中文摘要：
针对电动汽车电驱动系统的非线性特点，采用端口受控Hamilton系统理论与无源性控制原理研究了计及铁损的电动汽车用感应电机系统的建模和控制问题．首先，选取系统的总能量作为Hamilton函数，推导出考虑铁损的感应电机端口受控Hamilton模型，然后利用系统的互联和阻尼配置以及能量成形对闭环电动汽车电驱动系统进行无源控制，并分析了闭环系统的稳定性．由于闭环系统的Hamilton函数可作为Lyapunov存储函数，从而使控制器设计和稳定性分析更容易，控制器更加简单和易于实现．仿真结果验证了新控制策略的有效和快速性．
英文摘要：
In view of the nonlinear characteristics of the electric vehicle drive system, we apply the port-controlled Hamilton system theory and the passivity-based control theory to investigate the modeling and control of induction motor with iron losses in electric vehicles. The total energy of the system is considered the Hamilton function, based on which the port-controlled Hamilton dissipative model of the induction motor with iron losses is derived in a synchronously rotating frame; and then, the passive controller of the closed-loop electric vehicle drive system is designed by using the method of interconnection and damping assignment. The stability of the closed-loop system is analyzed as well. Because the Hamilton function of the closed-loop system is used as the Lyapunov storage function in the global stability analysis of the system, both the design and implementation of the controller becomes simpler and easier. The simulation validates the efficacy of the proposed control scheme.
