摘　　要：针对液压无级转速系统建立了动态特性数学模型,仿真结果表明采用稳定边界PID控制算法和双闭环反馈控制的转速控制系统具有稳定性好、响应迅速、抗负载扰动能力强的特点,为液压无级转速控制系统的设计、校正提供了依据。For hydraulic stepless speed control system, a mathematical model of double closed loop speed control system is built up. The resuit of simulation indicates that, when adopted PID control algorithm and double closed loop feedback, the dynamic response, stability, error and robustness of the speed control system are satisfying. So this paper provides the theoretical basis for emulation and calculation of speed control system.
