This paper describes the RT-LAB real-time simulator implementation of the Hardware-In-the-Loop simulation of a fuel cell hybrid electric vehicle system with several 10 kHz converters. The paper demonstrates the necessity to use special IGBT bridge models that implements interpolation techniques within fixed time step simulation scheme. The paper reports on the latest advances from Opal-RT to simulate this kind of system with a 10 µs sample time. HIL computational time measurement are provided as well as a model fidelity comparison made by Toyota Motor Corp. of the RT-LAB Electrical Drive Simulator versus an actual fuel cell hybrid electric vehicle. In this paper, we describe an the methodology and simulation techniques used to make the real-time simulation of a fuel-cell hybrid vehicle with DC-DC converter and several PMSM inverter drives running with 10 kHz carrier frequency. The paper is organized in the following manner. First, typical problems regarding the real-time simulation ...

In this paper we propose a general purpose hardware/software environment for hard real time simulation of dynamical systems in the context of control engineering. With this system, realistic analysis and tests can be carried out for controller algorithms characterized by time determinism with strict restrictions, multiple inputs and multiple outputs and based on robust control theory. A hard real time

UniSim is a graphic tool that can be used to develop and validate portable automation software, which fully complies with the IEC 61131-3 standard. UniSim is based on a graphical editor and on a simulation engine which allows to perform off-line validation of the automation software. Its simulation engine can also be interfaced with off-the-shelf I/O boards, in order to fast prototype automation systems by using a personal computer. Hardware-in-the-loop validation can be performed interfacing the prototype with the real plant or with an emulator. Furthermore, UniSim adopts the new XML Formats for IEC 61131-3, which provides an open interface for data exchange among different systems. Thanks to this choice the code developed with UniSim can be easily ported among different commercial platforms, increasing software reusability. Although the current release of UniSim is a work in progress version, it is already available and it can be effectively used to develop small and medium automation size projects.

This paper presents the design, simulation and real-time implementation of an aircraft longitudinal control system using a test platform constituted of a dedicated microprocessor and the X-Plane flight simulator. Initially, the concepts of longitudinal motion of a rigid body are studied. The dynamic equations of aircraft were determined using the aerodynamic stability coefficients and the longitudinal derivates. With the aircraft dynamic equation, the altitude and vertical speed continuous controllers were designed using the inner loop pitch attitude and pitch rate feedback and the forward speed controller was designed using an engine throttle model. The continuous controllers designed were discretized. Then, the digital controllers were implemented in the microprocessor. Using the X-Plane flight simulator and the algorithm implemented in the dedicated microprocessor, the digital controllers were tested and validated into the model similar to real aircraft, minimizing risks and increasing flexibility for design changes. Basically, this experimental framework employs the microprocessor running the digital flight controllers to be tested, and a PC running the X-Plane flight simulator contained the aircraft to be commanded. These resources are interconnected through data buses in order to exchange information. The interconnection between autopilot hardware and the X-Plane host is made through data communication bus based on network protocol, Uniform Datagram Protocol (UDP) available in both systems. The X-Plane has the built-in capability of transmitting flight parameters and receiving command for aircraft flight control surfaces over Ethernet using UDP. The results show that the developed system structure is appropriate to test the longitudinal controllers. Matlab environment was used to visualize the values of the updates pitch attitude, altitude, vertical and forward speed in graphics plotted in real time. It permites to observe that the designed controllers impleme- - nted in experimental framework reaches the specified requirements successfully.

Hardware-in-the-Loop (HIL) testing is proposed as a new methodology for verification and certification of marine control systems. Formalizing such testing necessitates the development of a vocabulary and set of definitions. This paper treats these issues by constructing a framework suitable for industrial HIL test applications and certification of marine systems.

Hardware in the loop (HIL) simulation enables experimental study of prototype hardware systems or control algorithms via real-time interaction between physical hardware and virtual simulations. As a result, this method is a particularly valuable tool for hybrid vehicle powertrain analysis. In the case where novel or prototype hardware is being examined, it is often necessary to scale the signals in and out of the prototype system in order to represent production-sized components. This scaling process is usually done in an ad-hoc manner. In this work, a formal method is presented that derives appropriate input/output signal conditioning to correctly scale electric vehicle components, namely the electric motor and battery subsystems.

The Air Force Electronic Warfare Evaluation Simulator (AFEWES) Infrared Countermeasures (IRCM) test facility currently has the ability to simulate a complete IRCM test environment, including IR missiles in flight, aircraft in flight, and various IR countermeasures including maneuvers, point-source flares, and lamp- and LASER-based jammer systems. The simulations of IR missiles in flight include missile seeker hardware mounted on a six degree-of-freedom flight simulation table. This paper will focus on recent developments and upgrades to the AFEWES IR capability. In particular, current developments in IR scene generation/projection and efforts to optically combining the IR image produced by a resistive array with existing foreground lamp sources.
