摘　　要：由于压铸机液压控制系统惯性大,采用常规方法设计的伺服系统转速环容易转速超调导致压力过冲,针对此问题,提出一种应用于压铸机液压伺服系统的抗饱和转速环设计方法。对采用i_(d)=0矢量控制方法的永磁同步电动机伺服系统进行了转速环设计,包括转速环的结构设计和参数整定方法。结合实际应用案例,进行了仿真分析和实验验证。仿真分析表明抗饱和算法能有效抑制转速超调;实验结果表明,压铸机液压系统压力过冲小,证明所提转速环设计方法有效。Due to big inertia of casting machine hydraulic system,there is speed overshot in servo system speed loop designed by traditional method,so as to cause pressure overshoot.Aiming at the problem,a design method of anti-windup speed loop is presented,which is applicable to molding machine servo system.Speed loop of servo system for permanent magnet synchronous motor controlled by i_(d)=0 vector technology is designed,speed loop structure design and parameters setting method are introduced in detail.Application case is analyzed and experimented.Simulation results show that speed overshoot is suppressed,experiment results show that there is small overshoot in casting machine system,then the validity of design method is proved.
