The primary objective is to avoid collisions. The secondary objective is dealing with the quality of the collision-free trajectory, which is defined in comparison to the predefined reference trajectory. The resulted optimization problem is non-convex due to collision avoidance constraints. Two different methods to solve this non-convex program are presented, Mixed Integer Linear Programming (MILP) and convex relaxation. In MILP, using binary variables and the big-M method, the avoidance constraints can be formulated naturally. The other method is Semi-Definite Programming (SDP) relaxation. First, the optimization problem is formulated in the form of a quadratically constrained quadratic program, then it is solved using the SDP relaxation.","PeriodicalId":309111,"journal":{"name":"2014 IEEE International Symposium on Intelligent Control (ISIC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130933746","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}

We present an ultrasonic circular array sensing solution for granular presence sensing. A ceiling-mounted sensor configuration with a co-located transmitter and array receiver is considered. The transmitter sends periodic bursts of sinusoidal pulses that, upon reflection from the environment, are received at the array sensor. The echoes are processed to obtain estimates of range, azimuth and elevation angles corresponding to possible occupant movements. A Kalman filter based on a near constant velocity model is used for target tracking. The proposed array sensing solution is tested in an indoor office space with an 8-element receiver array sensor prototype.","PeriodicalId":309111,"journal":{"name":"2014 IEEE International Symposium on Intelligent Control (ISIC)","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121242088","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}

Approach proposed in this paper is in fact series of three, i.e. it starts from fault estimation, which is subsequently compensated with a robust controller. While robust controller is designed without taking into account the input constraints, compensation feasibility is proven by introducing invariant set of states, which takes into account the input constraints. If the current state do not belong to a robust invariant set, appropriate predictive control actions are performed. This appealing phenomenon makes it possible to enlarge the domain of attraction, making the proposed approach an efficient solution for the fault-tolerant control. The final part of the paper shows an illustrative example of proposed approach to the Twin-Rotor system.","PeriodicalId":309111,"journal":{"name":"2014 IEEE International Symposium on Intelligent Control (ISIC)","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116467364","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}

Unlike the classical MPC algorithms with successive model linearisation at the current operating point of the process (using the Taylor's series expansion), the best possible linear approximation of the nonlinear predicted output trajectory is repeatedly found in the discussed approach. The algorithm is computationally efficient, because it requires solving linear equations and quadratic optimisation problems.

Therefore, the main contribution of this paper consists of the development of a tolerant control scheme applied by means of a direct and viable approach. In particular, a data-driven strategy based on fuzzy logic is exploited for deriving the fault tolerant control scheme. Fuzzy theory is exploited since it is able to approximate easily unknown nonlinear models and manage uncertain data. Moreover, these fuzzy prototypes are directly identified from the wind farm measurements and lead to the straightforward design of the fault tolerant control scheme. In general, an analytic approach, where the system nonlinearity is explicitly considered, would require more complex control design methodologies. This aspect of the work, followed by the simpler solution relying on fuzzy rules, represents the key point when on-line implementations are considered for a viable application of the proposed methodology. A realistic wind farm simulator is used to validate the achieved performances of the suggested methodology.","PeriodicalId":309111,"journal":{"name":"2014 IEEE International Symposium on Intelligent Control (ISIC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129974198","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}

A special class of such engines is represented by small turbo-compressor engines suitable for propulsion of small aircraft or ground and laboratory use. Specifics of such engines demand design of specialized approaches in order to increase redundancy of their sensor/control systems, thus increasing their operational reliability and safety. The paper proposes general architectures for cost effective approaches to increase the redundancy of sensor and control systems by application of virtual sensor channels and intelligent selectors. The virtual channels are represented by neural networks fusing data from other sensors to dynamically compute the backed up parameter. Intelligent selectors form decision making elements that select the correctly operating control channel. The integration of these two elements creates an intelligent highly redundant sensor and control system suitable for small turbo-compressor engines.","PeriodicalId":309111,"journal":{"name":"2014 IEEE International Symposium on Intelligent Control (ISIC)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127257959","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}

Most current robots are limited to factories, laboratories or similar controlled settings. This contrasts with the seeming ease with which insects, animals and humans handle uncertainty, dynamic events and complexity. Assistive robots are for example being envisioned for aiding elderly and disabled persons in their homes. A key skill for these robots will be to operate in, and physically manipulate, daily life environments. However, it is unclear how to achieve this while complying with the safety and reliability requirements of such devices. Distributed Adaptive Control (DAC) is an example of a biologically inspired architecture for control and adaptation, where the lowest unit is the reflex. We here explore recent work on extending this idea to shared control of assistive robot manipulators. That is, where sensing, learning and control are distributed throughout the system, and across both user and robot. We show that such a distributed approach can reduce the need for central information processing, exact internal representations, and “global” approaches to learning in the robot. The reduced algorithmic complexity can help increase the robustness and usability of the system on real-world tasks.","PeriodicalId":309111,"journal":{"name":"2014 IEEE International Symposium on Intelligent Control (ISIC)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117229501","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}
