The designed delay-free controller relies on H∞ control enhanced with integral action to account for unknown disturbance loads. The aggressiveness is based on pole clustering within preselected regions while a gain norm minimization scheme is employed to result in small attainable gains. An a posteriori computation for the maximum allowable delay bound against measurement delays reveals the need to correlate this bound to the controller’s aggressiveness. Simulation studies are used to investigate the efficiency of the suggested control scheme.","PeriodicalId":105499,"journal":{"name":"2021 European Control Conference (ECC)","volume":"328 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115385721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The robots do not know their total number and cannot distinguish between the partners, every of them determines the relative positions of neighboring objects only within a short range of visibility. A decentralized control law is presented that solves this mission, individually operates at any robot, is common for all of them and reactive, i.e., immediately converts observation data into control in a reflex-like fashion. Scenarios where the team size is increased or decreased, respectively, in the course of operation are also elaborated. The control law is justified via a mathematically rigorous global convergence result for corridors with straight parallel walls, and its performance is confirmed for more general corridors via computer simulation tests.","PeriodicalId":105499,"journal":{"name":"2021 European Control Conference (ECC)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125231363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a previous paper we presented a two-layer control approach for ecodriving which tracks an optimal speed profile resulting from the first layer under the presence of traffic in the second layer. In this paper, we extend the developed control approach to a convoy of vehicles and determine, whether it leads to safe and stable convoys and whether an increasing number of vehicles within the convoy leads to an increased fuel efficiency. Thereby, we focus on two different prediction methods of the preceding vehicle: in the first case we assume perfect knowledge of the future movement of the preceding vehicle, whereas in the second case we assume the current speed of the preceding vehicle to be constant during the prediction horizon. It is shown that the higher the number of vehicles the more fuel saving from the optimal solution can be recovered.","PeriodicalId":105499,"journal":{"name":"2021 European Control Conference (ECC)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117245192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we investigate whether the same methods could be used by an adversary to synthesize undetectable data-injection attacks on cyber-physical systems using Willems’ Fundamental Lemma. We show that if the adversary is able to upper bound the order of a linear, time-invariant system and read all its inputs and outputs, then the adversary will be able to generate undetectable attack signals in the form of covert attacks. Additionally, we provide conditions on the disclosed data set that enable the adversary to generate zero dynamics attacks. These conditions give operators insights into when enough information about the system has been revealed for an adversary to conduct an undetectable attack. Finally, the different attack strategies are verified through a numerical example.","PeriodicalId":105499,"journal":{"name":"2021 European Control Conference (ECC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124890930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quadrotors and the load in the system are modeled using the Newton-Euler approach. A Distributed Model Reference Adaptive Control with σ-modification is applied to synchronize the states of the heterogeneous and unknown quadrotors model. Quadrotors are subject to disturbances as input uncertainties and unstructured dynamic uncertainties that are overcome thanks to the σ-modification. An additional term is added to the control signal to minimize the efforts generated by the suspended load through the maintenance of the desired formation. Finally, quadrotors make use of geometric control to reach the attitude need it. The stability is demonstrated by the Lyapunov method, and the functioning of the algorithm is shown through simulation.","PeriodicalId":105499,"journal":{"name":"2021 European Control Conference (ECC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123419336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a motion control approach based on the integrated trajectory to achieve the above control objective with only one controller. First, an integration trajectory with two parts is designed for the Pendubot. We plan the first part trajectory with variable parameters, and optimize these variable parameters by applying the genetic algorithm (GA) to make all links move simultaneously from their starting states to their target states. We plan the second part trajectory to make all links remain at the target states. Then, we build the linear time-varying error system based on the integration trajectory, and design a global tracking controller by using the linear system control method to track the integration trajectory. By this way, the control objective of the Pendubot is realized. Finally, the simulations illustrate the validity and superiority of the proposed method.","PeriodicalId":105499,"journal":{"name":"2021 European Control Conference (ECC)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126619671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This framework is applied for closed-loop system identification and adaptive heating demand-response control for residential buildings. The building envelope, considered for control purposes within the context of a Model Predictive Control (MPC) strategy, is based on the simplified Resistive-Capacitive analogy. These models characterized with parametric and state uncertainty, are adapted by incorporating, on-line, learning-based Moving Horizon Estimation (MHE) for the joint state-parameter based estimation problem. Learning-based Moving Horizon Estimation, in this context, incorporates a reinforcement learning (RL) strategy. The latter entails a Q-factor parametrized value function approximation of the MHE arrival cost which is adapted (learned) on-line using a temporal difference algorithm based on the MPC control policy.","PeriodicalId":105499,"journal":{"name":"2021 European Control Conference (ECC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116462548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
