摘要

To meet the requirements of aircraft tractor,the main parameters of power system were optimized and the optimized results were analyzed by a mathematical model.The braking control system structure and the working policy were designed according to the requirements of regenerated hydraulic braking system.The dual hydraulic braking style was analyzed with consideration of braking conditions greatly influenced by parameter perturbation,so that the optimal working mode was obtained.The control algorithm was proved to be efficient based on the design of ANN fuzzy PID controller and the performance test on the test-bed simulated the hydraulic hybrid tractor.%为了将液压混合动力技术应用于飞机牵引车,按照飞机牵引车的性能要求,对动力系统的主要参数进行了优化匹配,用数学建模方法对优化结果进行仿真分析;根据再生储能制动需求,设计制动控制系统结构和工作策略;针对受参数摄动影响显著的制动工况,进行双液压蓄能器储能制动配置方式的对比分析,得出最佳工作模式;设计神经网络模糊PID控制器,并在液压混合动力车辆模拟试验台进行性能测试,验证了控制算法的有效性.
