Abstract

In this paper, a robust controller is designed with the help of a Magnetorheological fluid (MRF) for a semi-active engine mount. To do so, an 8-DOF vehicle model is chosen in which the road roughness and engine vibration are the disturbance inputs to the system and the mass of the vehicle is taken into accounts as an uncertainty. In addition, the maximum magnitude and frequency of the force applied to the vehicle body by the actuators are limited in the ranges of 0~1500N and 0~10Hz, respectively. To validate such a design, the proposed controller is compared with a PID controller. The comparison results show that the proposed controller has a good performance while dealing with uncertainties such a way that using it leads to transmitting the engine vibration frequency less than 6%. It is also shown that the vibrations due to disturbances entering the system are effectively reduced in the system including the proposed controller.

鲁棒h -∞控制器在MRF发动机悬置中改善车辆平顺性

本文利用磁流变液(MRF)为半主动发动机悬置设计了鲁棒控制器。为此，选择了一个8自由度车辆模型，其中路面粗糙度和发动机振动是系统的干扰输入，并且考虑了车辆质量作为不确定性。此外，执行器施加在车身上的力的最大幅度和频率分别限制在0~1500N和0~10Hz范围内。为了验证这种设计，将所提出的控制器与PID控制器进行比较。对比结果表明，所设计的控制器在处理不确定性时具有良好的性能，使发动机振动频率的传递小于6%。研究还表明，在包含该控制器的系统中，由于干扰而进入系统的振动有效地减少了。

期刊介绍： The International Journal of Acoustics and Vibration (IJAV) is the refereed open-access journal of the International Institute of Acoustics and Vibration (IIAV). The IIAV is a non-profit international scientific society founded in 1995. The primary objective of the Institute is to advance the science of acoustics and vibration by creating an international organization that is responsive to the needs of scientists and engineers concerned with acoustics and vibration problems all around the world. Manuscripts of articles, technical notes and letters-to-the-editor should be submitted to the Editor-in-Chief via the on-line submission system. Authors wishing to submit an article need to log in on the IJAV website first. Users logged into the website are able to submit new articles, track the status of their articles already submitted, upload revised articles, responses and/or rebuttals to reviewers, figures, biographies, photographs, copyright transfer agreements, and send comments to the editor. Each time the status of an article submitted changes, the author will also be notified automatically by email. IIAV members (in good standing for at least six months) can publish in IJAV free of charge and their papers will be displayed on-line immediately after they have been edited and laid-out. Non-IIAV members will be required to pay a mandatory Article Processing Charge (APC) of $200 USD if the manuscript is accepted for publication after review. The APC fee allows IIAV to make your research freely available to all readers using the Open Access model. In addition, Non-IIAV members who pay an extra voluntary publication fee (EVPF) of $500 USD will be granted expedited publication in the IJAV Journal and their papers can be displayed on the Internet after acceptance. If the $200 USD (APC) publication fee is not honored, papers will not be published. Authors who do not pay the voluntary fixed fee of $500 USD will have their papers published but there may be a considerable delay. The English text of the papers must be of high quality. If the text submitted is of low quality the manuscript will be more than likely rejected. For authors whose first language is not English, we recommend having their manuscripts reviewed and edited prior to submission by a native English speaker with scientific expertise. There are many commercial editing services which can provide this service at a cost to the authors.
