摘　　要：推导出非对称阀控非对称液压缸系统的基本动态方程,并建立了该系统的非线性数学模型和线性化数学模型。利用MATLAB/SIMULINK对两模型进行动态仿真,研究了系统在不同输入信号和参数变化下的动态特性。对比分析仿真结果可知,两模型吻合很好,证明所建立的数学模型的正确性。The basic dynamic equations of asymmetrical valve controlling asymmetrical hydraulic cylinder system were educed. Its nonlinear model and linearizing model were established. The dynamic characteristics of the two models under different input signals and parameters were simulated by the use of SIMULINK Toolbox of MATLAB. By comparing and analyzing the simulating results, the two models match well, which proves the correctness of the two models.
