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.

Flow-valve modelling and wheel-slip control are investigated for an automotive hydraulic braking system which uses flow valves to supply brake fluid into the wheel cylinder and on/off valves to exhaust the brake fluid. First, the model of the flow valve is built using an experiment method, since its mechanism is difficult to analyse. Furthermore, because of the intrinsic difference between the two distinct valves, a special control problem is raised concerning how to realize wheel-slip control by using a unified strategy. Considering the essential characteristics of the two valves, a hybrid control approach, which contains an ordinary, continuous, state feedback function and a supervisory logic rule, is explored. Then, one feasible solution is obtained based on Lyapunov theory in the Filippov framework, so that the convergence of the control system is strictly guaranteed in theory. The controller has few tuning parameters and it is simple to tune. Illustrative hardware-in-the-loop simulation tests are carried out. The results show that both braking efficiency and ride quality are achieved, even if there are errors in the actuator control as well as in estimation of vehicle speed.

In this paper a sliding-mode yaw moment controller and fuzzy logic wheel slip controller are proposed to enhance vehicle stability in a split-mu manoeuvre. The proposed wheel slip controller shows good performance in improving vehicle handling in a braking manoeuvre. However, when a braking manoeuvre was conducted under the split-mu condition, the yaw moment generated by the asymmetric braking forces may cause the vehicle-handling stability to deteriorate. The sliding-mode yaw moment controller was introduced to regulate the wheel slip controller to improve the vehicle-handling performance. A target slip allocation algorithm was employed to coordinate the control conflict between the anti-lock braking system and vehicle stability control. First, the proposed control system was evaluated through pure computer simulation and a hardware in-the-loop simulation system. Then an experimental test was also introduced to verify the effectiveness of the proposed control system.

The paper investigates a FPGA implementation of a simple observer aiming to improve the speed estimation behavior and to make a step towards a SOPC PMSM drive sensor-less control. The proposed approach is based on the fast processing provided by the FPGA implementation, allowing to accurately reproduce the continuous time sliding mode and to realize high performance FIR filters. Such filters allow an accurate reconstruction of the position signal by means of phase compensation, and lead to an accurate speed estimation based on the zero-crossing detection of the commutation signals. Moreover, a fast current controller is considered. The paper focuses the whole design flow and confirms the feasibility of the approach by means of hardware in the loop simulation.

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.

Real-time simulation is proving very useful in simulating complex and expensive systems using the high performance multi-processors. It has many applications in the area of testing of controllers and protection systems under real-field like situations. In this project, an effort has been made to prepare a low-cost system to carry out real-time simulation in an educational laboratory setting. The system is useful in explaining and demonstration of the dynamics and control of complex real-life systems that cannot be set up in an academic institute in any practical way. Examples of such systems include complex electric power systems, wind mills, automobiles and locomotives. The simulation system implements the system model, and its control system, in real-time. The generalized software for real-time simulation has been developed in assembly language. The testing and validation of the software and hardware tools has been accomplished.

This paper aims at designing a modeling approach for multidisciplinary integration complex product. A new ideology is introduced, that each subject is taken like a subsystem, using a nested structure as its autonomous model, and each autonomy model paralleling its counterparts. The dynamic autonomy model can be expressed in a universal format, with the Parameters Pool (PP) and the Coupling Estimate (CE) two items, reflecting parameters' alteration and the total impact of other interaction's subjects, respectively. The model of PP and CE nested in the autonomy model. All state variables are shared through the data exchange interface between each subsystems, and the coupling of interdisciplinary is implemented by PP and CE. Each subject has an enable coefficient for its working state, which can implicate single subject real-time plugging and pulling, such as systems change during hardware-in-the-loop-simulation and random noise. Also, this modeling approach can be easily used for multi-disciplinary, distributed integration platform. Two examples are provided to check its accuracy and illustrate its application.

The demand for highly accurate attitude determination sensors has increased in the last few decades. One of the best and more accurate attitude determination sensors for spacecraft is the star tracker, which determines 3-axis attitude with an accuracy of a few arc-secs. In order to achieve this high accuracy, the star tracker hardware and software can be tested on-ground with an accurate optical simulator. This work presents an open-loop and closed-loop hardware test bench to demonstrate a star tracker's functionality. The test bench consists of an optical star field simulator, a real-time simulation computer and the star tracker to be tested. A dSPACE real-time simulator is used to simulate vehicle attitude and the associated sky image is provided as input to the star tracker camera using the optical simulator. To close the simulation loop, the dSPACE simulator can respond to the star tracker measurements by changing the vehicle dynamics and thus the simulated star field image. The hardware-in-the-loop test bench was used to test the star tracker for the Hybrid Navigation Experiment for the SHEFEX-2 sounding rocket mission, which will be launched in late 2011. The test bench was first calibrated and aligned to remove errors in the simulation. End-to-end results using both the open- and the closed-loop test benches are then analyzed and discussed, which include measuring the total turn-around time and maximum vehicle rotation rate for the star tracker.

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.
