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%.

Based on dSPACE real-time simulation system and LabVIEW measuring system, semi-physical simulation platform of DC motor speed-adjusting system was established. Fuzzy PID algorithm was designed based on analyzing fuzzy control and PID control for speed-adjusting system. The simulation results show that compared to standard PID algorithm, fuzzy PID algorithm improves the performance of speed-adjusting system for DC motor. On this basis, the speed-adjusting system was developed based on ATmega128 single-chip and original algorithm. Compared with simulation speed-adjusting system, there is no obvious difference on response characteristics.

In this paper, we focus on the temporary frequency support effect provided by wind turbine generators (WTGs) through the inertial response. With the implemented inertial control methods, the WTG is capable of increasing its active power output by releasing parts of the stored kinetic energy when the frequency excursion occurs. The active power can be boosted temporarily above the maximum power points, but the rotor speed deceleration follows and an active power output deficiency occurs during the restoration of rotor kinetic energy. We evaluate and compare the inertial response induced by two distinct inertial control methods using advanced simulation. In the first stage, the proposed inertial control methods are analyzed in offline simulation. Using an advanced wind turbine simulation program, FAST with TurbSim, the response of the researched wind turbine is comprehensively evaluated under turbulent wind conditions, and the impact on the turbine mechanical components are assessed. In the second stage, the inertial control is deployed on a real 600kW wind turbine - Controls Advanced Research Turbine, 3-bladed (CART3), which further verifies the inertial control through a hardware-in-the-loop (HIL) simulation. Various inertial control methods can be effectively evaluated based on the proposed two-stage simulation platform, which combines the offline simulation and real-time HIL simulation. The simulation results also provide insights in designing inertial control for WTGs.

Unmanned Aerial Vehicles (UAVs) rely on robust control algorithms to accomplish their mission. But, the classical design and testing process with its multiple stages;enormous resources, efforts and a long cycle of time are exhausted. In addition, the process has another serious drawback which is the simulation delay where the simulation period is too long especially for complex embedded systems with multi parameters. In this paper, we present an effective method for designing, evaluating and testing any multi-rotor UAV flight control system, through building up a six-degrees-of-freedom (6DoF) indoor flight environment for real-time simulation, based on MATLAB-Simulink/FPGA hardware-in-the-loop simulation (HIL). The platform aims to increase the development process pace and simplify its complexity. Also, the use of FPGA accelerates the simulation to decrease simulation lag. To demonstrate the effectiveness of the proposed testbed, an attitude estimation algorithm based on direction cosine matrix(DCM) is developed and verified on the HIL testbed.

The paper deals with the hardware in the loopsimulation (HIL) of an A.C. drive with an induction motor. This method has become indispensable in the development of complex applications. For these applications, the control system and testing software on actual devices is from a variety of reasons, unacceptable. These reasons could be equipment costs, unavailability of equipment due to its continuous use in other applications. HIL testing methods were performed using the multifunction card MF 624, which enables data connections between real electronic devices and mathematical model representing the controlled system.

Brake Assist System (BAS) requirements have been established by the Economic Commission for Europe (ECE) in R13H. Electronic Stability Control (ESC) systems typically have the value added function of Panic Brake Assist (PBA) which is defined as a Category C (sensitive to multiple criteria) Brake Assist System. PBA is designed to force the vehicle into Antilock Brake System (ABS) and to maintain ABS control when the driver spikes the brake pedal and then temporarily reduces brake pedal force before reasserting more brake pedal force. ECE test protocol requires the use of brake ramp applications to define the mean acceleration force (maF) curve which is used to define the brake pedal force where ABS activates (F ABS). After completing the brake ramp application test maneuvers and completing the data processing to define the maF curve, F ABS, upper, and F ABS, lower, the test driver then proceeds to run the panic brake assist portion of the test. A high level of skill is required for a test driver to spike the brake pedal and then reduce the brake pedal force to a level between F ABS, upper and F ABS, lower [ 1 ]. Numerous panic brake assist test runs can cause the test driver fatigue and the amount of force within specified range is difficult to vary from the high end to the low end of acceptable range. hardware in the loopsimulation that includes the physical brake system and the ability to control brake pedal force serves as another test method which can be used to eliminate need for the test driver and to more precisely control the amount of brake pedal force varying from the high end to the low end of the specified range. The methodology of using hardware in the loop (HIL) simulation to validate Category C Brake Assist System vehicle performance will be presented. HIL simulation provides additional ability to validate different versions of ESC software and calibrations. The combination of physical tests and simulations is an effective methodology to demonstrate C
