In this paper, we present a method for physics-based dynamic deformation simulation of 3D object. In interactive virtual deformation simulation, there are many common linear and non-linear elasticity models for various deformable situations. We discuss constitutive models of common materials and analyze their differences. On account of their homogeneous and isotropic material properties, these models...
In order to solve the problem that the fault characteristics of hydraulic pump have ambiguity and signal-to-noise of inspected signals is low, a new method based on characteristics of the energy spectrum of vibration signals combing rough set (RS) and principal component analysis (PCA) algorithm is proposed in this paper. This algorithm processes noise abatement for collected vibration signals by...
In this paper, we study the cooperative control of linear, discrete-time multi-agent systems with fixed information structure and without communication delays. Based on the bilinear matrix inequality (BMI), the sufficient condition is obtained for the stabilization of multi-agent systems composed of N agents. Then, the design problems of cooperative controllers are converted into the optimization...
Usually the theoretical approach to obtain the strain modal are based on the traditional parameter identification methods; however, due to Complexity and low-precision of the traditional identification methods, it is obviously not practical for the large tower structure; based on the own characteristics of tower structures and combined with the modal analysis theory, feasibility of the strain modal...
A flux linkage estimation method for induction motor based on extended Kalman filter theory (EKF) is presented in this paper. In order to improve the accuracy of filtering, genetic algorithm (GA) is introduced to optimize the noise matrix, and also filtering parameters in EKF. Simulation results show that the flux observer with optimized filtering parameter has better estimation accuracy and dynamic...
In this paper, the real maximal robust stability radii are investigated for uncertain continuous-time symmetric commutable singular (SCS) systems described by dynamic equation. First, one structured uncertainty is defined; then we provide an explicit expression for the real maximal robust radii. Based on it, the problem is transformed into a special rank reduction problem that is the rank of the perturbed...
