【摘要】 建立了高地隙四轮驱动喷雾机底盘工作过程中的运动模型,以相对滑转率为控制目标,提出了一种基于模糊控制的防滑控制系统。设计了防滑控制器,在Matlab/Simulink环境下进行了仿真,构建了防滑电液系统试验装置,进行了模拟试验,结果表明高地隙四轮驱动喷雾机的电液防滑控制系统效果良好,控制响应时间1.85 s,精度达到97.3%。更多还原

【Abstract】 A motion model of a high clearance four-wheel drive spray machine chassis of the work process was established and a slip control based on fuzzy control system was realized through the relative slip rate as control objectives.Anti-skid controller was designed,simulation had been carried out by Matlab/Simulink and the anti-skid electro-hydraulic system test device was constructed.The simulated test results showed that the four wheel drive high clearance spraying electro-hydraulic anti-skid control system worked well,the control response time was 1.85s,and the control precision reached to as accurate as 97.3%.更多还原
