Aiming at the reentry trajectory planning of hypersonic vehicle, considering the constraints of no fly zone in the process, the reentry guidance scheme is designed based on the adaptive Radau pseudospectrum method;Firstly, the kinematic equations and various constraint models of the reentry section are established. Taking the minimum heat flow and trajectory oscillation in the reentry process as the optimization objective, the control and state variables are discretized by radau pseudo spectrum method, and the reentry trajectory planning problem is transformed into a nonlinear programming problem. Numerical simulation is carried out to verify the effectiveness of the method. The simulation results show that the method can plan the reentry trajectory that meets the constraints of process and no fly zone, and can provide useful support for reentry guidance of hypersonic vehicles. © 2022 IEEE.

In order to ensure the attitude stability of hypersonic morphing aircraft in the deformation process, an attitude control scheme based on incremental backstepping sliding mode is proposed for the six-degree-of-freedom model of hypersonic morphing aircraft with nonlinear, strong coupling and external disturbance. The incremental backstepping sliding mode controller is designed based on the idea of incremental nonlinear dynamic inversion, and the external disturbance is compensated by combining the extended state observer. The effectiveness of the aircraft attitude control scheme based on incremental backstepping sliding mode is verified by numerical simulation. The simulation results show that the designed incremental backstepping sliding mode controller can eliminate the chattering phenomenon and ensure the attitude control performance of hypersonic morphing vehicle during deformation. © 2022 IEEE.

By the means of analytic expression of underwater electric dipole’s coupling static magnetic field in three layers model of air, seawater and seabed, the distributing characteristics of underwater coupling static magnetic and high altitude coupling static magnetic field are analyzed. Combined with the detection level of underwater and aviation, the detection feasibility based on the corruption related magnetic field is analyzed. By comparing with static magnetic field caused by magnetic materials, it is pointed out that when degaussing technology reaches a certain level, the corruption related magnetic field may become the main impact factor of magnetic field detection. © The Institution of engineering & Technology 2023.

Modeling of cross-medium vehicles with complex shapes still requires a thorough investigation. This paper proposes a multi-method combination modeling approach to tackle such a problem. First-principle model is derived to determinate a model structure. Experiments are then set up to estimate parameters related to its rigid-body model and propulsion system. Computational fluid dynamics (CFD) is performed to calculate and identify coefficients related to surrounding fluid. Base on the model obtained, we systematically investigate the possible steady motion of the cross-medium vehicle and analyze their related performance. Results are instrumental for designing controllers for the vehicle to perform autonoumous missions. © 2023 Technical Committee on control Theory, Chinese Association of automation.

This paper presents a novel robust cooperative guidance law against high-maneuvering target based on state information obtained from networked distributed estimation. To attack the target accurately, a distributed state estimation algorithm is proposed by two steps: local filter and interaction fusion. During the interaction fusion step, the accurate state information of target can be obtained based on the local neighboring interactions. Then, the guidance law considering maneuvering target acceleration information is designed, which can be used to attack the maneuvering target accurately. Finally, a numerical simulation example for maneuvering target cooperative attack is given to validate the performance of the algorithm. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Due to the dislocation distribution of wind resources and load centers in China, large-scale wind power stations usually need long-distance transmission to connect with the load center, which leads to the weakening of the power grid strength at the access point of wind power stations and frequent short-circuit faults. In this paper, a small signal state space model of flux-controlled grid-forming DFIG grid-connected system is constructed for the continuous condition of symmetrical fault in weak grid scenario, and the oscillation mode analysis of the system is carried out. Based on the fault ride-through requirements and electromagnetic equations of wind turbines, the calculation method of the balanced operating point of DFIG during symmetrical fault duration is derived. Then, based on the system characteristic root trajectory and the participation factor matrix, the small-disturbance stability of the system under different fault conditions and converter control parameters is analyzed, and the influence of each dynamic link on the small-disturbance stability of the system is explored. Finally, the accuracy of the theoretical analysis results in this paper is verified by simulation analysis and comparison, which provides guidance for parameter optimization of DFIG during fault duration. © Beijing Paike Culture Commu.

This paper studies the problem of multi-source opportunistic signal navigation of aircraft. Firstly, the paper provides the mathematical models for five types of opportunistic signals. Furthermore, the online evaluation algorithm based on T-test is proposed for seeking the biased opportunistic signals. By disposing of the opportunistic signals causing intolerant location error, an estimated location position is obtained by trusty opportunistic signals. Finally, to handle the unknown part of flight acceleration caused by external disturbances, the extended-state Kalman filter is constructed to promote the locating accuracy. The simulation results show the effectiveness of the proposed method. © 2024 IEEE.

This paper explores the impact of the burgeoning electric vehicle (EV) presence on distribution grid operations, highlighting the challenges they present to conventional pricing strategies due to their dual role as power consumers and suppliers, coupled with their energy storage capabilities. We propose an advanced real-time pricing model for the electricity market, employing a novel distributed bilevel optimization framework. This framework distinguishes between the distribution system operator (DSO) at the upper level and the EVs at the lower level, each aiming to optimize profit margins. The optimization includes power flow constraints at the upper level to ensure efficient operation within safe system limits, while model predictive control (MPC) is used to optimize lower-level EV responses. Additionally, we provide a rigorous convergence analysis of the proposed bilevel optimization method. Detailed convergence studies and simulation results demonstrate the effectiveness and superiority of the proposed algorithm. © 2024 IEEE.
