Traditionally these type of problems are solved by decomposing the solution into several sub problems: targets assignments, coordinated interception control, motion planning and motion control. In this paper we present a simultaneous solution to these problems based on the Probabilistic Navigation Function (PNF). The proposed solution considers uncertainties in the targets and obstacles locations. such that the locations and geometries of the targets and obstacles are given by Gaussian probability distributions. These probabilities are convoluted with the agents', obstacles' and targets' geometries to provide a Global Probability Navigation Function — φ. The PNF provides an analytic solution, and guarantees a simultaneous interception of all targets while limiting the risk of the agents to a given value. The complexity of the solution is linear with the number of targets and agents, and therefore is not limited to small problems. Although the solution provided by the PNF is not optimal, it provides simple and efficient solution, making it suitable for a large range of real time applications.","PeriodicalId":379025,"journal":{"name":"2017 13th IEEE International Conference on Control & Automation (ICCA)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115877529","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 model is able to predict the relevant parameters such as the internal and external temperature in each component, solution concentration, vacuum pressure and thermal power throughout the regeneration process. The approach used is simpler as detailed enthalpy at each state point can be avoided. The rate of evaporation and condensation in the regeneration system is also being focused here.

Neural networks are used to approximate the unknown nonlinear functions. A common output error transformation for different subsystems is introduced to convert the original “constrained” switched system into an equivalent “unconstrained” one. It is proved that stabilizing the “unconstrained” switched system is sufficient to achieve prescribed performance guarantees based on an improved ADT method. The controllers of subsystems are designed to guarantee prescribed bounds on the transient and steady-state performance of the output tracking errors, plus the boundedness of all other signals in the resulting closed-loop system under a class of switching signals with average dwell time.","PeriodicalId":379025,"journal":{"name":"2017 13th IEEE International Conference on Control & Automation (ICCA)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129518433","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 overcome the difficulty in computing the barycentric coordinates of a node with respect to its neighbors in 3D, a new scheme is developed for this purpose by using the fact that a congruent framework of the subnetwork consisting of the node and its neighbors has the same barycentric coordinates. A multidimensional scaling (MDS) method is used to calculate the coordinates of the congruent framework, which can provide a solution for each subnetwork with not only exact range measurements but also noisy range measurements. Thus, a linear equation related to a signed Laplacian is obtained to describe the geometric constraints of the whole network. We then show a globally convergent and linear iterative algorithm called MDS-DILOC for each node to locate itself in the three-dimensional space by solving the linear equation. Simulation is carried out to demonstrate the validity of MDS-DILOC.","PeriodicalId":379025,"journal":{"name":"2017 13th IEEE International Conference on Control & Automation (ICCA)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128567805","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 FSRA problem is formulated under a robust optimization model and an expected-value model, respectively. Then, a binary differential evolution (BDE) algorithm with new operators is proposed to solve the formulated FSRA problems.

Current approaches for multi-agent coordination which rely on continuous communication of team members, cannot be applied in the practical applications where loss of communication frequently occurs. For this problem, a role-based multi-agent model is presented for implicit coordination. The model utilizes the concept of role to decompose a mission into a set of single-agent partially observable Markov decision process (POMDPs) and a task optimal assignment. Each role-based model defined with responsibilities and rights of the role can be solved with the acceptable computational complexity. The prediction of teammates' actions is the key issue in implicit coordination, for that, an action prediction algorithm based on role-based model is proposed, which estimates the current belief state by Bayes estimation and calculates the prediction of further action by the role-based policy. After obtaining the clue of the actual action through observation, the deviation of prediction is revised by filtering the prediction set with the clue. Experimental results show the validity of the proposed approach under no communication coordination.","PeriodicalId":379025,"journal":{"name":"2017 13th IEEE International Conference on Control & Automation (ICCA)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127391547","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}
