Simon Abourida, Abstract
Avionics, navigation systems, flight controls and power units are becoming increasingly sophisticated within aerospace and defense systems (airplanes, UAVs, missiles…).
Hardware-in-the-loop simulation is a cost-effective method for testing the complex, flight critical hardware before it is used in the real world. This paper discusses Real-Time and Hardware-In-The Loop simulation used for the design and testing of these systems. The paper describes the general design and architecture of an advanced real-time, distributed processing, PC- and FPGA-based simulator platform (RT-LAB), and gives several examples of the uses and applications of this platform for the design, tuning and testing of aeronautic systems.

Presented in this paper are the results of closed-loop control experiments using a virtual permanent magnet synchronous motor (PMSM) drive implemented on a fieldprogrammable gate array (FPGA) card connected to an external controller. The FPGA-based PMSM motor drive is implemented on an eDRIVEsim simulator, based on the RT-LAB platform. The eDRIVEsim simulator implements 2 types of motor drive models, Park (d-q) and Finite Element Analysis (FEA), on an FPGA card of the simulator.
The FPGA-based motor model is designed with Xilinx System Generator (XSG) blockset with no HDL hand coding. Both motor models compute motor currents using a phase-domain algorithm solver that can take into account the instantaneous variation of
inductance and non-sinusoidal induced voltage. The FEA-type model uses inductance and Back-EMF profiles computed with JMAG-RT. The d-q model uses sinusoidal induced Back-EMF voltage and phase inductance values computed from Ld and Lq using the well-known Park transformation. A 3-phase IGBT inverter implemented in the FPGA chip drives the PMSM machine.
The PWM controller is designed using Rapid Control Prototyping (RCP) methodology based on Simulink. It is implemented on an separate RT-LAB system using standard Opal-RT FPGA-based I/O cards for Analog Input capture and PWM generation. The paper presents results from the closed-loop control of the PMSM drive in both current control and speed control modes and discusses the advantages of using such a virtual test bench for motor drives.

This paper presents the RT-LAB Electrical Drive Simulator technology along with practical applications. The RT-LAB simulation software enables the parallel simulation of an electrical circuit on clusters of PC running QNX or RT-Linux operating systems at sample time below 10 µs. Using standard Simulink models including SimPowerSystems models, RT-LAB build computation and communication tasks necessary to effectively make parallel simulation of electrical systems with low cost off-the-shelf PC technology. To accommodate the high bandwidth of electrical systems, the RT-LAB Electrical Drive Simulator comes with special Simulink-based modeling tools, namely ARTEMIS and RT-EVENTS that permits real-time simulation of electrical systems at practical time step of 10 µs but with sub-µs equivalent precision through the use of interpolation techniques.
