JOURNAL OF COMPOSITE MATERIALS 2009年第16期43卷 1695-1712页

Resin transfer molding (RTM) process has been gaining extensive attention because of its ability to produce complex structural composite parts. Researchers have made significant progress toward obtaining quality products. The preform permeability change during actual molding process brings up difficulty in achieving consistency in part quality. This article presents an adaptive RTM injection design approach in which process simulation and hardware-in-the-loop-simulation (HILS) technique are used: the whole-field preform permeability profile is provided by an in situ gas-assisted permeability measurement system and then inputted to the process simulation right before each control step during molding;an open loop control method steering the resin flow is also proposed. It is found that the HILS can be used to realize optimal injection design and flow control with accurate online permeability estimation.

MR seat suspension for vibration control of a commercial vehicle

引用

INTERNATIONAL JOURNAL OF VEHICLE DESIGN 2003年第2期31卷 202-215页

作者： Choi, SB Han, YM Inha Univ Dept Engn Mech Smart Struct & Syst Lab Inchon 402751 South Korea

This paper presents vibration control of a commercial vehicle utilizing a magnetorheological (MR) seat damper. A cylindrical type of MR seat damper is manufactured and its field-dependant damping forces are experimentally evaluated. The MR seat damper is then incorporated with a full-vehicle model in which conventional passive dampers are installed for primary and cabin suspension, respectively. After formulating the governing equations of motion of the full-vehicle model, a semi-active skyhook controller is realized by adopting a hardware-in-the-loop-simulation (HILS) methodology. Control responses such as acceleration at the driver's seat are evaluated under both bump and random road conditions.

Temperature Sensitive Controller Performance of MR Dampers

引用

JOURNAL OF INTELLIGENT MATERIAL SYSTEMS AND STRUCTURES 2009年第3期20卷 297-309页

Magnetorheological (MR) dampers can experience large temperature changes as a result of heating caused by energy dissipation, but control systems are often designed without consideration of this fact. Furthermore, due to the highly nonlinear behavior of MR dampers, many control strategies have been proposed and it is difficult to determine which is the most effective. This paper aims to address these issues through a numerical and experimental study of an MR mass isolator subject to temperature variation. A dynamic temperature dependant model of an MR damper is first developed and validated. Control system experiments are then performed using hardware-in-the-loopsimulations. Proportional, PID, gain scheduling, and on/off control strategies are found to be equally affected by temperature variation. Using simulations incorporating the temperature dependant MR damper model, it is shown that this is largely due to a change in fluid viscosity and the associated movement of the lower 'clipped optimal' control bound. This zero-volts condition determines how close any controller can perform to the ideal semiactive case, thus all types of controller are affected. In terms of relative performance, proportional and PID controllers perform equally well and outperform the on/off and gain scheduling strategies. Gain scheduling methods are superior to on/off control.

Circular Formation Guidance of Fixed-Wing UAVs Using Mesh Network

IEEE ACCESS 2022年 10卷 115295-115306页

This paper presents the guidance algorithm for the circular formation flight of multiple fixed-wing UAVs. The formation guidance law aims at reducing both the radial and the phase angle error with respect to the moving reference point located at a fixed distance from the leader UAV. To this end, the proposed guidance law generates the desired course angle and the inertial speed commands for each follower UAV. The control commands are then converted to the roll angle and the airspeed commands for the autopilot. The theoretical stability proof is rigorously analyzed via the Lyaupunov method. The performance of the proposed control law is compared with the existing vector-field formation guidance scheme via numerical simulation. After the extensive validation using the hardware-in-the-loop simulation environment which includes the mesh network communication system, the flight test are performed to demonstrate not only the performance of the proposed algorithm but also the robustness to the wind disturbance.

Modelling and Control of a Fixed Calliper-Based Electronic Wedge Brake

This paper presents a new design of an electronic fixed calliper-based wedge brake system. The movement of both sides of the brake piston is activated by a wedge block mechanism. The proposed fixed calliper-based electronic wedge brake system is a class of hydraulic-free device. The mechanism consists of two sets of wedge blocks, a ball screw drive shaft, a sliding beam and an electric motor. In this mechanism, the rotation of the shaft of the electric motor is converted into linear motion by using a ball screw drive shaft while the linear motion of the drive shaft will force the sliding beam to be displaced linearly. This will activate the wedge mechanism, which will cause the pad to be displaced tangentially to the disc brake. The movement of the pad in pressing the disc will generate clamping force and produce brake torque when the wheel rotates. In this study, the mathematical model of the system that generates the clamping force was identified. The model was based on a second order transfer function. The proposed mathematical model was then validated experimentally using a brake test rig installed with several sensors and input-output (10) device. The performance of the brake mechanism in term of rotational input of the drive shaft and clamping force produced by the brake were observed. Accordingly, a torque tracking proportional-integral-derivative (PID) control of the system was proposed and studied through simulation and experiment. Comparisons between experimental results and model responses were made. It is found that the trend between simulation results and experimental data are similar, with an acceptable level of error.

This paper presents an investigation into the performance of a fixed caliper based electronic wedge brake (FIXEWB) in a vehicle braking system. Two techniques were used as assessment methods, which are simulation via MATLAB Simulink software and experimental study through hardware-in-the-loop-simulation (HILS). In the simulation study, the vehicle braking system was simulated by using a validated quarter vehicle traction model with a validated FIXEWB model as the brake actuator. A proportional-integral-derivative controller was utilized as the brake torque control, whereas proportional-integral and proportional controllers were used as the position and speed control of the actuator, respectively. To study the effectiveness of the FIXEWB, the response of the vehicle using the FIXEWB is compared with the responses of a vehicle using a conventional hydraulic brake. A dynamic test, namely braking in the sudden braking at constant speeds of 40 and 60 km/h was then used as the testing method. The simulation results show that the usage of the FIXEWB with an appropriate control strategy produces similar behavior to that of a hydraulic brake in terms of the produced desired braking torque but with faster time response. To study the performance of the FIXEWB when implemented on a real vehicle, an experimental rig using HILS was designed and the results are analyzed using the same dynamic tests. The performance areas evaluated are vehicle body speed, wheel speed, tire longitudinal slip, and the stopping distance experienced by the vehicle. The outcomes from this study can be considered in the design optimization of an antilock braking system control in a real car in the future.

The rise of the fourth industrial revolution and the interest in autonomous production led to increased adoption of Cyber-Physical Production Systems (CPPS) in the industry. Due to the significant suitability of Multi-Agent Systems in building cyber-physical production systems compliant with the Reference Architectural Model Industry 4.0 (RAMI 4.0), more CPPS are being realized using Industrial Agents. Because of their complexity, guidelines for conducting virtual commissioning of agent-based CPPS are required. This paper proposes a novel framework for the virtual commissioning of agent-based CPPS. The framework contributions reside in incorporating both high-level and low-level control verification and validation (V&V) and employing two combined SIL and HIL approaches during the virtual commissioning of agent-based CPPS. The feasibility of the framework was demonstrated during the V&V of an agent-based CPPS on an industrial-scale laboratory robotized production cell. The framework had a significant impact on reducing the cost and efforts of the agent-based CPPS virtual commissioning.
