摘　　要：为解决直驱式容积控制系统存在的电机时滞性、系统死区非线性、系统超调以及差动缸转换过程压力波动等问题,搭建了基于AMESim和Simulink联合仿真的直驱式容积控制压力模型。设计了模糊PID控制器,与传统PID控制进行对比,通过仿真研究,验证了模糊PID控制器在解决电机时滞、系统死区影响、系统超调以及压力波动等问题中具有良好的效果。A direct drive volume control pressure model based on AMESim and Simulink co-simulation was established to solve the problems of motor delay,system dead zone nonlinearity,system overshoot and pressure fluctuation in differential cylinder conversion.The fuzzy PID controller was designed and compared with the traditional PID controller.Through simulation,it is verified that the fuzzy PID controller has good effect in solving problems such as motor delay,system dead zone,system overshooting and pressure fluctuation.
