This paper presents a new development in the field of design process and testing of motor drives, for hardware-in-the-loop (HIL) applications. It consists of implementing the Finite Element (FE) Method applied to electric motors on a real-time simulator;coupled with circuit simulation, this enables accurate real-time simulation of the complete motor drive, including the inverter and the motor. The paper describes the integration of FE-based motor model generated by JMAG (R) software, with the high-end real-time RT-LAB (R) simulator. The complete solution consists of combining accurate FE-based motor model, with inverter model, including important switching parameters, all constructed in the Simulink (R) environment, and simulated on PC-based RT-LAB simulation platform, using ultra-fast processors and FPGA-based inputs/outputs (I/O) boards. By connecting the real-time simulator to an external controller under test, this allows high fidelity HIL simulation of motor drives and enables the design engineers to test the system and the controller with a very accurate, FE-based motor model running in real-time.

The inherent non-idealities, especially the time delay, in the interface of a PHIL simulation may lead to large simulation errors or even instabilities. Therefore, it is extremely important to have an effective way to evaluate the simulation accuracy in order to justify the reliability of a PHIL experiment. A generalized metric defining the error functions from two types of PHIL interface perturbations is proposed in this paper. Two simulation examples are performed to show the validity of the proposed method.

This paper presents a Field Programmable Gate Array (FPGA) based real-time digital simulator for power electronic apparatus based on an realistic device-level behavioral model. A 3-level 12-pulse Voltage Source Converter (VSC) fed induction machine drive is implemented on the FPGA. The VSC model is computed at a fixed time-step of 12.5ns allowing an realistic representation of the IGBT nonlinear switching characteristics and power losses. The simulator also models a squirrel-cage induction machine, a direct field-oriented control system, and a pulse-width modulator to achieve the real-time simulation of the complete drive system. All the models have been implemented using VHDL. Real-time simulation results have been validated using measured device-level IGBT characteristics.

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.

This paper details the design and development of a robotic hardware-in-the-loop simulation platform that can be used for rapid-prototyping industrial manipulators. The architecture of the proposed platform has been presented in [1]. Potential benefits of such a platform include allowing concurrent development of hardware and control system components and providing a reusable platform for reconfigurable manipulators through a generic and modular structure. Some preliminary tests on the platform have also been discussed in the paper.
