Because of the large length (25-50 m) the mathematical model of the ladder corresponds to a distributed parameter system. The payload at the end of the ladder is modeled by a concentrated end mass (lumped parameter system). The concept of the Euler-Bernoulli beam with the special boundary conditions describing the dynamics of the concentrated mass are proposed for the mathematical model of this hybrid system. The eigenfunctions of the corresponding boundary value problem were obtained analytically. Based on the analytical form of the eigenfunctions the modal description of the plant was constructed. For active oscillation damping by feedback without a dynamical observer the ladder was equipped additionally to strain gauges with a gyroscope. The designed feedback with the sensor signals allows to damp the fundamental oscillation as well as the first dominant overtone and asymptotically stabilize the plant with respect to its equilibrium. Some numerical simulations are included and demonstrate the efficiency of the proposed approach.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133722770","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 global control system models are proposed to represent the power systems with abrupt structure changes. Multi-machine power systems are first represented by interconnected subsystems with uncertainties and nonlinearities. Then each subsystem is decomposed into four nonlinear partial systems according to switching actions of breakers under a severe disturbance. The partial feedback controllers are respectively designed for partial models and the decentralized controllers for each subsystem are obtained through membership functions. Finally, the global controller is the summation of all the control actions from every subsystem. A three-machine power system is used as an example to demonstrate the effectiveness of the proposed global control strategy for multi-machine power systems.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134427304","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}

Adaptive neural approximation techniques are employed in the design of the control law and the stability is demonstrated by means of a backstepping and Lyapunov synthesis approach. Semiglobal uniform boundedness of the closed loop signals is guaranteed. The proposed control law is able to generate the control action required for accurate positioning without exact information on the hydrodynamic coefficients of the structure and current measurements. The performance of the proposed controller is evaluated via numerical simulations. From comparative simulations, the proposed technique is found to be effective, robust and produced an improved tracking performance.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115364199","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}

Based the experimental data in tank, disturbance model caused by sea wave is presented. A recurrent neural network is used to approaching the dynamics of the ship, and the real time recurrent learning algorithm is described to train the forward model.

However, the dimensioning of induction motors is often inaccurate because, in most cases, the load behavior in the shaft is completely unknown. The proposal of this paper is to use artificial neural networks as a tool for dimensioning induction motors rather than conventional methods, which use classical identification techniques and mechanical load modeling. Since the proposed approach uses current, voltage and speed values as the only input parameters, one of its potentialities is related to the facility of hardware implementation for industrial environments and field applications. Simulation results are also presented to validate the proposed approach.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123474747","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}
