摘　　要：为了提高液压控制系统的反应速度和控制精度,克服传统电液伺服系统的动态结构和参数易受干扰等缺点,采用Antiwindup补偿的PID算法,设计基于32位浮点DSP芯片TMS320C6713和双口RAM的CPCI总线的闭环位置数字控制系统.试验表明,该系统硬件可靠性高,柔性好,满足数控液压系统的快速反应和精度要求,大大降低开发、调试和维护成本。In order to improve the response speed and the control accuracy of the hydraulic control system, a closed-loop position digital control system using the antiwindup compensation PID algorithm is designed based on TMS320C6713 and dual-port RAM to overcome the disadvantages of the traditional electro-hydraulic system. The result shows that this system is reliable and flexible to meet the requirements of rapid response and accuracy. The costs of development, debug and maintenance are greatly reduced.
