MECHATRONICS 2014年第8期24卷 1071-1082页

The paper concerns modern approaches towards minimising the vibration level during the high speed milling process of flat flexible details. Dynamic analysis of the milling process is performed and dynamics of non-stationary controlled system in hybrid coordinates is described. On the basis of the process dynamics, as well as on the energy performance index, suitable control law is derived in order to reduce vibration level. This control law is applied for active force generation by the piezoceramic plate actuator. The implementation issues, which concern a proposed method of vibration surveillance, are described. At first, in order to predict and obtain good efficiency of vibration surveillance within a wide range of spindle speeds, hardware-in-the-loop simulation (HILS), as a mean of mechatronic design, is applied. Subsequently, the predicted results are verified during the real cutting experiment. The latter ones evidenced good performance in the scope of vibration reduction. (C) 2014 Elsevier Ltd.

The electronics responsible for the comfort and passive safety systems in the new Opel Vectra involve a network of numerous electronic control units (ECU) from different manufacturers. Testing the ECU network is a particular challenge. Existing test methods soon come up against their limits. By using hardware-in-the-loop simulation, Opel achieves extensive test coverage and depth. Test automation considerably enhances the benefit of using the hardware-in-the-loop simulator. In future, test automation will also be extended to earlier phases of ECU development. © Springer Fachmedien Wiesbaden 2003.

Real-time simulation has become widely accepted in both academic circles and industry. The technology has been applied to many domains ranging from aerospace power systems to utility power grids. The benefits of real-time simulation are generally realized through rapid control prototyping (RCP) or hardware-in-the-loop (HIL) simulation. When HIL simulation is undertaken, the validity of the results may be challenged unless the response has been verified against real world tests. In this paper, we compare the performance of a variable speed induction motor drive against a real-time HIL simulation of the same. Real-time simulations were performed on the Opal-RT OP5600. The motor drive control algorithm was programmed on a TI TMS320F28335 DSP. Field orientated control (FOC) was implemented for motor control. The phase current waveforms for both the real and simulated drive are compared with respect to amplitude and harmonics. In addition, the dynamic response to changes in control parameters is also compared. The results show that the real-time HIL simulation results are consistent with those observed in the actual motor drive.

This paper presents a new hardware-in-the-loop simulation system for multiple fixed-wing UAVs. The proposed HILS environment makes it possible to validate the flight control algorithms under the same condition as actual flight condition. Based on the real- time kernel by Mathworks, the multi HILS system is able to simulate full 6-dof dynamic models of fixed-wing UAV in order to test the flight-ready software on the actual flight hardware. Formation control of three UAVs are examined and demonstrated as a test case to show the applicability of the multi hardware-in-the-loop simulation environment.

The engineering method for the recurrent neural network construction and identification of a mathematical model of gas turbine engines on a real data is proposed, describing the learning algorithm and the network structure. The complete process of modeling and experimental investigation - from designing of a gas turbines model in form of neural networks to its testing and debugging on the test-bed - are presented. The method was approved on a hardware-in-the-loop test-bed with a FADEC closed loop control for the start-up, ground and flight modes.

The escalating interest in renewable energy sources has spurred a demand for innovative approaches to electricity generation. Notably, marine hydrokinetic turbines have emerged as a promising solution, capable of providing cost-effective power to locations isolated from traditional grids. Among these turbines, ocean current turbines (OCTs) stand out for their ability to harness the vast energy potential stored within open ocean currents. This research paper delves into the realm of marine energy, focusing on the modeling and simulation of OCTs using a hardware-in-loop (HIL) simulation approach with the aid of an OPAL-RT environment. The experiment recreates realistic operating conditions to evaluate the turbine’s feedback performance in the real-time simulator. The research progresses to explore a grid-integrated scenario where the OCT system’s response to water flow speed changes is evaluated as a blade pitch controller is tested. Power generation profiles are recorded from the simulated grid to demonstrate grid integration capabilities. The results validate the effectiveness of the OPAL-RT platform for power HIL emulation of marine energy systems and contribute to advancing the technology required to make ocean current turbines a viable renewable energy source with the potential to sustainably meet the world’s growing power demand.

Performances of hydraulic actuation system (HAS) affect flight quality of the flight control system (FCS) directly. To reach a high performance, HAS must be tested in hardware-in-the-loop simulation (HILS) during its development stage. This paper designs the actuation controller based on high-speed digital signal processor (DSP), establishes the model of HAS with the hydraulic system simulation tool DSH plus and presents the HILS scheme, designs the interface modules of hardware and software between the HAS model and outer controller. Such factors as discretization error, delay of transmission and disturbances are taken into account in the HILS scheme, which makes the simulation results more accurate and credible. By the aid of the extended CAN module of DSP controller, it is easy to adjust the parameters in real time. Experiments show that the HILS scheme is satisfying and the design of HAS is correct.

CAN sees wide use in the aerospace industry, and is proposed as the link-layer implementation of the proposed Aeronautics Radio, Incorporated 825 protocol standard (ARINC-825). Unfortunately, CAN receives far less attention in aerospace than in the automotive domain;consequently, the aerospace security research community has been unable to assess the vulnerabilities of this protocol, due to a lack of access to data and real-time simulation infrastructure. We introduce ARINC-825TBv2, a hardware-in-the-loop link-layer simulation platform that allows aerospace security researchers to observe ARINC-encoded CAN traffic with realistic data. We present a novel, predictive attacker Gaslighter that we integrate into the testbench, and demonstrate its effectiveness. Furthermore, we implement an intrusion detection algorithm from the literature, Z-Score, and validate it using Gaslighter and realistic CAN data. We show that as the number of messages in the simulation increases, the accuracy of Z-Score drops to below that of a random predictor.
