Firstly, the network control system is modeled using Takagi-Sugeno fuzzy rules. Meanwhile, the defective communication links with packets loss in both channels, from the sensor to the controller and from the controller to the actuator, are modeled by stochastic binary switching variables with known probability distributions. Then, by using linear matrix inequality method, the sufficient conditions for the existence of the fuzzy controller, the fuzzy robust controller are designed to guarantee the stability of the closed-loop system.","PeriodicalId":429208,"journal":{"name":"2017 Australian and New Zealand Control Conference (ANZCC)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122326117","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}

Even in smaller telescopes such as the EOS 1.8m telescope at Mt Stromlo Observatory, Canberra, closed-loop control systems are required to operate in the order of kHz with hundreds, if not thousands of internal states. Typical Matrix Vector Multiply (MVM) control calculations grow in computational demand to the order of N2. The Distributed Kalman Filter (DKF) proposed by Massioni et al [1] when being performed in the Fourier Domain allows the computational cost to scale as N log N [2], provided that the state space model is shift-invariant in its basis. In this paper we develop a procedure for the modeling and identification of a dynamic shift-invariant turbulence model that does not require prior knowledge of the layers velocities and turbulence profile, while satisfying the structural requirements of the DKF.","PeriodicalId":429208,"journal":{"name":"2017 Australian and New Zealand Control Conference (ANZCC)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123129412","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 two-layer control strategy is adopted, while the upper layer is a cooperative control to organize all the PV units to work cooperatively with given power ratio and the lower layer is a tracking control for a single PV unit. The information communication between PV units is realized through the ring communication structure applied in the upper layer. By using a mixed sensitivity approach, the controller for each single PV unit has strong robustness. The effectiveness of the proposed method is demonstrated by simulation in Matlab.","PeriodicalId":429208,"journal":{"name":"2017 Australian and New Zealand Control Conference (ANZCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130328391","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}

When a vehicle is moving along the road it is exposed to vibrations in multiple axes and directions. Vehicle behavior is extensively investigated in reference to road imperfections that could be expressed as single step disruptions, like remote bumps on the road. A simulation model, previously designed, was already used to investigate vehicle behavior, when riding over the step inputs. This model is further upgraded and now can perform simulations of the scenarios when vehicle is subjected to continuous imperfections on the road, like long runs of the gravel road in the country areas. Vehicle behavior is analyzed for few, common, speed levels in such scenarios. We can achieve lover amplitudes of pitch vibrations driving with the certain speed, but far the best outcome is obtained when active suspension is applied.","PeriodicalId":429208,"journal":{"name":"2017 Australian and New Zealand Control Conference (ANZCC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122409868","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 controller is designed to be robust against actuator faults as well as noise, while keeping the wind turbine generating as much power as possible. The wind speed variation is considered as an external disturbance, and an adaptive radial basis function neural network is utilized to estimate aerodynamic torque. Estimation of a fault size and establishment of a desired trajectory are adopted in the design. Using the proposed method, the reliability of wind power generation is increased so as to track the optimum power point under faulty conditions, close to the fault free case. Uniformly ultimately boundedness of the closed-loop system is achieved using Lyapunov synthesis. The designed controller is verified via numerical simulations, showing comparison with an industrial reference controller, using predefined criteria.","PeriodicalId":429208,"journal":{"name":"2017 Australian and New Zealand Control Conference (ANZCC)","volume":"175 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131786461","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 fuzzy logic based control approach to smooth the power output of the collocated wind and photovoltaic generation system. A first order filter is modified with a fuzzy logic controller which regulates the battery power, the state of charge and pitch angle for smoothing of the output power. The controller adjusts the time constant of the filter based on the state of charge of battery and pitch angle of wind generation system by considering the battery power. The effectiveness of the proposed approach is analyzed by considering the different values of the state of charge.","PeriodicalId":429208,"journal":{"name":"2017 Australian and New Zealand Control Conference (ANZCC)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125353220","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 focuses on a passive localization method. The presented method uses passive, synchronised and localized radio sensors to take the time-difference-of-arrival (TDoA) measurements for different pairs of sensors, with reference to an unknown target-emitted radio signal. The localization method is simple, memory efficient and robust. Importantly, the proposed measurement-wise recursive method is suitable for real-time application of time-critical robotic systems. The method is easily transferable to other problems that involve finding the intersection point of multiple (curved) lines in the presence of noise. Monte Carlo simulations and experimental tests on real data were conducted to evaluate the performance of our localization method. The results obtained compare favourably to other well-known methods.","PeriodicalId":429208,"journal":{"name":"2017 Australian and New Zealand Control Conference (ANZCC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116950319","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}
