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。

Abstract: 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, determined 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 regenerative 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 simulation models of regenerative braking SMC strategy were established in the Matlab/Advisor. The simulation results 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.
