摘　　要：构建了液压缸装配专用设备电液伺服系统的数学模型,提出基于CMAC与PID复合控制算法的控制策略,克服传统PID控制存在的参数很难自整定、系统超调量过大、动态响应速度过慢等问题。仿真分析表明,采用CMAC与PID复合控制算法具有很好的控制效果,可以提高系统的动态特性,减小系统的超调量,增强系统的稳定性。In this essay, a mathematic model is established for an electro-hydraulic servo system for special-purpose hydraulic cylinder assembly equipment, and a control strategy is put forward that is based on a CMAC/PID composite con- trol algorithm, which helps solve issues associated with conventional PID control, like too much difficulty in making param- eters make self-adjustments, excessive overshoot for the system, too slow a dynamic response speed, etc. It is indicated in simulation analysis that use of the CMAC/PID composite control algorithm can generate an excellent control effect, improve the system＇s dynamic characteristics, reduce the system＇s overshoot, and enhance its stability.
