The choice of the parameters of the algorithm is usually done manually. In this paper the possibility of automatic selection of parameters is investigated. These parameters are of paramount importance since they determine the final size of the network and its capacity to generalize to new situations. The number of training samples in this kind of problems is usually small. This fact has a strong influence in methods for obtaining neural models, but is rarely taken into account in the forecasting literature. The influence of the available training data is analyzed empirically.","PeriodicalId":117668,"journal":{"name":"1999 European Control Conference (ECC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127008049","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 controller guarantees a known robust performance. It is shown that in the case without time delay, the conservatism of the robust approach can be reduced by consciously choosing the nominal plant. The theory is illustrated to a first-order process with time delay but it can be extended to second order plants with more general PID-controllers.","PeriodicalId":117668,"journal":{"name":"1999 European Control Conference (ECC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130590756","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 algorithm is based on the solution of some nonlinear differential equation which is fulfilled on eigenvectors Q(t) of matrix G(t) and it is faster than classical methods for eigenproblem solution. The solution has some properties of local stability especially for the states near the minimal eigenvector. Hence it can be used in on-line application (for each t). The application of this algorithm to solution of optimal parameter identification of continuous SISO systems is also pointed.

The transfer function from disturbances to residual satisfies the prespecified constraint of H∞ norm upper bound. Simultaneously, the design freedom can be used to achieve the extreme value of the residual-to-faults sensitivity.","PeriodicalId":117668,"journal":{"name":"1999 European Control Conference (ECC)","volume":"373 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114087593","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 manipulator with its actuators (DC motors), their current feedback loops and their velocity control loops, is modelled as a \"virtual Cartesian motion device\". A linearized model of the dynamics is identified around working configurations of the manipulator. Then, based on this higher order model of the dynamics of the manipulator, 6 Generalized Predictive Controllers (GPC) are implemented on line. Simulations and experimental results show a drastic improvement in performance for a 6 DOF industrial manipulator in an eye-in-hand configuration with a high speed visual servo-loop (120 Hz) compared to standard approaches neglecting these dynamics.","PeriodicalId":117668,"journal":{"name":"1999 European Control Conference (ECC)","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124501623","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 uncertainty in the system is characterized in terms of an uncertain probability distribution on the noise input. This uncertainty is assumed to satisfy a certain relative entropy constraint. The solution to a specially parametrized risk-sensitive stochastic filtering problem is used to construct a filter for the uncertain system which guarantees a certain upper bound on the filtering error. This solution is obtained by solving a pair of algebraic Riccati equations.
