This paper proposes a real-time integrated energy system (IES) management approach which aims at promoting overall energy efficiency, increasing renewable energy penetration, and smoothing load fluctuation. The electric vehicles (EVs) charging scheduling is incorporated into the IES management, where the uncertain arrivals and departures of multiple EVs are considered as a stochastic but flexible load to the IES. Furthermore, towards the carbon neutralization target, a carbon emissions trading mechanism is introduced into the IES management to incentivize the system to operate in an eco-friendlier manner. To tackle the computational complexity induced by the stochastic and intermittent nature of the renewable energy sources and EVs load, the scheduling of the IES is realized in a neural network based real-time manner, driven by a deep reinforcement learning approach that guarantees safe training and operation. The case study verifies the effectiveness of the proposed approach. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Multi-stack fuel cell system(MFCS) are an important basis for large-scale application of solid oxide fuel cell(SOFC) technology, MFCS can provide higher system power and longer service life. As the number of stacks increases, different topologies can be formed between stacks, including parallel structures and series structures, and the physical characteristics of MFCS will also change. In this study, the degradation of the stacks is first considered, and the system model of series structure and parallel structure including the degradation of the stacks is built. The parallel structure proposed in this paper is the key to ensure the high efficiency and long lifetime of MFCS. Through the simulation of systems with different topologies, it is found that the power generation efficiency of the systems caused by the topologies varies greatly in different output power stages. The efficiency of the parallel structure in the low power stage is significantly better than that of the series structure, and the parallel structure is more conducive to the high efficiency of the system in the whole stage. Different topological structures also have a greater impact on the degradation of stacks. The degradation rates of stacks in parallel structures are close to each other, and the state of stacks is more consistent. The overall life of the system in parallel structures is also better than that in series structures. © 2024 Technical Committee on control Theory, Chinese Association of Automation.

A trajectory optimization method under complex disturbance is proposed for the future high-mass Mars entry vehicles. First, the dynamic model for the high-mass Mars entry vehicle with a supersonic inflatable aerodynamic decelerator (SIAD) is established. Then, an orthogonal array of three levels with four variables is used to consider the hybrid disturbances of the aerodynamic parameters, and a sensitivity formula is designed to quantify the sensitivity of the bank angle to the hybrid disturbances. With an anti-windup index based on the sensitivity formula and a terminal constraint index together, a comprehensive index is obtained to solve the anti-windup trajectory optimization problem. Finally, the anti-windup trajectory optimization method is simulated and compared with the traditional method. The results show that the proposed method can reduce the sensitivity of aerodynamic disturbance and improve the tracking performance of drag acceleration. © 2023 Technical Committee on control Theory, Chinese Association of Automation.

In non-cooperative scenarios, wideband frequency hopping (FH) communication reconnaissance including FH signal detection, parameter estimation, and network sorting under single-channel reception is challenging. The FH pattern contains the most information about FH signals. So it is the core of FH parameter estimation. Based on the task analysis, this paper proposes a blind prediction framework combining deep learning (DL) and clustering methods to improve the accuracy and efficiency of FH pattern estimation for mixed signals in the wideband spectrum. The unique advantage of this framework is that it requires no prior signal information and anchors but exploits the inherent time-frequency (TF) properties of asynchronous FH signals. It has a strong generalization ability and can adapt to signals of any shape. Moreover, a new comprehensive evaluation metric, normalized root mean square error including missed detection (NRMSE-MD), suitable for sequence data prediction is proposed to evaluate the level of missed detection and false detection in signal monitoring. Experimental results demonstrate the superiority of the proposed framework and the effectiveness of the proposed evaluation metric. © 2023 IEEE.

In this paper, an inverse synthetic aperture radar imaging method based on multiple norm constrained generalized orthogonal matching pursuit (MNGOMP) algorithm is proposed to improve the imaging process of inverse synthetic aperture radar is prone to noise interference in compressed sensing environment. Orthogonal matching pursuit (OMP) and generalized orthogonal matching pursuit (GOMP) converge slowly in radar imaging and are susceptible to noise interference. Therefore, multiple norm constraints were introduced into the iteration update to improve convergence speed and accuracy and enhance noise resistance. The results show that this method is effective in suppressing unnecessary clutter and enhancing desired target. © 2023 IEEE.

Aiming at the problem of poor anti-noise interference ability of linear FM fuzes, the noise FM interference suppression method based on adaptive trap is proposed, and the adaptive trap is applied to linear FM fuzes for the single-frequency characteristics of linear FM fuzes generated by the frequency-checking signals. By adaptively adjusting the weights of the trap, the trap has a trapping characteristic at the frequency Dian of the differential frequency signal, so as to achieve the effect of noise FM interference suppression, and experiments show that the algorithm can recover the target echo signal when the interference signal is stronger than the target echo by 10 dB. © 2023 IEEE.

Aiming at velocity/height tracking control and attitude stabilization for the longitudinal flight of cruise vehicle, the research of intelligent flight control method is carried out by combining the backstepping control theory and the deep reinforcement learning method. Firstly, the longitudinal flight control system of the vehicle is decomposed into velocity and height subsystems, and the control law is designed based on backstepping control theory. Then, aiming at the problems that the selection of the multiple control gains will directly affect the control performance of the closed-loop system and the adjustment process of control gains is cumbersome, the twin delayed deep deterministic policy gradient algorithm (TD3) will be adopted to train the cruise vehicle, so that it can determine the control gains online according to the current flight states. The numerical simulation results show that, the proposed intelligent flight control method can guarantee the high-precision tracking with respect to height and velocity commands, and also realize the attitude stability of cruise vehicle. © 2023 IEEE.

This paper presents a new method to achieve passive pulse compression using a lossless dielectric loaded waveguide (DLW). The method demonstrates an obvious performance in controlling the dispersion characteristics of the DLWs. Efficient pulse compression in a specific frequency range is achieved by varying the radius and thickness. In the simulation, the compression factor of 85.6 is obtained by compressing a linear frequency-modulated pulse with a duration of 20 ns and a frequency range of 34.8-39.8 GHz into a Gaussian-envelope pulse. © 2023 IEEE.
