中文摘要：

为了提高混合动力汽车制动能量回收率，提出一种基于设定曲线的串联式混合动力汽车电机的滑模控制策略。首先，确定一条电机的高效运行曲线，建立永磁同步电机发电过程的数学模型。然后，在再生制动控制系统中设置一个固定边界层滑模控制器，对永磁同步电机发电转矩进行控制，使电机工作点处于高效运行曲线附近。最后，在Matlab／Advisor中搭建再生制动滑模控制仿真模型。仿真结果表明，与未采用电机效率优化的比例分配控制策略相比，本文设计的滑模控制（Sliding Mode Control，SMC）策略有效地提高电机制动过程中的能量回收率。

英文摘要：

In order to improve braking energy recovery rate of series hybrid electrical vehicle （SHEV）, a sliding mode control （SMC） strategy for the motor of SHEV was proposed based on the set curve. First, de- termined the efficiency curve of motor, and built a mathematical model of generation process of permanent magnet synchronous motor. Then, a sliding mode controller with fixed boundary layer was configured in re- generative braking control system for controlling generating torque of permanent magnet synchronous motor, which made the motor operating point located near the efficient operation of the curve. Finally, the simula- tion models of regenerative braking SMC strategy were established in the Matlab/Advisor. The simulation re- suits show that the designed SMC strategy can improve the energy recovery rater effectively during braking, compared with the proration strategies with non-optimal generator control.
