摘　　要：根据污土铣刨收集机械中螺旋滚筒液压悬挂系统具有非线性、时变性和外负载干扰的特点,提出污土铣刨收集机械螺旋滚筒悬挂系统模糊PID控制的设计方法,建立模糊推理系统,并利用Matlab/Simulink软件对悬挂系统切深进行模糊PID复合控制和PID控制仿真,研究结果表明,采用模糊PID复合控制策略比PID控制更能适用于螺旋滚筒悬挂系统。According to non-linearity, time-variable and external interference of soil pollution spiral milling machines to collect hydraulic cylinder suspension system, design method based on fuzzy PID control has been proposed to simulate the model of cutdepth control system based on Matlab/Simulink ; and fuzzy inference system has also been established. It is shown that fuzzy-PID control method has advantages of sensitive response, good time-variable and little overshooting and is an effectively controlling strategy.
