摘　　要：动态响应速度是先进汽车动态测试中的关键,在研究直接转矩控制的基础上,提出用其设计的测试系统方案,并建立了仿真实验模型。在设计中,采用电惯量替代传统的机械惯量模拟汽车运动惯量。由于直接转矩控制能快速响应转矩指令,使得研究的电惯量模型能精确的控制汽车加速度,突破了单纯速度跟踪的限制。仿真结果也表明性能优越。Response speed is the key to advanced vehicle dynamic testing. A new kind of testing system was put forward based on direct torque control which takes response speed into full consideration. Then a simulation model was established according to it. In the design, vehicle motion inertia is simulated by the way of electrical inertia instead of mechanical inertia. Because direct torque control has quick response to torque command, the acceleration of vehicle is kept in accurate control using electrical inertia. The simulation results show that the performance is ideal.
