中文摘要：

应用于火炮反后坐装置中的磁流变阻尼器可代替制退机提供后坐阻力。为得到理想的后坐阻力动态特性，要求其阻尼力控制系统响应快速，以实现阻尼力的输出跟踪控制。对所设计长行程磁流变阻尼器进行了冲击试验，测试其输出阻力的动态响应时间。由于试验结果并不理想，因此利用非线性逆系统方法对磁流变阻尼器跟踪控制系统进行了设计校正。最后，对校正后的磁流变阻尼器控制系统及后坐阻力动态特性进行了仿真分析，结果表明，改进设计后的磁流变阻尼器控制系统具有良好的跟踪性能，后坐阻力动态特性令人满意。

英文摘要：

The application of magneto-rheological dampers for controlling recoil dynamics was investigated. To provide the optimal damping force, fast response time of MR damper was required so that good damping force tracking can be obtained. Impact tests were done to evaluate the response time of the special designed long stroke MR damper, corresponding to the step signal of the operating current. As the test results were unsatisfied, modified tracking control system of MR dampers was designed using methods of nonlinear inverse system. The recoil dynamics with the modified control system of the MR damper was analyzed by numerical simulations. The results indicate that the modified control system of MR dampers has a good tracking ability, and the recoil dynamics are satisfied.
