| 摘 要： | 针对高精度电动燃油调速系统在负载突变工作时燃油增压与燃油流量调节的稳定性问题，研究了前馈补偿控制策略，提出了一种基于降维负载转矩观测器的抗负载扰动控制方法。该方法实时对电动调速系统的同步电机输出转速与负载转矩进行观测，并将观测到的负载转矩补偿到同步电机交轴电流，实现闭环调速控制，从而避免了负载扰动影响系统输出转速，减小电动燃油泵对燃油的压力与流量的影响。仿真和试验结果表明，在快速加载与卸载实验条件下所提出的方法的正确性与可行性。

| Abstract: | To solve the stability problem of the high-precision electric fuel pump speed control system during fuel load regulation and fuel flow regulation under abrupt load variantion, the feedforward compensation control strategy is studied and a control method against load disturbance based on the reduced-dimensional load torque observer is proposed. By this method the synchronous motor output speed and the load torque of the electric fuel pump speed control system can be observed in real time. The observed load torque is used for the compensation of the synchronous motor cross-axis current to realize closed-loop speed control, thereby avoiding the effect brought by the load disturbance on the system output speed and reducing the influence of the electric fuel pump on the fuel pressure and flow. The simulation and experimental results show the correctness and feasibility of the proposed method under the conditions of fast loading and unloading experiments. |
