摘要
为满足液态浸渗挤压复合材料工艺自动控制的要求,利用电液比例控制技术和计算机技术设计出了液态浸渗挤压复合材料过程的速度控制系统。在理论分析的基础上制定了PID反馈控制和数字补偿相结合的控制策略,并对该控制系统的动、稳态特性进行了仿真分析。结果表明:该速度控制系统具有高灵敏度、高精度,且有很强的抗负载干扰能力。
A design of speed control system was given to control the liquid-infiltration-extrusion-MMCs process automatically,in which electro-hydraulic proportional control technology and computer technology were used.According to theoretical analysis,a control strategy combining PID-feedback control with digital-compensation was proposed and its performance was analyzed through simulation.The speed control system has high sensibility and precision,and has strong anti-interference of load.
