This paper investigates the sun-tracking orientation control problem for micro-satellite with flexible solar arrays and solar array drive assembly (SADA). A control algorithm based on the dual-loop controller and sun-tracking orientation control is proposed. Initially, the SADA actuator operates in angle rate control mode, where the increment of the angle rate command is constrained via a limiter function to reduce the excitation of vibrations in the flexible solar arrays. Subsequently, a feedforward control system based on the SADA control torque is implemented to reduce the impact on the satellite attitude control. Simulation results and on-orbit flight telemetry data have validated that this strategy effectively diminishes the influence of SADA sun-tracking control on the flexible solar arrays, and the attitude stabilization control of the satellite can meet the requirements for establishing an inter-satellite laser communication link.

In Boolean networks (BNs), robustness typically refers to the system’s ability to tolerate perturbations in either the state or the rule-based structure, both of which can significantly affect network dynamics. For function perturbation of rule-based structure, most existing studies have focused on analyzing the characteristics of the perturbations or investigating the resulting dynamics through simulations. However, few works have employed external analytical tools, such as Lyapunov-based methods, to evaluate the stability of the perturbed BNs. This paper introduces a Lyapunov-based framework for analysing the robust stability of BNs under one-bit function perturbations. We establish a theoretical result showing that if a perturbed BN admits an adaptively adjustable Lyapunov function to some extent, then it is guaranteed to achieve global finite-time stability at the original equilibrium state. Finally, a numerical example is provided to illustrate the theoretical results.

This paper presents a control-theoretic survey of four representative quantum consensus algorithms, with a focus on their convergence properties and implementation feasibility. The selected algorithms—ranging from gossip-based method to measurement-based feedback method and geometric control methods—exhibit fundamentally different convergence targets, including symmetric state consensus and directional alignment of Bloch vectors. Each approach is analyzed in terms of its dynamical structure, physical requirements, and control complexity. To show their performance, numerical simulations are conducted on a 3-qubit network under a fully connected topology. The results imply the trade-offs between convergence strength, coherence preservation, and practical implementability, offering insights for the design of distributed control protocols in quantum networks.

Sequencing batch reactors (SBRs) are a type of water resource recovery facility that operate to eliminate pollutants from used water and serve as a class of critical infrastructure systems (CISs) vital in mitigating ecological degradation. However, typical operational treatment strategies rely on manual tuning and empirical adjustments, limiting process consistency, adaptability, and optimality. This work addresses these limitations and introduces an approach to modelling and operational strategy optimisation of SBR using a finite state machine (FSM) theory. The proposed framework formulates the SBR cycle as a Mealy-type FSM with cycle transitions driven by discrete input events and structured outputs that define control actions. By aligning SBR behaviour with production system principles, the model optimises input sequences and output vector parameters, targeting operational efficiency and treatment quality. This abstraction bridges the gap between process engineering and discrete event system design. Also, it facilitates modular integration with available hierarchical control architectures, supporting automated schedule generation. The advantages include formal verification potential, reduced operator dependency, and compatibility with cyber-physical CIS design requirements. However, the deployment involves process model calibration and integration with supervisory systems.

Agricultural vehicle simulation is of great importance to agricultural productivity. For example, mechanical tests for tractors could be conducted at low cost and with absolute safety by simulation. however, constructing highly precise, realistically performing dynamic models for agricultural vehicles in digital space remains a challenge. Traditional models cannot estimate large side-slip for vehicles, especially under agricultural environment. To address this issue, we combined the traditional bicycle model and a simplified tire model to develop a non-linear vehicle model in Unity digital space. Validation results showed that the proposed model can be successfully used to simulate the performance of agricultural vehicles.

