In this paper, the relatively new smooth variable structure filter (SVSF) is used for the training of a nonlinear multilayered feed forward network. The SVSF is a recursive sliding mode parameter and state estimator that has a predictor-corrector form. Using a switching gain, a corrective term is calculated to force the network weights to converge to within a neighbourhood of the optimal weight values. SVSF-based trained neural networks are used to classify engine faults on the basis of vibration data. Two faults are induced in a four-stroke, eight-cylinder engine. Furthermore, a comparative study between the popular back propagation method, the extended Kalman filter (EKF), and the SVSF is presented. Experimental results indicate that the SVSF is comparable with the EKF, and both methods outperform back propagation.","PeriodicalId":208713,"journal":{"name":"2011 IEEE International Conference on Control Applications (CCA)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122954617","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}

Side slip angle and slip ratio is measured by caster type odometers which are comprised of directional sensors and travel distance sensors. The odometer system has redundant four encoders to measure three dimensional velocities: planar two dimensional and rotational movements. We reduce the error between target velocity and actual velocity by feedback control based on both tire slip angle and slip ratio. This method can improve stability and accuracy of movement of vehicles. The experimental vehicle is an omnidirectional vehicle which has legs comprised of three joints. Experimental results of circular trajectory running show effectiveness of the proposed control method.","PeriodicalId":208713,"journal":{"name":"2011 IEEE International Conference on Control Applications (CCA)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114358759","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 characteristics is how long past of tracking error information is utilized to decide the operation command. This evaluation is achieved by a novel human model with multiple neural networks which have different time series of input signals. Then, by the prediction errors from the neural networks, which time series is dominant to decide operation command can be estimated. In this paper, target tracking tasks in 2D CG environment are experimented. A main goal of the task is to operate the mobile target by joystick operation to keep approaching a reference target behaving randomly. Furthermore, effects of subliminal input filtering by predicted operation input are discussed. Finally, by analysis for distribution the neural networks prediction errors, the operator's skill is evaluated and verify the technique with conventional average of tracking errors during the task.","PeriodicalId":208713,"journal":{"name":"2011 IEEE International Conference on Control Applications (CCA)","volume":"11 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120870594","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}

These unicellular photosynthetic microorganisms fix carbon dioxide efficiently, converting it into biomass and high-value compounds. One of the control system challenges is to maximize carbon dioxide consumption by maintaining the cellular concentration to an optimal value in the exponential phase. In this paper, we propose a software sensor for the biomass concentration of Chlorella vulgaris culture in a continuous photobioreactor with uncertain model parameters. From Total Inorganic Carbon measurements, the interval observer can provide a guaranteed upper and lower bound for the cellular concentration using the available interval of the uncertain initial condition, model parameters and measurements. Numerical simulations and experimental validation are included to illustrate the performance of the proposed estimation strategy.","PeriodicalId":208713,"journal":{"name":"2011 IEEE International Conference on Control Applications (CCA)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114099154","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}

Discrete and continuous Homography Matrices are used to recover robot pose and velocity from image sequences of tracked feature points. The camera's limited field of view is addressed by chaining vision-based motion estimates. As feature points leave the field of view, new features are acquired and tracked. When a new set of points is needed, the motion estimate is reinitialized and chained to the previous state estimate. An extended Kalman filter fuses measurements from the robot's wheel encoders with those from visual and inertial measurement systems. Time varying matrices in the extended Kalman filter compensate for known changes in sensor accuracy, including periods when visual features cannot be reliably tracked. Experiments are performed to validate the approach.","PeriodicalId":208713,"journal":{"name":"2011 IEEE International Conference on Control Applications (CCA)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126835975","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 simple and effective method to do the image processing, catching this dynamic movement in real-time and controlling the overhead crane. Visual tracking based on color histograms will compare the color in a model image with the color in image sequences to track the dynamic object. Once it tracked, the sensing data will be sent to the adaptive fuzzy sliding mode controller (AFSMC) to control the overhead cranes. The merits of it include the robustness and model free properties of the sliding mode and fuzzy logic controllers; adaptable slopes of the sliding surface are also presented to enhance the control results.","PeriodicalId":208713,"journal":{"name":"2011 IEEE International Conference on Control Applications (CCA)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126200082","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}
