Abstract:New stability conditions for complex switched systems are presented. We propose the concepts of attractive region and semi-attractive region, and to be a tool for analyzing the stability of switched systems with unstable subsystems. Based on attractive region the sufficient conditions with less conservative for stability of switched systems have been established, there is no limitation for all members of the system set to be stable. Since our results have considered and utilized the decreasing span of oscillating solutions of the switched systems, they are more practical than the other presented ones of stability of switched systems, and need not resort to multiple Lyapunov functions. | |||

Abstract: We develop two-dimensional (2-D) face test to determine the stability of a nominally stable linear state-space model being subjected to real structured perturbations. The system matrices are assumed to depend linearly on set of interval parameters. Since the system matrix family of the uncertain systems belongs to a kind of polytopes of matrices, we can apply a 2-D face test, which is necessary and sufficient condition for the robust Hurwitz or Schur stability for the uncertain matrices. Examples are given to verify the 2-D robust stability test to be correct. | |||

Abstract:The characteristic polynomials of polytopes of recursive 2-D continuous-discrete systems are polytopes of bivariate (2-D) polynomials. Since the root domain of bivariate polynomials is in 2-D complex space, to be different from that of 1-D polynomials, the analysis for robust stability of polytopes of 2-D polynomials is much more complicated than 1-D case. To solve the problem of stability test of polytopes of recursive continuous-discrete systems, we establish necessary and sufficient conditions of robust Hurwitz-Schur stability of polytopes of bivariate polynomials. We show that the robust Hurwitz-Schur stability of a polytope of 2-D polynomials can be determined by testing the stability of the edges of the polytope. An example has been given to demonstrate the applicability of our new approach. | |||

Abstract:A spiking-neuron based cognitive model with classical conditioning behaviors is proposed. With a reflex arc structure and a reinforcement learning method based on the Hebb rule, the cognitive model possesses the property of ‘stimulate-response- reinforcement’ and can simulate the learning process of classical conditioning. An experiment on the inverted pendulum validated that this model can learn the balance control strategy by classical conditioning. | |||

Abstract:A growing cognitive model of motor balance skill, which simulates the manners of human beings and animals in motor balance skill learning, is constructed. A neuro-controller based on the model is proposed to balance an inverted pendulum. The cognitive model, whose architecture is similar to the reflex arc of the biologic nerve, adopts a growing algorithm from reference to Growing Cell Structures in order to perform the pattern classification in the nerve center. This growing mechanism is able to be evolved through the con-tinuous growing of the new nerve cell. And reinforcement Hebbian Synaptic Modification is used as the self-learning method in the cognitive model to make the neurons in difference fields to respond to the different stimulus in the best way. The experimental results are shown that the growing cognitive model can interact autonomously with the environment and develop the motor balance skill by the growing manners of neural system itself. | |||

Abstract: A constructive theorem of generalized synchronization (GS) for unidirectionally coupled array differential equations (ADE) is presented. Based on the theorem, one can design a GS driven ADE via a driving chaotic ADE and a C^1 diffeomorphism. As an application, a smoothed Chua | |||
