摘要/Abstract

摘要： 为提高履带车辆发动机转速的抗负荷扰动性，并改善整车行驶过程的转速控制效果，在基于转矩控制架构下设计了前馈-反馈全程调速控制算法。该算法基于平均值模型和曲轴动力学模型设计发动机负荷估计算法，利用某6缸直列泵柴油机进行台架试验研究其在稳态动态工况的估计精度。进行了动力传动系统仿真研究，研究结果表明：该算法能够显著提高转速控制的抗负荷扰动能力；在整车加速过程中保持了较快的转速调节时间，避免了控制参数的重复标定；踏板-转速跟随特性的提高能够减少履带车辆意外换挡的出现。

Abstract: In order to improve the load disturbance rejection and rotating speed control effect for the tracked vehicle engine, a feedforward-feedback speed control algorithm is proposed according to the torque-based architecture. A load estimation algorithm is designed based on mean value model and crankshaft dynamic model. The estimation accuracy of the proposed load estimation algorithm is validated under steady and transient conditions. The feedforward-feedback speed control algorithm can significantly improve the capability of load disturbance rejection in the simulation of powertrain. The reseach results show that a rapid speed control effect can be achieved and repetitive calibration of speed control parameters can be avoided during acceleration process of tracked vehicle. The improvement in pedal-rotating speed following characteristics leads to the reduction in unexpected gear shifting of tracked vehicle in a driving cycle.
