The main result also provides a guideline on how to tune the controller parameters including sample period in order to achieve the desired performance.

Under our approach, each transmitter iteratively makes an adjustment to the phase and frequency of its transmitted RF signal, by effectively implementing an algorithm to reduce the amplitude of the overall received signal to zero. We show that this algorithm can be implemented in a purely distributed fashion at each transmitter as each transmitter needs only an estimate of its own channel gain to the receiver, and a feedback signal from the receiver, that is common across all the transmitters. This is an important advantage of our approach and assures its scalability; in contrast any non-iterative approach to the nullforming problem requires that each transmitter know every other transmitter's channel gain. We prove analytically that the algorithm practically, globally converges to a null at the designated receiver. By practical convergence we mean that (i) the algorithm always converges to a stationary trajectory, (ii) that though some of these trajectories may not correspond to a null, those that do not are locally unstable, while those that do are locally stable. We also present numerical simulations to illustrate the robustness of this approach. A key novelty of this paper is that unlike its predecessors it does not assume prior frequency synchronization among the transmitters.","PeriodicalId":177490,"journal":{"name":"2013 Australian Control Conference","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130038112","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 experimental study was conducted using experimental rig complete with data acquisition and instrumentation system to collect the input-output data of flexible plate structure. This input-output data used to develop the system identification to obtain a dynamic model of flexible plate based on auto-regressive with exogenous input structure. The developed model using genetic algorithm were validated using mean squared error, one step-ahead prediction and correlation test. The fitness function of genetic algorithm is mean squared error between the measured and estimated outputs of flexible plate. The validations of developed model were presented in time domain and frequency domain. The modeling of flexible plate using genetic algorithm was used in active vibration control system design for vibration suppression on the plate structure. The performance of developed controller assessed in term of spectral attenuation obtained for resonance modes.","PeriodicalId":177490,"journal":{"name":"2013 Australian Control Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132547489","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 this paper, we compare Prediction Error Methods (PEM) and Subspace Identification Methods (SIM) for system identification of rivers. PEM can incorporate the available prior information and can accommodate the non-linearities in the model structure with ease. The models obtained by SIM are linear, and it is generally difficult to incorporate prior information, but SIM is well suited to MIMO systems such as rivers. In this paper, we simulate a few typical river scenarios and use the simulated data to obtain PEM and SIM based models. The models are compared using several measures and for the scenarios considered it is found that PEM has an edge over SIM.","PeriodicalId":177490,"journal":{"name":"2013 Australian Control Conference","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131530075","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}
