This article discussed the compensation characteristic of multi-way valve outlet pressure compensation in crane hydraulic system. The author using the simulation software AMEsim to two working loop to build a simulation model, with a certain type multi-way valve determine parameters, draw a series of simulation results. This article aims at explaining the characteristic and principle of the outlet...
This paper based on the control system with integral element, establishes the fuzzy control system and designs the fuzzy controller. Though reasonable design the parameters in the fuzzy controller, studies on the control performance for the control system. After changing the shape of the membership function, the quantization factor, the control rules and the number of fuzzy linguistic variable, will...
An image fusion algorithm based on Self-Generating Neural Networks??SGNN?? is presented in this paper. Three features are defined and proved to indicate the clarity of an image block. These features are extracted and fed into the neural networks, which learn to produce a Self-Generating Neural Tree (SGNT) to determine the clustering result. registered source images will create SGNTs. As for one of...
The paper introduces the control method of the fuzzy sliding-mode control (FSMC) for electro-pneumatic proportional position system, designs the discrete FSMC system and its controller. The sliding surface and its switch function are designed by using the pole assignment method. The control law of the sliding mode is based on the exponential trending law. The switch function s(k) and its error ds(k)...
