数字式液压伺服系统控制器设计

摘要

In the analysis of the hydraulic control object based on engineering practice , aiming at the disadvantage of the original analog controller, a digital hydraulic servo controller based on DSP + FPGA platforms was designed, by using the classical PID control algorithm to control position of hydraulic motors. The simulation results show that digital hydraulic servo control system has good speediness, stable control and high precision.%在分析液压控制对象的基础上,针对原模拟控制器的不足,根据工程实际,设计一种基于DSP+FPGA平台的数字式液压伺服控制系统,采用经典的PID控制算法控制液压马达位置.仿真结果表明:该数字式液压伺服控制系统快速性好,稳态控制精度高.
