Integrated modular avionics (IMA) is one of the most advanced systems. Its performance greatly impacts on the working condition of aircraft. For enhancing the safety and reliability of aircraft, this paper researches on modeling of IMA degradation. Since the intermittent fault occurs in the degradation of electronic device, it can be considered as one of the characteristics of degradation. The IMA...
In order to solve the multi-robot task allocation problem in logistics warehouse environment, first a robot task allocation model is established in which a corresponding benefit function is established with a consideration of two mainly factors including time window and distance. Then the ant colony algorithm pheromone updating rule is improved combining with working environment and task allocation...
This paper presents a Field-circuit Coupled Time-stepping Finite Element (FE) model of a 1000MW hydro-generator, in which the saturation of iron core, running of rotor, impedance of winding ends, distribution of stator windings and end rings of damper bars are taken into account. The 2-D moving electromagnetic finite element model is coupled with the external circuit elements in this model. Using...
The paper described a structure of three modules diagnosis system for detecting and identifying faults that occur in the sensor and actuator of control systems with input and output signals related to the component itself. The diagnosis algorithm consists of three steps; firstly, generalized morphological filter with multi-structure elements is designed to filter the random noise and impulse noise...
A method of controlling mold temperature control (MTC) solidification process by cooling threshold was presented based on finite element method (FEM) simulation and experiments research. The outcome provides a basis for selecting MTC parameters. The 3D transient heat transfer analysis was done in various conditions which include the cooling threshold of 500, 20, 400, 440, and 300degC respectively...
