The goal of the paper is to share experience with the use of hardware-in-the-loop (HIL) simulators in a control-engineering course being taught at the University of West Bohemia. The hardware simulators were introduced recently in the course curriculum aiming to get more realistic application scenarios for the students. They allow simple explanation of the concepts of model-based systems engineering in a form close to the workflow used in industrial practice. The achieved results show some significant benefits when compared to former course content, which relied on numerical simulations only. The paper presents one of the application use-cases dealing with the problem of active car suspension control. Individual phases of the control system development as done by students are explained step by step, revealing the main benefits of the hands-on experience with the physical setup.

The integration of large-scale power from renewable energy sources (RESs) via high voltage direct current (HVDC) transmission will contribute to the achievement of energy targets made by the government of several nations. This will help to reduce greenhouse gas emissions and combat climate change. With variable-speed wind turbines (VSWTs), maximum wind energy can be captured; additionally, multi-terminal HVDC grids (MTDC) can help to connect offshore wind farms (OWFs), solar farms and several countries, thus, aiding cross border trading, balancing services and RES integration. A major component of these technologies is power electronics which makes them not contribute to the system inertia. The research work presented in this thesis is aimed at investigating the effects of reduced system inertia in an ac grid rich in power electronics (i.e. HVDC and VSWTs) and proposing measures to mitigate these effects. The main contributions of this research work are: (1) investigating the effects of large-scale connection of VSWTs to the GB power system, (2) analysis of inertial contribution of VSWTs, (3) coordination of fast frequency support from MTDC grids and (4) experimental validation of frequency control schemes, including a proposed auxiliary dead-band controller (ADC). To investigate the inertial contribution from VSWTs, a test system consisting of a three-machine Great Britain (GB) power system connecting full power converterbased VSWTs was modelled. In this test system, the wind generation capacity was varied and the effect on the system frequency response was studied. It was observed that the system frequency deviation and rate of change of frequency (RoCoF) increased with the wind penetration increase. This study was followed by analysing the VSWT synthetic inertia capability. The temporary overproduction strategy which allows the release of stored kinetic energy during power imbalances was used. HVDC grids may provide fast frequency support

During virtual commissioning, the real control technology is put into operation in advance using a model-based digital twin of the production system. The growing demands on the significance of digital twins result in the need for higher model depths and model scopes of the behavior models used. However, new approaches to enhance the usable computing power in a real-time simulation are required. This paper presents a real-time co-simulation platform for virtual commissioning. The platform includes the integration of powerful technology-specific simulation solutions based on integration interfaces and a real-time co-simulation architecture based on partitioning, parallelization, synchronization and data exchange mechanisms.

The development of supervisory controllers for cyber-physical systems is a difficult and error-prone process. Supervisor synthesis enables control designers to automatically synthesize a correct-by-construction supervisor from a model of the plant in combination with a model of the control requirements. To validate the behavior of the synthesized supervisor, model simulation is commonly used. While model simulation is a powerful tool for validation, it offers only a partial analysis. Aspects related to the execution of the supervisor on the hardware and communication with subsystems, such as human machine interfaces, cannot be validated with model simulation. To bridge the gap between model simulation and realization, hardware-in-the-loop (HIL) simulation can be performed after model simulation and before implementation. For HIL simulation, the controller realization and its subsystems are connected to a model of the plant. The purpose of this paper is to propose an engineering method that combines synthesis-based engineering with HIL simulation. Models created for synthesis are refined and re-used to obtain models for model simulation and HIL simulation. To illustrate this method, a case study is presented that demonstrates its application to the Prinses Marijke complex, consisting of two waterway locks and a storm surge barrier. The necessary models have been developed and implemented in an HIL set-up.

the following contents represent the systematic approach of setting up and running the hardware-in-the-loop (HIL) simulation for an active heave compensated (AHC) draw-works as a conceptual horizon of implementing HIL for any plant whereby the model is determined. A simulation model of the draw-works is executed on a PC to simulate the AHC draw-works with a physical PLC. The PLC (ET200S) is configured with a controller architecture that regulates the motor angular displacement and velocity through actuation of the servo valves. Furthermore, a graphical user interface is developed for operation of the AHC system. The HIL test allowed tuning of the physical controller in terms of heave stabilization and positioning. The conclusion after the testing is a PLC which is ready for operation without necessitating the use a physical prototype of the process. Furhtermore, a graphical user interface (GUI) is developed for operation of the AHC system.

Power electronics system (PES) is an essential part of the fuel cell electric vehicle (FCEV), which controls the electricity from the power supplies to the electric equipment. It usually consists of the DC-DC boost converter, the motor drive inverter, and the bi-directional boost-buck converter. In this paper, an FPGA-based real-time emulator is developed for the rapid validation of the FCEV PES performance. The involved power electronics circuits are modeled and solved in a paralleled structure, which makes full advantages of the FPGA parallelism. The computational latency can be reduced to an ultra-low 5Ons after its real-time implementation on the National Instrument FlexRio NI -7975R FPGA module. The accuracy of the developed real-time emulator is proved by comparing the FPGA-based simulation results with the offline simulation tool, and the effectiveness is then validated by the real-time simulation on the NI FPGA-based real-time platform.

An autonomous car simulation system is a useful tool for autonomous car development, testing, and related research. According to the principle of an autonomous car, a distributed simulation system is designed for real-time and faster-than-real-time simulation. The hardware-in-the-loop simulation system consists of sensor layer simulation, decision and control unit, vehicle dynamics simulation, vision simulation, audio simulation, and traffic environment simulation. Data and a model with spatial and time consistency is the key to multi-field collaborative simulation. Architecture, temporal logic, and related key technologies are introduced and main data structure are represented in this paper. On the PC workstation cluster, a prototype of an autonomous car simulation system is implemented preliminarily.
