摘要
首先,在速度分区控制的基础上,提出了分区电流分配方法,根据电动汽车系统低速大转矩、宽调速范围的需求,实现电流最优化,提高电机利用率;其次,将各电流与给定转矩线性化拟合为低阶多项式,提高工程应用性;最后利用状态反馈线性化实现全局范围电流环解耦控制。仿真结果表明,所提出的控制方法可达到预期效果,提高电机效率,最高转速提升到额定转速的3倍,电机动、静态性能提升,对HESM的电动汽车系统综合性能得到了最优化控制。
Firstly,a partition current distribution method was proposed which was based on the speed zone control. Aiming at the requirements of the low speed and wide speed range of electric vehicle system,the current utilization was optimized and motor utilization was improved. Secondly,the low-order polynomial was fitted with the given torque respectively to improve the engineering application. Finally,the global range current loop decoupling control was realized by state feedback linearization. The simulation results show that the proposed control method can achieve the expected effect,the motor efficiency is improved,the maximum speed is raised to three times as the rated speed,the motor dynamic and static performance are improved,and the overall performance of the electric vehicle of HESM is optimized.
