In computing this index for an open-loop system, it has always been assumed that the manipulated variables can be adjusted freely to compensate the instantaneous effects of random disturbances. To produce more practical assessments, it is necessary to impose additional constraints on these variables. Thus, the present study is aimed to derive the necessary conditions of the corresponding constrained optimization problem and also to develop the numerical algorithms needed to produce a suitable flexibility metric. Furthermore, since the maximum value of FId can be viewed as the upper bound for the closed-loop counterpart, a novel tuning strategy can also be devised to identify the PID controller parameters accordingly.","PeriodicalId":122301,"journal":{"name":"2018 SICE International Symposium on Control Systems (SICE ISCS)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124646457","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, using PVs of an inappropriate size leads to greater power losses due to variations in PV outputs and demand loads. Therefore, it is necessary to determine the optimal size of PVs. When one considers the various weather conditions and demand load profiles, the optimal PV sizing problem (OPSP) becomes a large-scale optimization that is difficult to solve. In this paper, to resolve this computational issue, we formulate the OPSP as a second-order cone programming model and propose a decomposition using the subgradient method for solving the partial Lagrangian dual problem. We implemented the proposed method on a 47-bus distribution feeder model, and the simulation results proved its viability.","PeriodicalId":122301,"journal":{"name":"2018 SICE International Symposium on Control Systems (SICE ISCS)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124658607","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}

Wind energy overview and DFIG based WT component with operating principle have been discussed appropriately in this paper. The controller design for DFIG based WT using DEO and GAO techniques along with its fitness functions are depicted. The responses of the DFIG system concerning terminal voltage, active-reactive power, and DC-Link voltage have slightly improved with DEO based controller in comparison with GAO based controller. Lastly, the obtained output is equated with a standard technique for performance enhancement of the DFIG based wind energy conversion system.","PeriodicalId":122301,"journal":{"name":"2018 SICE International Symposium on Control Systems (SICE ISCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130460661","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}

First, we apply robust loop-shaping techniques to design two controllers for the PZT stage: one has fast responses while the other is less oscillatory. Second, we apply MPC to combine the merits of these two controllers, i.e. to automatically switch the stage controllers so that the system responses can be as fast as the first controller and as smooth as the second one. Last, the designed controllers and switching mechanism are implemented and verified by simulation and experiments.

The broadcast gossip algorithm is used to reach a consensus on the scalar value of each agent in a static environment. This algorithm is suitable for the wireless multi agent system because it can reach a consensus by uniformly random broadcasting communication. In this paper, we modified the broadcast gossip algorithm to synchronize each system in a discrete time dynamic multi-agent system. The proposed algorithm reduces usage of network resources, and it has a robust property against topology change. In the simple case, we prove that this algorithm almost surely reaches a consensus on a dynamic system, and the expectation of consensus is the dynamics of average initial state. Simulation results show that the algorithm works in an oscillated system and that it can be applied to decentralized and topology-changed environment.","PeriodicalId":122301,"journal":{"name":"2018 SICE International Symposium on Control Systems (SICE ISCS)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122934299","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 particular, the LMI problem may not have any optimal solutions if the dual is not strongly feasible. This implies that the computed solutions by SDP solvers may be meaningless and useless for designing the controllers of H∞ output feedback control problems. The facial reduction is a tool to analyze and reduce such non-strongly feasible problems. We introduce the strong feasibility of the dual and facial reduction and provide the necessary and sufficient condition on the strong feasibility. Furthermore, we reveal that the condition is closely related to invariant zeros in the plant.","PeriodicalId":122301,"journal":{"name":"2018 SICE International Symposium on Control Systems (SICE ISCS)","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116128097","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 novel predictive control strategy for direct current control of two level voltage source inverter with fixed switching frequency (FSF) is proposed. The FCS-MPC-FSF controller fixes the switching frequency of output variable by applying hard constraints on number of commutations. The controller guarantees fixed number of commutations in the half of switching period in order to obtain constant switching frequency.
