To systematically evaluate mechanical ventilators and their automation concepts, test lungs can be used in hardware-in-the-loop (HiL) simulations. However, most test lungs do not simulate lungs with spontaneous breathing. This study presents a mechatronic test lung that consists of a bellow and a voice coil actuator. After modeling and parameter estimation, the model was used for the synthesis of a robust controller. The whole system was validated with a reference lung model and recorded measurement data of volume flow. The model identification resulted in a root-mean-square error (RMSE) of $\mathbf{0.96} \mathbf{~ m m}$. The controller achieved a maximum RMSE of 0.062 liters per second and a relative compliance error of $5.88 \%$. The test lung has the potential to enable HiL simulations of mechanical ventilation with spontaneous breathing.

A key challenge for Deep Neural Network (DNN) algorithms is their vulnerability to adversarial attacks. Inherently non-deterministic compute substrates, such as those based on Analog In-Memory Computing (AIMC), have been speculated to provide significant adversarial robustness when performing DNN inference. In this paper, we experimentally validate this conjecture for the first time on an AIMC chip based on Phase Change Memory (PCM) devices. We demonstrate higher adversarial robustness against different types of adversarial attacks when implementing an image classification network. Additional robustness is also observed when performing hardware-in-the-loop attacks, for which the attacker is assumed to have full access to the hardware. A careful study of the various noise sources indicate that a combination of stochastic noise sources (both recurrent and non-recurrent) are responsible for the adversarial robustness and that their type and magnitude disproportionately effects this property. Finally, it is demonstrated, via simulations, that when a much larger transformer network is used to implement a Natural Language Processing (NLP) task, additional robustness is still observed. © 2024, CC BY.

Temperature control is crucial for heater furnace systems in various industries, ensuring product quality, process efficiency, and safety. This abstract review temperature control methods, applications, and challenges in these systems. Precise regulation optimizes energy use, extends equipment lifespan, and maintains product consistency. Common methods include PID controllers, fuzzy logic, and model predictive control, using sensors like thermocouples. The document details PID controllers, explaining their role in industrial systems through Proportional (K P ), Integral (K I ), and Derivative (K D ) parameters. Tuning these parameters is vital, with methods like Ziegler-Nichols and Chien-Hrones-Reswick discussed. The shift from analog to digital control highlights digital systems' flexibility. hardware-In-loop (HIL) simulation for real-time testing is covered, showing its benefits in control design. Microcontroller-based systems and MATLAB for real-time simulation and control, including the Data Acquisition Toolbox, are also discussed, emphasizing graphical programming and microcontroller control.

This paper presents the design, development, and implementation of reliable and cost-effective testing equipment based on hardware-In-the-loop (HIL) for evaluating and validating DC-DC power converter control systems, focusing on educational applications. HIL simulation provides significant advantages over traditional simulation methods by enabling rapid and safe testing of converter topologies under conditions that closely resemble actual operation given good mathematical modeling of the physical system. This system supports the monitoring and control of power converters, making it highly suitable for enhancing practical learning and training in educational environments. Utilizing LabVIEW and CompactRIO hardware, the developed HIL test equipment is fully customizable to the parameters of various DC-DC circuits, facilitating the design process and providing a hands-on learning experience. The results demonstrate the reliability and effectiveness of the proposed HIL system, offering a robust and accessible solution to the challenges of existing commercial and customized HIL approaches in academic settings.

There is an increased interest on the use of UAVs for environmental research such as tracking bush fires, volcanic eruptions, chemical accidents or pollution sources. The aim of this paper is to describe the theory and results of a bio-inspired plume tracking algorithm. A method for generating sparse plumes in a virtual environment was also developed. Results indicated the ability of the algorithms to track plumes in 2D and 3D. The system has been tested with hardware in the loop (HIL) simulations and in flight using a C02 gas sensor mounted to a multi-rotor UAV. The UAV is controlled by the plume tracking algorithm running on the ground control station (GCS).

The High-thrust LOX/LH2 staged combustion cycle engines adopt variable thrust adjustment which can achieve the best thrust control and optimize the best carrying capacity. Based on the electromechanical servo-controlled engine thrust adjustment scheme, the closed-loop control flow regulation technology of the regulating valve is the core technology of the variable thrust regulation of the engine. The flow control of the regulating valve is to use the servo actuation system to adjust the cross-sectional area of the valve to control the entrance pressure of the regulating valve. According to the analysis of the nonlinear factors of the liquid flow test bench and the servo actuation system, the controller algorithm is designed on the basis of obtaining the equivalent model of the control system through the experimental data method, the effectiveness of the closed-loop control method is verified by the hardware-in-the-loop simulation platform.

When dealing with millimeter wave communications, one way to mitigate the path loss contribution involves the use of beam steering and beamforming techniques, which allow to improve the gain of the antenna system. Particularly interesting is the case of adaptive beamformers, which are able to steer the antenna radiation pattern towards the position of a given target in real-time. In this work, we propose a novel architecture for adaptive beam steering based on real-time Angle-of-Arrival (AoA) estimation. The phase shift is introduced in the Local Oscillator (LO) path thanks to a modified DDS-PLL structure. The main equations are presented, along with a validation campaign involving hardware-in-the-loop (HiL) simulations.

During the development of control strategies for permanent magnet synchronous machines (PMSM) used in wind turbines, usage of wide range of simulation allows for more detailed, more safe and less expensive development. This paper presents type of HIL simulation, where instead of using real controller and real-time simulator, two real-time simulators are used and form a co-simulation environment where vector control of PMSM is conducted. The whole process of designing and simulating is a part of model-based design (MBD). The PMSM is described and controller for vector control is derived. Created co-simulation environment with its advantages and problems is described. An experiment with different scenarios is conducted to test created co-simulation.

The rapid control prototyping(RCP) system that based on Simulink model and RTX real time system was designed. The RCP system can rapidly convert the Simulink model into the RTX real time model and realize: the automatic compilation and downloading of the Simulink model, the on-line modification of simulation parameters, real time storage of simulation data, automatic distribution simulation, configuration file administration. The simulation results, given in Fig. 8 and Table 1, show preliminarily that the RCP system designed by us is not only reliable but also gives good precision.
