A reasonable mathematical model of semi-active suspension is established based on a quarter vehicle. A fuzzy controller is proposed and its fuzzy rules are deduced using Matlab Fuzzy logic control toolbox. Simulation model for the whole system is completed by means of Matlab/Simulink. The response curves under random road profile excitations of semi-active suspension are given, which are compared...
Considering the unsteadiness and unpredictability of a practical task running environment due to the unsteadiness of network communication and the estimation deviation, it is necessary to introduce fuzzy concept and theory to the scheduling and performance control of the soft real-time application systems oriented communication and network fields. In this paper, a new adaptive soft real-time task...
A two-dimensional ultra-precision positioning system with high-speed and large-range which can be used in a micro-nanometer machining has been studied in this paper. The macro-micro dual-drive system is used to satisfy these positioning requirements. Because of the strong nonlinearity of the piezoelectric devices, such as the hysteresis and the creep, and the influence of the highly accelerated run...
According to the positioning accuracy requirements of the two-dimensional precision positioning system with high speed, wide platform, large range and linear motor driving, an intelligent positioning control system based on the linear motor is studied in this paper. The precision positioning experiment is also conducted. The experimental result shows that the positioning accuracy and the dynamic performance...
According to the positioning accuracy requirements of the two-dimensional precision positioning system, a two dimensional intelligent positioning control system is used in our study.
