Smart devices are being utilised in industries to enhance their productivity and security. In this paper, we have developed a low-cost vehicle monitoring system using an Arduino UNO microcontroller and GSM module. The primary purpose of this research was to develop a low-cost system to start and track an automobile by integrating with GSM module. GPS and GSM modules were integrated with Arduino UNO microcontroller as a processor and controller for the whole system. An Android application was developed to communicate with the Arduino module and get the instruction from the user. The user can use the Android application to start their vehicle and track the vehicle. Locking and unlocking actions were programmed into the application for the vehicle's security purpose. The system could send the location information to the user's email address as part of the security feature. The system was successfully developed and tested in multiple real-time scenarios.

The issue of safety is very paramount in any automotive system, especially in automotive braking systems. Nowadays this safety is being somewhat overlooked as the efficient testing is not being performed on the braking systems. Nowadays it is one of the challenging tasks and keeps interest among researchers. In recent days, the researchers focused on designing the braking system which is dependent on servo vacuum booster. In this paper, we intend to aid a model to monitor the servo vacuum booster performance and also to improve the performance of the system. The virtual environment LabVIEW is the tool used to calibrate the system under test. The input stroke which is the replicant of the pedalling motion will be given through the servo motor at the rate required which is helpful to control the Programmable Logic Control (PLC). The parameters under measurement such as performance, jump in and threshold which are required for efficient braking system can be set by PLC programming in RS Logix 5000 software. Meeting the requirements while testing the servo vacuum booster will be considered as effective with no flaws and can be further processed.
安全问题在任何汽车系统中都是非常重要的,特别是在汽车制动系统中。如今,由于没有对制动系统进行有效的测试,这种安全性在某种程度上被忽视了。如今,这是一个具有挑战性的任务,也是研究人员感兴趣的课题之一。近年来,研究人员致力于设计依赖于伺服真空助力器的制动系统。在本文中,我们打算帮助一个模型来监测伺服真空助力器的性能,并改善系统的性能。虚拟环境LabVIEW是对被测系统进行标定的工具。输入行程是踏板运动的复制品,将通过伺服电机以所需的速度给出,这有助于控制可编程逻辑控制器(PLC)。在RS Logix 5000软件中,通过PLC编程,可以设置被测性能、跳入和阈值等有效制动系统所需的参数。在测试伺服真空助力器时满足要求即视为有效,无缺陷,可进一步加工。

Adaptive geodesic feedback controller design for the quadrotor 四旋翼飞行器自适应测地线反馈控制器设计
Q4 Engineering Pub Date : 2020-01-01 DOI: 10.1504/ijvas.2020.10039670

In this paper, a non-linear adaptive control method based on SO(3) for the quadrotor attitude tracking is proposed. Distinct from other control methods on Euclidean space, the controller proposed is developed on SO(3), which can avoid singularities and ambiguities. Besides, the geodesic on SO(3) is used to provide the shortest curve between the current attitude configuration and the desire attitude configuration. Then, a feedback controller based on geodesic is derived. To solve the problem that the inertial tensor of the quadrotor is unknown, an adaptive term is designed with the Lyapunov theory to estimate the inertial tensor. Thus, the almost global asymptotic stability of the quadrotor attitude tracking is achieved without the prior knowledge of the quadrotor inertia tensor. The numerical simulations are utilised to show better control performance of the adaptive geodesic feedback control method.
提出了一种基于SO(3)的四旋翼姿态跟踪非线性自适应控制方法。与其他欧氏空间上的控制方法不同,所提出的控制器是在SO(3)基础上开发的,可以避免奇异性和模糊性。此外,利用SO(3)上的测地线提供当前姿态配置与期望姿态配置之间最短的曲线。然后,推导了一种基于测地线的反馈控制器。针对四旋翼飞行器惯性张量未知的问题,利用李雅普诺夫理论设计了自适应项来估计惯性张量。因此,在不知道四旋翼惯性张量的前提下,实现了四旋翼姿态跟踪的几乎全局渐近稳定性。数值仿真结果表明,自适应测地线反馈控制方法具有较好的控制性能。

This work is intended to design the PMSM motor for a three-phase inverter and electronic gear equivalent circuit with two three-stage inverters for a three-wheel traction application. It also compares the performance parameters with the conventional gear. In recent times, Permanent Magnetic Brush Less DC (PMBLDC) and Permanent Magnetic Synchronous Motor (PMSM) motor drives have gained attention by establishing themselves as a potential alternative for conventional variable speed drives. The PMSM is widely used in many applications due to its high efficiency, torque ripple, high torque, and high performance, low and high-speed operation. This project includes inverter simulation using MATLAB simulation for speed and torque performance. By analysing the result, it can be seen that the proposed three-stage inverter-based e-gear for three-wheeler transmission offers better performance in continuous output power and torque compared to conventional gears.

