The focus of this paper is on the issue of disturbance rejection in leader-follower multi-agent systems based on a reduced-order observer. By combining with the practical, unknown perturbations are considered to be generated by the external system by designing a reduced-order estimation observer to obtain an estimate of the disturbances in the followers. Second, a control protocol is designed for each follower based on the obtained estimates. The design method of the reduced-order observer used in this paper simplifies the state equations of the reduced-order observer by reducing the order compared to the full-order observer, which is simpler to compute and can also effectively suppress the effects of disturbances. Finally, the feasibility of this scheme is verified by numerical examples. © 2023 IEEE.

The State of Health (SOH) of lithium-ion batteries is a critical parameter that mirrors the performance of their health monitoring systems. To achieve accurate prediction of SOH, we propose a novel prediction model. The model combines the advantages of variational mode decomposition (VMD) and transit search optimization- least squares support vector machine (TSOA-LSSVM). The constant-current charging time (CCCT), constant-current discharging time (CCDT), and Constant voltage charging time(CVCT) with Internal resistance(IR) are extracted as health indicators (HIs), and the correlations between HIs and SOH are evaluated by using Spearman correlation coefficient (spearman) respectively. With the VMD method, the most correlated HI is decomposed into multiple intrinsic modal functions (IMFs), and each IMF is fitted by the LSSVM. TSOA is used to obtain the most appropriate hyperparameters. The efficacy of the newly developed VMD-TSOA-LSSVM model is assessed by utilizing battery aging data sourced from the Center for Advanced Life Cycle engineering (CALCE). Its performance is then compared to that of the solo LSSVM, the VMD-LSSVM, and the VMD-TSOA-SVM methods. The laboratory outcomes demonstrate that the VMD-TSOA-LSSVM model outperforms other models in prediction and has better robustness and generalization ability. © 2024 IEEE.

In this paper, the network models of coupled delayed memristive neural networks (CDMNNs) without and with delayed coupling are studied respectively. Firstly, according to the definitions of ψ-type stability and ψ -type function, the notion of general decay anti-synchronization (GDAS) is introduced. Secondly, by constructing Lyapunov functional, designing controller and using inequality techniques, the corresponding sufficient conditions that reaching GDAS for CDMNNs with and without delayed coupling are deduced. Thirdly, the validity of the results is proved by proper numerical simulation. © 2023 IEEE.

This paper investigates the path-guided distributed formation control of networked autonomous surface vehicles(ASVs) subject to model uncertainties and environmental disturbances. A safety-certified path-guided coordinated control method is proposed for multiple ASVs to achieve a distributed formation in obstacle environments. Specifically, a neural predictor with a high-order tuner is presented to approximate unknown nonlinearities with accelerated learning performance. Subsequently, control Lyapunov functions(CLFs) and control barrier functions(CBFs) are constructed for mapping stability constraints and safety constraints on states to control inputs. A quadratic optimization problem is constructed with the norm of control inputs as the objective function, CLFs and CBFs as constraints. Neurodynamic optimization is used to deal with the quadratic programming problem and generate the optimal kinetic control signals, thereby attaining the desired safe formation. Unlike the high-order CBF, a CBF backstepping method is proposed to establish safety constraints such that repeated time derivatives of system nonlinearities can be avoided. The multi-ASVs system is ensured to be input-to-state safe irrespective of high-order relative degree. Through the Lyapunov theory, the multi-ASVs system is proven to be input-to-state stable. Finally, simulation results are presented to validate the efficacy of the presented safety-certified distributed formation control for networked ASVs.

The main focus of this research is on improving the performance of dynamic systems with actuator non-linearities and time-varying disturbances. To this end, using the concept of finite-time stability, a novel observer is presented to estimate the disturbances in systems with input non-linearities. Then, introducing an innovative sliding manifold, a robust observer-based technique is derived to guarantee the finite-time stability of the sliding surface. Hence, the closed-loop system would be stable in the presence of hard non-linearities and time-varying disturbances. The performance of the proposed approach was assessed in using a simulation study of two numerical examples. The obtained results and comparison with a conventional method confirmed the benefits of the suggested approach. © 2022 The Authors.

Given the widespread use of lithium-ion batteries, accurately forecasting their State of Health (SOH) is crucial for ensuring the secure and reliable operation of equipment. The local capacity regeneration during battery degradation can undermine prediction accuracy. This research introduces an MDT-FOA+TiDE approach for predicting SOH in lithium-ion batteries using multidimensional time series data. Initially, capacity and various feature data from the degradation process were collected and health indicators were derived. Features with high correlation to capacity were integrated into multidimensional time series. Subsequently, the Time-series Dense Encoder (TiDE) model was employed for training and prediction, while the Fox Optimization Algorithm (FOA) was used for model optimization. Experimental results using the NASA dataset demonstrate that the proposed approach outperforms SVR and LSTM models that utilize univariate data and MDT-TiDE model without FOA optimization. © 2024 IEEE.

In complex marine environments, it is difficult to obtain important parameters such as the number, location, and shape of oil spill surfaces;multiple oil spill surfaces may overlap and merge, which makes the accurate tracking of multiple oil spill surfaces even more difficult. To address the aforementioned issues, proposed a multi-spill surface target tracking method based on the oil particle-random point pattern. Firstly, the oil spill surface is represented by an oil particle model. Then, a random point pattern algorithm is introduced to cluster the oil spill surface. Finally, the GLMB filtering method is utilized to track the centroid trajectory of the oil spill surface, and its shape and concentration information is recorded at the same time. Simulation experiments show the effectiveness of the proposed algorithm. © 2023 IEEE.

Snake robots, a category of bionic robots, have garnered significant interest due to their capacity to adapt autonomously to complex unstructured environments. This is achieved through the flexibility and versatility of their bodies and gaits, as well as the coordinated movements of their bodies. However, in unknown or complex environments with obstacles, snake robots are unable to plan their next locomotor actions based solely on the sensory information obtained from the camera they carry. The incorporation of haptics is anticipated to facilitate the snake robot's perception of the interaction between its body and the external environment, thereby enabling more precise and effective guidance for efficient movement. This paper presents the design of a flexible tactile sensor based on the principle of photoconductivity, which has been developed to enable a snake robot to perceive and interact with its environment through tactile sensing. The sensor is intended to enhance the robot's autonomous movement capabilities in complex environments where visual recognition or human observation alone is insufficient. © 2024 IEEE.

This chapter presents the study carried out to discover uncertain parameters in a model of a doubly-fed induction generator (DFIG)-based wind energy conversion system (WECS) and to investigate their effects on WECS plant while harvesting energy from wind at varying speeds. This is carried out by analytically formulating the steady-state models of a DFIG-based WECS and computing the parameters of these models at different wind speeds that drive wind turbines at rotor speed from sub-synchronous to super-synchronous. The main uncertain parameters in this system are the mutual reactances between stator and rotor windings, and the reactance of rotor winding. These variations happen due to the varying wind speed. The effect of parametric uncertainties on the steady-state performances of DFIG-based WECS is examined. The results depicted that the steady-state performances of DFIG-based WECS are influenced by uncertain phenomena. Typically a 0.5% change in mutual reactances caused up to 10 kW change in the generator output power. Mainly, it causes instability in the performances of the DFIG-based WECS and slightly reduces overall efficiency at a higher value of the wind speed. © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG.
