摘　　要：利用自动控制理论,对多关节凿岩台车的不对称油缸电液伺服系统进行了分析。通过计算油缸的液压弹簧,推导出不对称液压油缸的固有频率。同时给出了电液伺服系统的传递函数、控制数学模型的简化计算方法以及该系统的稳定性判据。对系统控制精度进行了必要的讨论,提出了提高不对称油缸电液伺服系统性能的方法和途径。By using automatic control theory, analyze the asymmetric cylinder electro- hydraulic servo system of multi - joint rock - drilling jambo. The inherent frequency of the asymmetric hydraulic cylinder is derived by calculating the hydraulic springs. At the same time, the transfer function of the electro - hydraulic servo system, a simplified method of the mathematical control model and the system stability criterion are given. Based on the necessary discussion of systemic control accuracy, derive ways and means to improve the performance of the asymmetric cylinder electro - hydraulic servo system.
