This paper presents the hardware-in-the-loop simulations of a hybrid flight control system for a light aircraft consisting of mechanical, electromechanical and digital components. The simulation was performed at a light aircraft simulation lab SimStar at Brno University of Technology. The aim was the validation and verification of the operational suitability of the flight control system's peripherals - electromechanical actuators, autopilot mode selection panel and a primary flight display. The investigated peripheral devices were connected to SimStar's network using CANaero communication protocol. The simulations were focused on the real time automatic flight control modes operational scenarios.

This paper introduces a hardwaresimulation flow that is based on the Xilinx System Generator Tool (XSG), of an architecture for solving dense linear systems, presented as a strongly coupled system, which is in turn based on Gaussian Elimination using an FPGA. A functional verification process is achieved by taking advantage of the XSG, allowing both software and hardware-in-the-loop (HIL) simulations and using the respective results achieved in Matlab as a reference model. The linear system block embedded in the XSG can handle single, double and custom data precision, following the IEEE 754 floating point standard. The current architecture improves the use of internal RAM of the selected FPGA device (Virtex-5) through a special Memory Access Unit, reducing the data access among this RAM and the different modules in the architecture. Examples of systems of six equations, which are suitable for some robotics applications, have been used for comparing the performance of the Linear System block and Matlab, the latter used as a statistical estimator, in order to validate the data results.

In this paper, a novel hybrid-type self-powered active suspension system is proposed. Proposed system differs from previous designs in several points. First of all, a hydro-electromechanical type linear actuator is specifically developed to reduce the effective inertia along suspension motion axis. Suspension control law is constructed by using a new energy-based optimal control method. In addition, power electronics module is developed and physically realized to include its dynamics in overall system performance. Beside the boundaries of analytical work, hardware-in-the-loop (HIL) simulation is performed to support the research with real world data. HIL simulation results show the energy regeneration and vibration suppression capability of proposed system.

This paper explains the FPGA implementation of a Permanent Magnet Synchronous Motor (PMSM) model using the latest JMAG-RT Finite-Element-Analysis software's real-time models: variable-DQ and Spatial Harmonic. In the variable-DQ (VDQ) model, the DQ inductances are varied according to the saturation level and a sinusoidal back-EMF is assumed. In the Spatial Harmonic (SH) model, the instantaneous magnetisation state is used to integrate the model;differential inductance and non-sinusoidal back-EMF are considered for all possible points of operation, resulting in improved precision, especially in transient states. The SH model also includes torque and current harmonics contents induced by machine slots and back-EMF spatial configurations. Both VDQ and SH models are implemented in a ML605 FPGA board running in the RT-LAB real-time simulation environment.

This paper contains a description of an adaptive protection scheme that has been implemented and demonstrated in a hardware in the loopsimulation environment using commercially available protection hardware and IEC 61850 communications. The implementation is based on an actual 11kV system which includes distributed generation and network automation. IEC 61850 communications offers several benefits for the implementation of adaptive protection, but also presents some limitations which are discussed in the paper. An alternative approach to overcome a number of the limitations is also presented.
