If an unauthorized user gains access to these sensors, a privacy leak may occur. This paper considers such a potential leak of privacy in a smart residential building, and how it may be mitigated by corrupting the measurements with additive Gaussian noise. This corruption is done in order to hide when the occupancy changes in an apartment. A lower bound on the variance of any estimator that estimates the change time is derived. The bound is then used to analyze how different model parameters affect the variance. It is shown that the signal to noise ratio and the system dynamics are the main factors that affect the bound. These results are then verified on a simulator of the KTH Live-In Lab Testbed, showing good correspondence with theoretical results.","PeriodicalId":241335,"journal":{"name":"2020 IEEE Conference on Control Technology and Applications (CCTA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131331056","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 viscosity of this magneto-rheological fluid is significantly dependent on the operating temperature; this phenomenon is particularly critical in the automotive field since the working conditions span a wide range of temperatures and, furthermore, a commercial vehicle cannot be equipped to directly measure the temperature of the fluid. This article proposes a methodology for the temperature estimation which exploits the thermodynamic relationship between the resistance of the electrical circuit of the device and the temperature of the magneto-rheological fluid.","PeriodicalId":241335,"journal":{"name":"2020 IEEE Conference on Control Technology and Applications (CCTA)","volume":"1 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116828431","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 backstepping procedure is used to synthesize a new TSM-like control law for the second and third order integrator chain. A strict Lyapunov function (LF) for the entire closed loop dynamics is given naturally by design. Further, it is shown, under a certain choice of parameters, that the LF is valid for the classical TSM control law, as well. Finite-time convergence of all states to the origin is proven for both control algorithms using this LF.

An implementation of decentralized control is in string stability of interconnected systems with applications to vehicle following. In this paper, the use of passivity formalism as a means to analyse string stability in vehicle platoons is proposed. In order to employ passivity, network theory is used to model the interconnection topology of the vehicle platoon system. A bidirectional vehicle platoon, modelled by linear dynamics under constant distance spacing, employing linear controllers is used as a case study. With this in mind, we show that any arbitrary length bidirectional platoon can be modelled as a combination of a cascade of two-port networks coupled to a one-port network. Consequently, the stability of the coupled system can be analysed using passivity theory. The work is supported by theoretical and numerical analysis.","PeriodicalId":241335,"journal":{"name":"2020 IEEE Conference on Control Technology and Applications (CCTA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130590235","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 controller mode and reference governor (CMRG) scheme for constraint and failure management in vehicle platoon systems. The CMRG is an add-on supervisor for multi-mode controlled systems that monitors and adjusts the control modes and reference inputs to enforce constraints. Through simulations we show that with CMRG, safety constraints can be enforced and sensor and/or actuator degradations/failures can be managed in vehicle platoon systems.","PeriodicalId":241335,"journal":{"name":"2020 IEEE Conference on Control Technology and Applications (CCTA)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122093513","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, the crosswind flight pattern of an AWE system is optimized in real time using recursive Gaussian process (RGP)-based adaptive control. RGP-based adaptive control fuses machine learning tools with real-time adaptive control principles. Traditionally, Gaussian process (GP) modeling requires a complete database of all the previously tested data points and their associated performance values. By utilizing a recursive update law, the RGP-based modeling used here avoids the need to maintain a complete database. The RGP-based modeling estimates a predictive mean and variance model over the control parameter design space based on instantaneous performance feedback. The candidate design space is explored by selecting points at locations of maximum uncertainty. Design points that are determined to be statistically inferior to the perceived optimum are rejected from the candidate design space. In this work, the RGP-based adaptation is applied to a lab-scale platform for experimental crosswind flight of AWE systems. Experimental crosswind flight results presented here demonstrate a 60% increase in power augmentation over traditional stationary flight.","PeriodicalId":241335,"journal":{"name":"2020 IEEE Conference on Control Technology and Applications (CCTA)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125897125","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}

Since an important point of such an application relies on the treatment of the vegetation while reducing the dissemination of hazardous chemical products, a control approach related to the detection of plants using Lidar is proposed for both controlling the robot motion and achieving spraying automation. A dedicated spraying device, allowing to (de)activate independently several nozzles has been designed and on-boarded on a mobile robot, following autonomously a detected structure (typically a row of trees). The synchronization of the sprayer and the robot with respect to the vegetation is ensured through an anticipative approach allowing to apply spraying on the vegetation pending on the robot motion.","PeriodicalId":241335,"journal":{"name":"2020 IEEE Conference on Control Technology and Applications (CCTA)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124491640","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}

To improve the shift quality, the shift time should be minimized and the impacts between the sleeve teeth and the idler gear dog teeth after speed synchronization should also be minimized. Besides creating noise, these impacts are also responsible for delaying the completion of shift and contribute to wear in the dog teeth. This paper presents a time optimal control strategy for mechanical synchronizers in a hybrid dual clutch transmission, which includes constraints such that impacts between sleeve and gear dog teeth are minimized. It is demonstrated how a mechanical synchronizer can be modeled as a double integrator system and how the standard time-optimal control solution of double integrator system must be modified such that it can be applied to mechanical synchronizers. The result is a feedback control strategy that guarantees minimum speed synchronization time and minimum noise/wear in transmission. The performance of the controller is verified by simulation.","PeriodicalId":241335,"journal":{"name":"2020 IEEE Conference on Control Technology and Applications (CCTA)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121673660","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}
