中文摘要：
势能回收可有效降低动臂频繁上下往复作业过程的能耗。其中，永磁发电机是实现回收功能的关键部分，其性能对能量转换和运动控制具有重要影响。因此结合应用工况的特点，对势能回收用永磁发电机控制系统进行研究和设计。针对系统输入输出参数存在较大波动，提出分别在电流控制环引入增益自适应、在转速控制环引入负载估计及补偿的控制方法。基于液压加载的永磁发电机控制系统台架进行了试验研究。结果表明，系统具有良好的电流和速度控制性能，且抗干扰能力得到显著改善。
英文摘要：
Potential energy recovery can significantly reduce the boom energy consumption produced by frequent rising and lowering operations. As a critical component, the performance of the permanent magnet generator applied in energy recovery has a strong influence on energy conversion and motion control. Therefore, it is necessary to research and design the control system of the generator. Since there exist input and output parametric fluctuations, adaptive control and disturbance compensation were proposed in the current loop and the speed loop, respectively. Experiments were implemented on a test bench which is loaded with hydraulic approach. The results show that the good current and speed control performances were realized, and anti-disturb capability was also improved.
