To simulate constraint elements of mechanical systems like joints or bearings in their environment a hardware-in-the-loop (HiL) simulator is proposed. It couples a real joint with a numerical simulation of its environment by means of an actuator system and sensors. The actual application standing behind this investigation is HiL testing of hip endoprostheses with respect to their dislocation behavior. HiL simulations allow the analysis of real system components in a virtual environment controlled by a computer and are thereby particularly advantageous if test conditions in the real environment of the system component are either too complex or impossible to apply like in vivo investigations of dislocation scenarios. As a preliminary research two fundamental variants for the coupling between the real joint and the simulation of the environment are discussed and experimentally demonstrated.

The design of a hardware-in-the-loop simulation platform for the service performance testing of industrial robot servo systems was discussed. An offline and online workload simulation mechanism was proposed to apply in the platform. Some experimental results indicated that the workload simulation mechanism can realize the general workload output and ensure the real-time performance of the output. And the service performance testing of a 6-DOF industrial robot was provided, demonstrating the effectiveness of the hardware-in-the-loop simulation platform.

To make rigorous evaluation before implementation on actual equipments with low cost and high flexibility, the hardware-in-The-loop (HIL) real-time simulation of Permanent Magnet Synchronous Machine (PMSM) drives based on Field Programmable Gate Array (FPGA) was proposed in this paper. The PMSM and inverter were modeled and then embed into a single FPGA chip, which was connected to a actual DSP-controller through I/O interface circuits to make the HIL simulator. The real-time simulation was carried on the HIL simulator with the 50MHz clock, and the experimental total delay (response time) was 4.14μs. The experimental results of the proposed HIL simulator (actual DSP-controller + FPGA-based HIL simulation models) were compared with another platform, which included a actual DSP-controller, actual inverter and a actual PMSM. The maximum difference between those two platforms was below 1.45%.
Exploration of outer space has never stopped, and space docking is an important space technology. hardware-in-the-loop (HIL) simulation is a good approach to perform the ground test for the docking device. However, th...
