Time scheduling using agent technology

This paper is a study on agent technology, and discusses the feasibility of achieving time scheduling using agent technology. An agent construction tool - JACK is introduced. As an experiment, the paper describes a specific implementation process for a tutorial scheduling system in a university environment. The research demonstrates that agent technology has potential in the same area of ambiguous decision-making

Domain of attraction of hysteresis-series based chaotic attractors

This paper discusses the domain of attraction and its sensitivity for a class of chaotic attractors generated by using second-order linear systems with hysteresis-series. It is found that the domain of attraction of the chaotic attractors is determined by an unstable limit cycle. The chaotic dynamical behaviors are demonstrated by using the Poincaré map. The sensitivity of the domain of attraction with respect to the system parameters is studied and some simulation results are presented

Complex dynamic behaviour in a linear third-order continuous system with hysteresis series

This paper studies dynamic behaviour in a linear third-order continuous system with hysteresis series. The l-dimension (l-D) n-scroll chaos and l-D abnormal chaos can be obtained with one state variable is input to hysteresis series. Complicated limit-circle and 2-D multi-scroll chaos can be obtained when two state variables are input to hysteresis series

Fault location in power distribution networks using sinusoidal steady state analysis

This paper proposes a fault location method based on sinusoidal steady state analysis which can locate the single phase-to-ground short-circuit fault with single-ended measurement in an overhead three-phase electric power distribution lines. By measuring and calculating certain fundamental parameters of the system as well as the voltages and currents at the sending-end, which contain corresponding fault information, the location and resistance of fault candidates can be determined by solving nonlinear distributed-parameter equations. Physical model experiments show that this method performs well

Generation of multi-scroll chaos using second-order linear systems with hysterresis

This paper proposes a method of generating multi-scroll chaos using second-order linear systems with a hysteresis series. It shows that multi-scroll chaos can be produced in any direction in the phase plane. Furthermore, two-dimensional multi-scroll chaos can be generated as well. Both computer simulations and circuitry implementation have verified the multi-scroll chaos generation scheme

Synchronization of the duffing oscillator by using terminal sliding mode control

This paper presents a terminal sliding mode controller used for the chaos synchronization of the Duffing oscillator. The error dynamical equation between the master subsystem and the slave subsystem is established firstly. Then the controller drives the error variables of the error dynamics to zero. The time taken to reach the equilibrium point from any initial states is guaranteed to be in finite time and the chaos synchronization is realized by using the controller. Simulation results are presented to validate the analysis

n-scroll chaotic oscillators by second-order systems and double-hysteresis blocks

A new circuit design for generating n-scroll chaotic oscillators using a linear second-order unstable system with double-hysteresis series is proposed. The hysteresis series is realised by building blocks. With this proposed scheme, the n-scroll chaotic attractors can be easily generated along the directions of the system state variables
