Principal Component Analysis (PCA) technique has been a popular choice for anomaly detection vowing to its capability in handling complex multiple variables. However, data extracted from chemical process plants is correlated in time due to the process dynamics, hereby making the standard PCA approach ineffective in detecting of anomalies. Also, with most industrial process data embedded with heavy noise content, the detection ability of the standard PCA strategy is greatly effected. The dynamics present in the industrial data can be incorporated using dynamic PCA modeling technique where existing PCA model is embedded with lagged variales which would aid in capturing plant dynamics. Further, the effect of measurement noise can be reduced by using wavelet based multi-scale representation of data which extracts useful information from the data in time and frequency domain simultaneously. In the current paper, a multi-scale dynamic PCA (MSDPCA)is used as the modeling frame-work while $T^{2}$ and Q statistics are used as fault detection indicators. The efficacy of the developed MSDPCA strategy is demonstrated on a bench-mark Tenneesse Eastman(TE) industrial process. The simulation results clearly shows that the MSDPCA strategy is able to detect anomalies effectively in the multi-variate dynamic TE process.","PeriodicalId":396409,"journal":{"name":"2019 Fifth Indian Control Conference (ICC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130728307","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 surveys new applications of these concepts for Q-learning: (i)The Zap Q-Learning algorithm was introduced by the authors in a NIPS 2017 paper. It is based on a variant of SNR, designed to more closely mimic its deterministic cousin. The algorithm has optimal rate of convergence under general assumptions, and showed astonishingly quick convergence in numerical examples. These algorithms are surveyed and illustrated with numerical examples. A potential difficulty in implementation of the Zap-Q-Learning algorithm is the matrix inversion required in each iteration. (ii)Remedies are proposed based on stochastic approximation variants of two general deterministic techniques: Polyak's momentum algorithms and Nesterov's acceleration technique. Provided the hyper-parameters are chosen with care, the performance of these algorithms can be comparable to the Zap algorithm, while computational complexity per iteration is far lower.","PeriodicalId":396409,"journal":{"name":"2019 Fifth Indian Control Conference (ICC)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126503699","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}

However, limited availability of land has resulted in the construction of wind farms nearby human dwellings, restricted zones and natural habitats (rivers, forests) causing a negative impact on the human health, wildlife, and the environment. Using a widely used wake model and ISO-9613-2 noise calculation method, a multi-objective optimization among three important conflicting objectives such as noise propagation, investment cost, and energy generation has been performed in this study to determine the optimal layout (numbers and positions) of wind turbines inside a wind farm. Along with this, the effects of practical constraints such as the presence of human habitats and forbidden zone inside a wind farm is also studied. A novel space decomposition based approach with repair (SDwR) strategy implemented on the basic platform of non-dominated sorting genetic algorithm (NSGA II) has been proposed to solve this problem. Pareto optimal (PO) solutions are generated that allow the decision maker to choose among various layouts by considering the permissible noise standards, cost obligations, and land availability.","PeriodicalId":396409,"journal":{"name":"2019 Fifth Indian Control Conference (ICC)","volume":"1 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127049461","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}

For certain solutions of the Riccati equation, namely so-called ‘semi-stabilizing’ solutions, the corresponding Hamiltonian matrix has two or more purely imaginary eigenvalues. In this paper we explore the relationship between existence of such imaginary eigenvalues and lossless trajectories present in the system. It is known that under suitable conditions, such imaginary eigenvalues of the corresponding Hamiltonian matrix are ‘defective’, i.e., there are insufficient corresponding independent eigenvectors for the given eigenvalue. This poses theoretical and numerical difficulties in computing the solutions of the corresponding ARE. In this paper, we formulate conditions under which such imaginary eigenvalues of the Hamiltonian matrix are non-defective. As an extreme case of non-defectiveness, we first formulate conditions under which a Hamiltonian matrix is normal, i.e. the matrix commutes with its transpose. We also provide conditions under which imaginary eigenvalues of the Hamiltonian matrix are defective.
