摘要
为解决采棉机采棉头液压马达由于负载不断变化引起的转速不稳定和不同步的问题,采用AMESim和MATLAB/Simulink联合仿真的方法,对采棉头液压系统进行了AMESim液压系统建模,在施加不断变化的负载情况下进行PID控制和模糊自整定PID控制仿真。结果表明:施加PID控制要比不施加任何控制的液压马达转速更加稳定,转速更加趋近于设定值;模糊自整定PID和PID控制都可以使液压马达转速趋近于设定值,但模糊自整定PID控制比PID的控制马达同步精度更高。
In order to solve the problem that the speed of the hydraulic motor of cotton picking head is unstable and nonsynchronous due to the constantly changing load,the AMESim hydraulic system of cotton picking head was modeled by using AMESim and MATLAB/Simulink co-simulation,and the PID control and fuzzy self-tuning PID control simulation wer carried out under varying loads.The results show that the speed of the hydraulic motor with PID control is more stable and more close to the set value than that without any control.Both fuzzy self-tuning PID and PID control can make the speed of the hydraulic motor close to the set value,but the synchronization accuracy of the motor controlled by fuzzy self-tuning PID is higher than that by PID control.
