First, the robot system was converted into an affine nonlinear system through proper torque compensation. Second, the affine nonlinear system was transformed into cascading systems based on differential geometric theory, such that a robust passivity controller was gotten. At last, the robust controller which guarantees that the closed-loop systems were robust, global asymptotic stabilization was attained based on the relationship between the passivity theory and Lyapunov asymptotic stabilization.","PeriodicalId":331407,"journal":{"name":"Fifth World Congress on Intelligent Control and Automation (IEEE Cat.

A new accurate calibration method with multilevel process of camera parameter is presented. Flexibly making use of geometry imaging theory, our algorithm obtain all the parameters through logical organization of solving order, accordingly avoid obtaining possible local optimized problem when solving the non-linear equation. The camera model is aimed at efficient computation of camera extrinsic and intrinsic parameters considering lens distortion, which are solved dividedly. Built on strict geometry constraint, our calibration method gets over the relativity influence of every unknown parameters of traditional calibration way, and makes the error distributed among the constraint relation of parameters, in order to guarantee the accuracy.

The optimization problem is formulated, which belongs to the class of nonlinear combinational optimization, therefore it is difficult for conventional programming methods to find the global optimum. The genetic algorithm is implemented to solve the problem, where possible system parameters are represented as chromosomes on which genetic operators are repeatedly applied to find better solutions. Experiment results demonstrate the genetic algorithm can effectively find out the optimal system parameters to reduce the multi-band jam interference power.","PeriodicalId":331407,"journal":{"name":"Fifth World Congress on Intelligent Control and Automation (IEEE Cat.

This research proposes a novel method for multimodality image fusion based on lifting scheme. In this method, the pixel matrix of input 2-D image are linearized to 1-D pixel sequence by special order on the analysis of lifting wavelet algorithm. Then, the 1-D pixel sequence is decomposed into multi-level subspaces similar to wavelet packet transform. According to the rule of image fusion, coefficients in each wavelet subspace are processed. Lastly, the image is reconstructed with fused coefficients. The whole process of image fusion presents in-place computation and parallel-processing to realize the fast multimodality image fusion. The experiment results demonstrate that the fusion scheme is more effective and suitable to hardware implementation than traditional wavelet-based image fusion.","PeriodicalId":331407,"journal":{"name":"Fifth World Congress on Intelligent Control and Automation (IEEE Cat.

In the GDCS, there are two control targets, one is tracing process output set-point and another is tracing process input set-point. The two control targets can also be divided as the dynamic target and the steady target separately. Because the GDCS is more complex, the traditional control method based on PID algorithm is not applicable any more. To achieve the control targets, a kind of multi-purpose control method is proposed here, which is called the aggregative performance index method. However, based on the aggregative performance index method, a new predictive control strategy with dual optimized horizon is also presented for the GDCS. The simulation results show that the method is powerful and efficient.","PeriodicalId":331407,"journal":{"name":"Fifth World Congress on Intelligent Control and Automation (IEEE Cat.
