Parameter-varying in the MPC context means that a prediction model with non-constant, parameter-varying system matrices is employed. In the investigated scenario, the displacement of a car on an icy road under a side wind gust shall be mitigated. In order to explore a possible reduction of online computations and the inherent degradation of control performance, the nonlinear model of the lateral dynamics is approximated in various ways. A comparison between controllers using prediction models varying from the full nonlinear model, as an indication for the maximal achievable performance, to a linear model has been performed. Particular emphasis was put on the hybrid parameter-varying prediction model, to investigate their potential in terms of computational effort and control performance.","PeriodicalId":407048,"journal":{"name":"2007 European Control Conference (ECC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130843076","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 desired performance is attained by putting frequency bounds on the sensitivity and the complementary sensitivity functions of the system in order to guarantee appropriate input tracking and sensor noise attenuation. The algorithm makes use of Neimark's D-partition results on robust stability and extends the results to the case of robust performance. Explicit formulae are provided for performance measures, need to be minimized in a frequency range to compute the robust performance margin. The algorithm is then used in a controller synthesis procedure to design robust controllers in order to meet both stability and performance requirements. The details of the implementation of the procedure are illustrated through a case study.","PeriodicalId":407048,"journal":{"name":"2007 European Control Conference (ECC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133511813","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 plans must have a finite descriptive length, and can be expressed by means of words chosen in an alphabet of symbols. In this way, such plans can be sent through a limited capacity channel to a remote system, where they are decoded in suitable control actions. The choice of this symbols is essential to efficiently encode steering plans. To this aim, in this paper, we state the problem of finding symbols maximizing the interval of points reachable by the system along paths with constrained length. We focus on the problem with two symbols, and compare the results with those produced by plans not accounting for the length constraint. Moreover, the behavior of a simple helicopter, steered by both kinds of plans, has been simulated, in order to illustrate the power of the overall control system, and to emphasize the improvements introduced by the new plans.","PeriodicalId":407048,"journal":{"name":"2007 European Control Conference (ECC)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133632420","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}

It is then shown how the parametric matrix can be optimally chosen using a numerical optimization technique so that feedback matrices have minimum norms. Such minimum-norm feedback gains naturally lead to smaller control signals and are useful in reducing noises. The distinguished features of the algorithm making it applicable to even very large practical structures are: (i) the algorithm works directly in quadratic setting without any need to transformation to a standard state-space form, which might require ill-conditioned matrix inversion and destroys the exploitable structural properties, (ii) no model reduction is needed, no matter how large the problem is, (iii) knowledge of only a small amount of eigenvalues and eigenvectors of the associated quadratic eigenvalue problem that can be computed using the state-of-the-art matrix computational techniques, is sufficient for its implementation, and (iv) the algorithm is capable of exploiting the structural properties of the system, such as the sparsity, bandedness, symmetry and positive definiteness, etc., in a computational setting.","PeriodicalId":407048,"journal":{"name":"2007 European Control Conference (ECC)","volume":"218 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133679026","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}
