High-altitude calibration of CA6DL2-35E3R common rail diesel engine was finished on engine high altitude simulating environment test bed. The interactions between injection parameters and its impact on engine high altitude performance were studied. Results show that the fuel delivery per cycle per cylinder increases with the adwance of injection timing and the increase of common rail pressure at the...
The gyro drift error of cruise missile is the main factor that affects the navigation accuracy. In the non-stop flight segment of cruise missile, the gyro drift error can cause the deviation in the horizontal and vertical direction through affecting the acceleration. Neural networks have a strong self-learning nature, adaptive capacity and non-linear properties. In the paper, we constructed mathematic...
In this paper, a robust neural network-based on line learning and artificial immune algorithm is proposed for a boiler combustion optimization system. This method involves a model modification and parameter optimization to the normal use of boiler combustion optimization system neural network. Neural network consists of working sets and standby sets of implicit strata real-time adjusted set number...
Based on the study of traditional Simple adaptive control (SAC), the dissertation combines SAC with intelligence control algorithms, and proposes a new Intelligent SAC. The basic algorithm of SAC is improved, and cerebellar model articulation controller algorithm of neural network is combined with the SAC algorithm, the SAC controller adopts the control algorithm of adaptive method, but the construction...
Modulation recognition of communication signal is to confirm the modulation style of communication signal in the condition with much noise. Wavelet transformation has a good localization characteristic in time-frequency domain, while the neural network has characteristics of self-studying, self-adaptation, and high stabilization and can improve the autoimmunization and intelligence of recognition...
High resolution earth observation requires high precision attitude control of satellites, because the chatter of satellites can decay the resolution of the earth observation. Magnetically suspended flywheels (MSFW) with the advantages of no contact, no frication, high precision and long life, are the ideal actuators of high precision attitude control of satellites. But there still are several disturbing...
How to control the mechanical properties of materials is difficult in actual production. In this paper, neural network (NN) and principal component analysis (PCA) have been adopted to simulate and control mechanical properties of CA6NM (called ZG06Cr13Ni4Mo corresponds to Chinese steel code). An optimized NN has been built to analyze and design a kind of material according to its components. This...
