed to achieve better classification performance for electromagnetic signals. Based on the similarity principle, a screening mechanism is established to obtain high-quality generated signals. Then, a data union augmentation algorithm is designed by introducing spatiotemporally flipped shapes of the signal. To verify the effectiveness of the proposed data augmentation algorithm, experiments are conducted on the RADIOML 2016.04C dataset and real-world ACARS dataset. The experimental results show that the proposed method significantly improves the performance of few-shot electromagnetic signal classification.

In this paper, the attack detection problem is investigated for a class of closed-loop systems subjected to unknownbutbounded noises in the presence of stealthy attacks. The measurement outputs from the sensors are quantized before transmission.A specific type of perfect stealthy attack, which meets certain rather stringent conditions, is taken into account. Such attacks could be injected by adversaries into both the sensor-toestimator and controller-to-actuator channels, with the aim of disrupting the normal data flow. For the purpose of defending against these perfect stealthy attacks, a novel scheme based on watermarks is developed. This scheme includes the injection of watermarks(applied to data prior to quantization) and the recovery of data(implemented before the data reaches the estimator).The watermark-based scheme is designed to be both timevarying and hidden from adversaries through incorporating a time-varying and bounded watermark signal. Subsequently, a watermark-based attack detection strategy is proposed which thoroughly considers the characteristics of perfect stealthy attacks,thereby ensuring that an alarm is activated upon the occurrence of such attacks. An example is provided to demonstrate the efficacy of the proposed mechanism for detecting attacks.

The deployments of deep learning models must be highly optimized by experts or hardware suppliers before being used in practice, and it has always been a long-term goal for the compiler community to enable compilers to automatically optimize code. However, there is no feasible solution in practice as running a program costs a considerable amount of optimization time to obtain a desired latency. Aiming at making up for the deficiency of long optimization time of TVM compiler, a novel optimized hybrid aging evolutionary algorithm is proposed to predict the running time of the code and accelerate automatic code optimization for Ansor, an auto-tuning framework for TVM. The algorithm alternately removes the worst and oldest individuals in the population during the evolution process. Unlike previous evolutionary algorithm, if an individual seeks to survive in the evolving population for a long time, it must have excellent scalability and flexibility, not just the individual's own adaptability. In this way, this algorithm not only ensures a strong search capability, but also improves the convergence speed and accuracy, significantly reducing the optimization time of tensor programs for deep learning inference. Experimental results show that the algorithm can accelerate convergence speed. For the same task, our algorithm provides 9% to 16% shorter optimization time on average while achieving similar or better optimization quality (i.e., inference time). © 2023 SPIE.

With development of aerospace industry, the mass of liquid fuel carried by spacecraft is also increasing in order to complete more complex space exploration missions, such as on-orbit refueling and space debris removal. And there is large liquid fuel consumption when spacecraft completes attitude and orbit maneuver, which greatly increases the nonlinearity and uncertainty of spacecraft dynamics and brings great challenges to spacecraft attitude maneuver control. Considering that during attitude maneuver, the control torque is easy to stimulate the liquid slosh, which will affect the attitude control performance and even lead to instability of the system. So it is necessary to constrain the angular velocity during attitude maneuver. In this paper, we consider the large angle attitude maneuver control of liquid-filled spacecraft system. Because of the consumption of liquid fuel, then the mass property of system is unknown and slowly time varying. So a novel finite-time attitude maneuver control law based on barrier Lyapunov function (BLF) and backstepping method in the presence of unknown, time varying system dynamics and angular velocity constraint, which aims at avoidance of violent liquid slosh, is proposed in this paper. Firstly, the sloshing liquid in a partially filled tank carried by the spacecraft is equivalent to a sloshing slug - a sphere of uniform density with a variable radius, and the rigid-liquid coupling dynamic equations with unknown parameters of the spacecraft are deduced by using the law of conservation of moment of momentum. Secondly, a finite-time prescribed performance function (FTPPF) is proposed to guarantee the convergence of spacecraft attitude error to zero within the setting time, with the help of FTPPF and the angular velocity constraint, a time-varying BLF and a logarithmic BLF are proposed correspondingly. Furthermore, a backstepping control law is designed for the spacecraft attitude maneuver based on augmented Lyapunov functions, mean
