Fault‐tolerant control using command‐filtered adaptive back‐stepping technique: Application to hypersonic longitudinal flight dynamics

In this paper, the adaptive back‐stepping controller is investigated for a class of strict‐feedback systems using the command filter technique. Adaptive laws are designed for updating the controller parameters when both the plant parameters and actuator‐failure parameters are unknown. Furthermore, the auxiliary dynamics is developed to deal with the input constraints. Closed‐loop stability and asymptotic‐state tracking are ensured. The method is applied to the longitudinal dynamics of a generic hypersonic aircraft in the presence of actuator faults and input constraints. Based on the parameter estimation, the command‐filtered adaptive back‐stepping control is presented. Simulation results on the control‐oriented model show that the proposed approach achieves good tracking performance. Copyright © 2015 John Wiley & Sons, Ltd.

Physical and mechanical properties of a reversible adhesive for automotive applications

In this work, a hot-melt adhesive used by automotive industries for bonding plastic components has been modified with three different percentages of nanofiller (iron oxide) in order to make the adhesive electromagnetically sensitive and to perform adhesive joint separations. Fe₃O₄ particles with a weight concentration of 3%, 5% and 10% were embedded in the adhesive matrix. Single Lap Joint (SLJ) tests showed that a slight increase of the maximum load and a more ductile behaviour are obtained. The sensitivity of these modified adhesive performance to the induction heating process was studied with respect to some relevant parameters: the current (or power), the frequency of the electromagnetic induction field and the shape of the coil. Furthermore, the diameter of the hollow copper coil was modified in order to understand whether the coil temperature has an effect on the separation time. The separation time, that is an index of the time needed to reach the melt of the adhesive and the consequent SLJ separation, together with the temperature profile of the adhesives have been used to evaluate the sensitivity of these adhesives to the process parameters. The analysis on the temperature and separation time showed that the most influencing parameter is the frequency of the electromagnetic induction field. As expected, also the shape of the coil influences the separation time, in particular, the adhesive joint separated with the pancake coil showed lower values of the separation time compared to the solenoidal coils. Scanning Electron Microscope (SEM) showed that iron oxide particles tend to form small agglomerate that resulted well dispersed in the adhesive matrix. Thermogravimetric analysis (TGA) was used to verify that the separation procedure do not degrades these modified adhesives.

A distributed command governor based on graph colorability theory

In this paper, a distributed command governor (CG) strategy is introduced that, by the use of graph colorability theory, improves the scalability property and the performance of recently introduced distributed noncooperative sequential CG strategies. The latter are characterized by the fact that only 1 agent at a decision time is allowed to update its command, whereas all the others keep applying their previously computed commands. The scalability of these early CG distributed schemes and their performance are limited because the structure of the constraints is not taken into account in their implementation. Here, by exploiting the idea that agents that are not directly coupled by the constraints can simultaneously update their control actions, the agents in the network are grouped into particular subsets (turns). At each time instant, on the basis of a round‐robin policy, all agents belonging to a turn are allowed to update simultaneously their commands, whereas agents in other turns keep applying their previous commands. Then, a turn‐based distributed CG strategy is proposed and its main properties are analyzed. Graph colorability theory is used to determine the minimal number of turns and to distribute each agent in at least a turn. A novel graph colorability problem that allows one to maximize the frequency at which agents can update their commands is proposed and discussed. A final example is presented to illustrate the effectiveness of the proposed strategy.

基于非标准答案考核方式的创新型人才培养模式实践——以结构类模型创构与实现课程为例

结构类模型创构与实现课程作为一门以实践性为主的新型实践类课程,主要采用讲课、研讨、实验和上机等多种教学模式。传统考核方式侧重于考查理论知识,难以反映出学生对课程的掌握程度,尤其是实践能力的培养,而非标准答案考核方式摆脱传统的固化思维,能够较好地发挥学生的主观能动性,有利于培养学生解决复杂工程问题综合能力。因此,本课程引入了基于非标准答案的考核方式来综合评价学生的学习效果,用以培养学生的实际操作能力和创新思维。首先,系统介绍了本课程的学习目标和对毕业要求的支撑情况,论证了非标准答案考核方式在本课程中的可行性;其次,讨论分析了课程效果考核评价中需要考虑的主要因素,制定了具体的实施方案和保障措施;最后,设计了方案实施评价效果的调查问卷,对近几年数百名选课同学进行了调查统计,系统分析了课程设置、课程管理、课程资源和教师教学能力等方面的评价结果。研究表明,非标准考核方案能够很好地提高学生的学习积极性,能够科学全面评价学生对理论知识和实践能力的掌握程度,培养学生的团队协作能力与创新能力。本研究能够为其他实践类课程的课程建设和考核评价提供重要参考。
