The hybrid control consists of the parallel construction of the two-cell immune control and conventional PD feedback control. The immune controller has strong robustness and adaptability, and one-order integral characteristics. Therefore, the immune controller can realize the adaptive and constant control of the system with no error, and the PD controller can realize stability and rapidity. Simulation for the temperature control of electric heating dryer was carried out under such a control that has parameter uncertainty. The results verify that this hybrid control is better rapidity, smaller overshoot, and better robustness than a proportional-integral-derivative (PID) control. The temperature control obtains satisfactory control effectiveness","PeriodicalId":375135,"journal":{"name":"2006 6th World Congress on Intelligent Control and Automation","volume":"199 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121071661","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}

Therefore, in this paper a new mixed filter algorithm is proposed for filtering the image corrupted by difference noises. Firstly, we construct adaptive structure using neighborhood contrast measure; secondly, divide the image into smoothness, edge and unconfirmed regions based on the adaptive structure; then, adopt corresponding filter for different regions. The algorithm does not need a priori knowledge of images and noises. We perform experiments on the image corrupted by Gaussian and impulse noises, by using average filter with maximization and minimization for the smoothness region, unidirectional median filter for the edge region and median filter for the indefinite region. The experiments show that the proposed algorithm is feasible and efficient","PeriodicalId":375135,"journal":{"name":"2006 6th World Congress on Intelligent Control and Automation","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121213954","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}

Fourier series expression of phase self-inductance under the assumption of negligible mutual effect and various losses is introduced to describe the nonlinear dynamic model of SRM. By virtue of Matlab/Simulink, the models of various subsystems are achieved and the modeling procedure is described in detail. By the organic combination of subsystems, the whole simulation model of SRM drives is established. In addition, to improve the adjustable speed performance of SRM drives, the double closed loop control strategy based on a chopping controller in the current loop and a fuzzy+PI controller in the speed loop is proposed. Simulation results have shown the rationality of model and validity of control strategy. The model developed here can be widely used and is easy to modify, which offers a good platform for choosing the best control strategy","PeriodicalId":375135,"journal":{"name":"2006 6th World Congress on Intelligent Control and Automation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127168185","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}

For improving estimate precision, the industry model was corrected on-line by the error between analyzed value and estimated value and was updated automatically by the dynamic modeling database.

An image decomposition method called empirical mode decomposition (EMD) is first addressed in this paper, and then the problems such as searching local extrema points and boundary extension are discussed in detail. On this basis, a new image zooming method using 2 dimensional (2D) EMD technique is proposed. The main procedures are designed as the following: first, by 2D EMD method, an image is decomposed into several layers, where each of them contains different details or possesses different roughness; second, each layer is zoomed using a combination method with different parameters that are proportional to roughness of that layer, at last, the final zooming result is reconstructed from the combined interpolated layers.
