摘　　要：针对一个具有高速、控制精度要求高的大惯性电液位置伺服系统,通过理论分析和实验测试,确定了系统的主要特征参数,并建立了与实际系统相吻合的数学模型。根据系统自身的特性和控制指标的要求,采用了基于指数趋近律的滑模控制策略。在仿真实验验证控制方法有效性的基础上,将其应用到了实际系统。系统的测试结果表明,被控对象具有平稳的动态过程和理想的位置控制精度,性能达到了使用要求。For a large inertia electro - hydraulic position servo control system with high speed and highaccuracy requirements, main parameters are determined by combining theoretical analysis with experiments ;subsequently the mathematical model suitable for the actual system is established. After analyzingthe characteristics of the whole system and the requirements for control performance, the sliding - mode controller based on exponential approach law is designed. At last,the effectiveness of the control method is verified by simulation results,and this method is tested in the actual system. The illustrate that the system has the stable dynamic process and satisfactory position trackrequirement of engineer application.
