摘　　要：基于变极点状态反馈控制理论，对电液力伺服系统进行了数控软硬件的工艺设计及其实现。其特点是将最优跟踪的性能泛函与工程中希望的动态品质相结合，并根据实际工况自动改变系统极点，从而较好地解决了稳定性与响应速度的矛盾。在线测试结果表明，该设计使系统带宽提高一倍以上。Based on the theory of variable pole state feedback control,this paper makes the process design and implement of NC software and hardware on electro-hy-draulic force servo system.It features the performance functional of optimal track control corresponding directly to the expected dynamical quality in engineering.And it changes the system pole automatically according to practical situation,to solve the contradiction of the system stability and response time satisfactorily.The results of the experiment on the line showed that this design increased the system bandwidth by twice over and improved the system output waveform remardably.
