摘　　要：由于铁钻工的液压比例系统参数变化程度较大且有负载干扰,性能要求无法通过一般控制方法得到全部满足。PID控制方法算法简单、鲁棒性高、可靠性好。设计PID控制器,使PID参数自适应变化,省去繁琐的参数调试过程。利用Fluid SIM进行仿真,分析电液比例系统在PID控制下的控制效果,发现系统的非线性和负载干扰等影响均能被PID控制器较好地克服,使系统的稳定性和动态性能得到提高。Because the hydraulic proportional system parameters of iron roughneck vary greatly and have load disturbance, the performance requirements cannot be fully met by the general control method. PID control algorithm is simple, robust and reliable. The PID controller is designed so that the PID parameters can be changed adaptively, and the tedious parameter debugging process is avoided. By using FluidSIM, analyzes lhe eontrol efteet of electro-hydraulic proportional system under PID control. It is found that the influence of nonlinear and load disturbance of the system can be well overcame by PID controller, and the stability and dynamic performance of the system can he improved.
