Science China(Information Sciences) 2023年第12期66卷 107-120页

作者： Junhao GUO Zhijian JI Yungang LIU Institute of Complexity Science College of AutomationQingdao University School of Control Science and Engineering Shandong University

We introduce a strategy matrix, a novel concept for ensuring controllability in game-based control systems(GBCSs). This graph-based condition is presented as an alternative to utilizing complex mathematical calculations through algebraic conditions. Moreover, to address these issues, one must first study the expression of Nash equilibrium actions. This expression yields a general formula of the game controllability matrix, which is always affected by the specific matrix(strategy matrix) comprising Nash equilibrium actions, and the matrix can not only be obtained by matrix calculation but can also be directly written through the topology, indicating the topology's specific influence on the GBCS. Finally, we build a new game-based multi-agent system and determine the controllability relationship between the system and the general system.

This paper is concerned with the dynamic coverage of multiple autonomous surface vehicles (ASVs) in the presence of static and dynamic obstacles, limited communication distance, and measurement noises. A modular control method including planning, guidance, and control is proposed. At the planning level, a swarm-based dynamic coverage strategy is developed to achieve the coverage of a given domain. Both the collision avoidance and connectivity preservation issues are solved by using artificial potential fields. At the kinematic level, novel adaptive line-of-sight guidance laws are presented based on cascade extended state observers (CESOs), such that accurate guidance signals are given by compensating for time-varying sideslip angle and suppressing measurement noises. At the kinetic level, two CESOs are developed to estimate the internal model uncertainties and external environmental disturbance, and antidisturbance kinetic control laws are designed subsequently. The proposed CESOs overcome the noises sensitivity problem of classical observers, and thus facilitate the practical implementation under measurement noises. The input-to-state stability of the closed-loop system is confirmed by the Lyapunov theory and cascade stability theory. Simulation and hardware-in-the-loop experiment results are provided to demonstrate the effectiveness of the proposed swarm-based dynamic coverage method. © 1967-2012 IEEE.

In a permanent magnet synchronous motor (PMSM) vector control system, a proportional-integral (PI) regulator is generally used for implementing closed-loop current control in the synchronous rotating coordinate system. In this algorithm, a rotating coordinate transformation is necessary for both stator current and reference voltage commands, resulting in relatively high computational complexity. With reference to the design principle of traditional PI current regulators, a reduced-order resonant current controller was developed in this study. This controller only involves a single-time rotating coordinate transformation of the reference current command, thus significantly reducing the computational workload. In addition, to facilitate the practical application, a gain-parameter analytical calculation formula applied in the design of the resonant current regulator is presented in this paper. Given accurate model parameters, the proposed resonant current regulator exhibits a dynamic performance similar to that of a traditional PI current regulator. In addition, with the presence of parameter errors, this resonant current regulator exhibits superior decoupling control performance. The effectiveness and feasibility of the proposed regulator have been verified with the simulation and experimental test results. © Beijing Paike Culture Commu. Co., Ltd. 2025.

Wireless sensor networks (WSNs) operate in complex and harshenvironments;thus, node faults are inevitable. Therefore, fault diagnosis ofthe WSNs node is essential. Affected by the harsh working environment ofWSNs and wireless data transmission, the data collected by WSNs containnoisy data, leading to unreliable data among the data features extracted duringfault diagnosis. To reduce the influence of unreliable data features on faultdiagnosis accuracy, this paper proposes a belief rule base (BRB) with a selfadaptivequality factor (BRB-SAQF) fault diagnosis model. First, the datafeatures required for WSN node fault diagnosis are extracted. Second, thequality factors of input attributes are introduced and calculated. Third, themodel inference process with an attribute quality factor is designed. Fourth,the projection covariance matrix adaptation evolution strategy (P-CMA-ES)algorithm is used to optimize the model’s initial parameters. Finally, the effectivenessof the proposed model is verified by comparing the commonly usedfault diagnosis methods for WSN nodes with the BRB method consideringstatic attribute reliability (BRB-Sr). The experimental results show that BRBSAQFcan reduce the influence of unreliable data features. The self-adaptivequality factor calculation method is more reasonable and accurate than thestatic attribute reliability method.

This paper presents a novel smart electric drive control system that enables fully wireless bidirectional communication between the controller, power supply, and sensors to facilitate real-time data sharing. The primary challenge in such systems arises from cybersecurity threats in wireless communication, requiring secure encryption and synchronization mechanisms to prevent data interception and tampering. To ensure secure transmissions, a chaos-based encryption scheme is implemented using the Liu chaotic system, formulated in the Takagi-Sugeno fuzzy (TS fuzzy) model to simplify computational complexity in synchronization control. A sliding mode control (SMC) strategy is designed to provide robust tracking performance, ensuring system stability under parameter variations and disturbances. To further enhance the control precision, a homogeneous super-twisting algorithm (HSTA)-based disturbance observer (DO) is introduced, effectively compensating for external perturbations and ensuring smooth operation. The DO also allows the use of a smaller SMC gain, which helps reduce chattering while maintaining control robustness. The Lyapunov stability theory is applied to rigorously analyze the system's stability, confirming the reliability of the proposed approach in wireless motor control applications. The system is experimentally validated on ESP32 microcontrollers, demonstrating fast response times, minimal steady-state error, and real-time secure motor control. Performance evaluation using speed response signals confirms the effectiveness of the proposed control and encryption techniques, making it suitable for industrial automation and IoT-driven motor control systems. © 2013 IEEE.

Stereo vision plays a crucial role in scientific expeditions and facility maintenance. However, fixed-baseline stereo vision lacks accuracy for long-distance measurements, while wide-baseline stereo vision encounters occlusion issues at short distances. In this study, a wide-baseline stereo matching based on multi-view geometric constraints is proposed. Initially, the camera poses of multiple wide-baseline images are estimated, followed by image rectification and depth estimation. Subsequently, the disparity searching is constrained using geometric relationships among the views, resulting in more precise depth maps. Experiments were conducted to verify the superiority of the proposed method. The results indicate that the proposed method achieves an RMSE as low as 0.15 meters, even with invalid depth points. Compared to traditional stereo vision methods, accuracy is improved by approximately 35%, and robustness is significantly enhanced. In the aircraft runway scenario, overall depth map accuracy is higher, and occluded areas are significantly reduced. © 2024 IEEE.

Permanent magnet synchronous motors (PMSM) are widely used due to their numerous benefits. It is critical to get rotor position and speed information in order to operate the motor accurately. Sensorless control techniques have emerged as a popular study area both at home and overseas. The sliding mode observer (SMO) may indirectly detect rotor position and has the benefits of easy implementation and efficient algorithms. In this study, a mathematical model for sensorless control of a PMSM is developed using SMO, vector control, and other techniques. With a surface-mounted PMSM as the study object, a mathematical model for sensorless control of PMSM is developed. PMSM's sliding mode observer model is built in the matlab/simulink environment. Experiments demonstrate that the system can track the rotor position and speed of the motor precisely and fulfill the requirements of sensorless vector control of PMSM. © 2023 IEEE.