Spectral imaging combined with machine learning offers a powerful approach to predicting quality parameters and classifying strawberry cultivars. This study compares the performance of Partial Least Squares (PLS) models and 3D Convolutional Neural Networks (3D-CNNs) for Total Soluble Solids (TSS, °Brix) prediction and cultivar discrimination using a dataset of 17 strawberry cultivars from two origins. For TSS prediction, the 3D-CNN model achieved superior accuracy with an R2 of 0.82 compared to 0.71 for the PLS model. For cultivar classification, the 3D-CNN model outperformed traditional approaches with an F1 score of 0.87, compared to 0.75 for the PLS model. The CNN’s ability to utilise both spatial and spectral features allowed it to capture subtle morphological differences among cultivars, which traditional models struggled to identify effectively. These findings demonstrate the superiority of deep learning models over traditional spectral methods in handling complex datasets and highlight the potential of spectral imaging and CNNs for robust quality assessment and classification in agricultural applications. Although previous studies have classified strawberry cultivars and predicted TSS, none have included as many varieties or samples (3,564) as this study. Additionally, the proposed model’s simple and replicable structure makes it especially useful for cultivar identification and easy for other researchers to adopt.

The rapid adoption of Battery Electric Vehicles (BEVs) has been driven by growing environmental awareness and advancements in energy storage technologies. However, lithium-ion cells, central to BEVs, are highly sensitive to temperature variations, requiring effective thermal management to prevent degradation, ensure safety, and optimize performance. This work presents a novel method to replicate the thermal behaviour of a battery on liquid cooling systems using standard system components. By combining a virtual battery model with a physical system, the thermal behaviour of a real battery pack is accurately reproduced. This cost-effective, safety-compliant approach enhances the development of efficient thermal management systems for BEVs. The Hardware In the Loop (HIL) platform was developed with a PXI from National Instruments and a solid-state resistance of 1 kW, while a 4 kWh battery pack prototype refrigerated with a cold plate was used for validation.

In this paper, we propose an optimization framework for the powertrain design of a two-wheel-driven electric superbike, minimizing energy consumption. Specifically, we jointly optimize the force distribution between the wheels with the gear ratio, and rear motor and battery sizing while explicitly considering vehicle dynamics and performance constraints. First, we present an energy consumption model of the vehicle, including a scalable model of the electric machine based on data from the industry, accounting for iron, copper, and mechanical losses. Then, we analyze the propulsive blending strategy to distribute the required power to the wheels while considering adherence limits. Finally, we demonstrate the effectiveness of our approach by analyzing the design of a superbike, based on regulatory driving cycles and a custom high-performance circuit by comparing the force distribution approaches. The results underline the significance of joint optimization of powertrain components and propulsive bias, achieving a reduction of up to 22.36% in energy consumption for the Sport high-performance driving cycle.

The electrification of commercial heavy-duty long-haul transport to battery electric vehicles (BEVs) is projected to be the dominant technology for future transport, but it is limited by short range and long charging time. This study develops a method to optimize transport with a single BEV to be cost-effective. It formulates an optimal plan for routing, charging, speed control, and resting periods to minimize the economic cost of operation. The plan considers constraints such as customer demand, road and charging networks, vehicle limitations, time windows, and Hours of Service regulations. It is shown that the optimal plan frequently operate near empty battery making detailed energy modeling critical, and that the strategy varies significantly depending on constraints at the final destination. The vehicle can be operated to save costs, through depot charging and energy efficient speed control, or increase its utilization, through fast charging. It is proposed that for BEVs, fleet coordination will benefit from close interaction with the day-to-day operation of single vehicles.

Polyoxymethylene dimethyl ethers (OMEx) represent a concrete solution as drop-in fuels in the context of lengthening the usage of conventional compression ignition engines, whose high efficiency and power density still make them the preferred solution for long-haul transportation. The chemical structure of these e-fuels ensures a significant reduction in soot emissions, while their enhanced combustion efficiency leads to many advantages in terms of NOx. The following study focuses on the development of a one-dimensional model for the design and optimization of control strategies with the objective of reducing the energetic drawback resulting from the introduction of OMEx in blends with Diesel. The methodology is concerned with the initial development and validation of the combustion model that is employed to simulate the performance of conventional Diesel engines. The calibration procedure and the identification of model parameters are executed using the software GT-Suite, with consideration given to different operating points across the engine map. Subsequently, an assessment of the emission reduction and optimization control strategies for Diesel/OMEx blends is conducted.