The reliable performance of the autonomous mobile robot depends upon the accuracy and reliability of the sensors. Mixed pixel problem is the consequence of the effects caused by diverse intrinsic and extrinsic parameters, impulse noise, variation in incident angle and beam width that reduce the reliability of the laser scanner that leads to generate uncertainty in sensory information. The objective of this study is to modify the laser sensor model by reducing the effect of the mixed pixel problem corresponding to incident angles and intensity by a newly designed algorithm - Edge Detection Technique (EDT) for laser scanner to generate an efficient mobile robot mapping for the robust autonomous navigation. Various real-world experiments have been performed to check the reliability of the proposed EDT algorithm linked with probabilistic laser sensor model fitted on a mobile robot and the obtained results are validated through qualitative and quantitative analysis corresponding to conventional approaches.

An optimal power distribution control strategy is proposed in consideration of road gradient. Two original contributions are made to distinguish our work from current research. First, a sub-optimal State of Charge (SOC) predictive model is proposed based on Back Propagation (BP) neural network. The sampling set of the BP is obtained from the optimal results from Dynamic Programming (DP), based on a series of driving cycles in real-world and the corresponding road gradient. Second, an adaptive control method based on PID is proposed with the designed sub-optimal SOC predictive model. Specifically, the optimal shift schedule of the coupler is designed offline based on DP and is implemented into the controller in a prior fashion, to decouple the relationship between the coupler and the motors. Simulation results demonstrate that the proposed adaptive control strategy can realise optimally real-time power distribution control and is better than rule-based power distribution strategy.

Intelligent Transportation System (ITS) is the integration between communication networks, real-time control, and information technology. The system is expected to perform more complex traffic arrangements, in particular traffic management of emergency vehicles. Implementation with traffic signal pre-emption alone is not enough to give space for the emergency vehicle to cross an intersection safely, especially if the lane street has only one lane. The paper proposes a new model of traffic discharge acceleration based on queueing theory approach. In the proposed model, two performance indicators are introduced which are: speed of normal traffic in front of the emergency vehicle and travelling time of the emergency vehicle. The aim is that the emergency vehicle could reach a destination within a certain time and a constant speed. Moreover, the delay should be managed to a minimum. Linear and exponential acceleration formulas of the traffic in front of the emergency vehicle are derived and then validated. Performances of the model are tested against the models in the literature. Simulation results show the proposed model leads to better assurance that emergency vehicle is not delayed significantly. Based on the validation test, a formula has also been developed according to the proposed model.
智能交通系统(ITS)是通信网络、实时控制和信息技术的集成。预计该系统将执行更复杂的交通安排,特别是紧急车辆的交通管理。单靠交通信号优先的实施不足以为应急车辆提供安全通过交叉口的空间,特别是在车道街道只有一条车道的情况下。本文提出了一种基于排队理论的交通流量加速模型。在该模型中,引入了两个性能指标:应急车辆前方正常交通的速度和应急车辆的行驶时间。目的是使应急车辆在一定时间内以恒定速度到达目的地。此外,应该将延迟控制在最低限度。推导了应急车辆前方车辆的线性加速度公式和指数加速度公式,并进行了验证。根据文献中的模型对模型的性能进行了测试。仿真结果表明,该模型能较好地保证应急车辆不会出现明显的延误。在验证试验的基础上,根据所提出的模型推导出公式。

Aiming for improving the handling and stability performance of all-wheel-drive (AWD) vehicles, a novel torque vectoring system (TV) is proposed in this paper by distributing engine torque to the front and rear axles as well as transmitting the torque between the two rear wheels. Unlike brake-based control system such as electronic stability control (ESC), the TV system can extend the cornering stability limit without interference with the vehicle longitudinal dynamics, thus improve the vehicle stability while making the handling feel smooth and consistent. Torque vectoring control strategy is developed to allocate torque to each wheel under different driving conditions. LQR controller is designed to generate the corrective yaw moment. Simulations were firstly conducted to validate the effectiveness of this system. And then a scaled vehicle is built based on dynamic similarity of the Buckingham Pi theorem to further verify the proposed TV system. Compared with a conventional AWD vehicle with open differentials, the vehicle with the proposed TV system shows better understeer characteristics and increases the maximum level of lateral acceleration.
为了提高全轮驱动(AWD)车辆的操控性和稳定性,本文提出了一种新型的扭矩矢量控制系统(TV),该系统通过将发动机扭矩分配到前后轴,并在两个后轮之间传递扭矩。与电子稳定控制(ESC)等基于制动的控制系统不同,电视系统可以在不干扰车辆纵向动态的情况下延长转弯稳定性极限,从而提高车辆稳定性,同时使操控感觉平稳一致。转矩矢量控制策略是为了在不同的行驶条件下为每个车轮分配转矩而开发的。LQR控制器设计用于产生校正横摆力矩。首先进行了仿真验证了该系统的有效性。然后基于白金汉-皮定理的动态相似性建立了一个缩放车辆,以进一步验证所提出的电视系统。与具有开放式差速器的传统AWD车辆相比,具有所提出的TV系统的车辆显示出更好的转向不足特性,并增加了最大水平的横向加速度。
