基于遗传PID的动静液复合转向优化控制研究
Research on GA-PID based hydrodynamic and hydrostatic steering system optimization
摘要
Abstract
As the tracked vehicles often run in harsh environment, a certain type of tracked vehicles with hydrodynamic and hydrostatic steering mechanism often have a big pressure fluctuation in the hydrostatic system in the steering process and the steering properties are seriously affected. In order to smooth match the hydrodynamic and hydrostatic steering mechanism, we implemented the electro-hydraulic proportional valves instead of the oil-filling valves that equipped in the real vehicle and modeled the steering system in the Matlab/Simulink platform in this paper. A PID controller that optimized by the Generic Algorithm (GA) can control the oil flowing into the hydraulic equipped according to the fluctuation of pressure was designed. The simulation results showed that the optimized system inhibited the pressure fluctuation well, with a rapid dynamic response and good steering performance.关键词
