| 摘 要： | 为精确控制轮毂电机驱动电动汽车各轮毂电机的扭矩，获得更好的车辆动力学控制性能，利用Matlab／Simulink对再分配伪逆算法（Redistributed Pseudo—Inverse algorithm，RPI）、层叠广义逆法（Cascading Generalized Inverse algorithm，CGI）和加权最小二乘法（Weighted Least-Squares algorithm，WLS）进行数值仿真，对这3种算法从计算速度、迭代次数和计算精度等方面进行对比分析与评价，结果表明WLS综合性能最优．

| Abstract: | To control the torque of all in-wheel motors for in-wheel motor drive electric vehicle accurately,and to achieve the better control performance of automotive dynamics,numerical simulation are performed on Redistributed Pseudo-Inverse algorithm(RPI),Cascading Generalized Inverse algorithm(CGI) and Weighted Least-Squares algorithm(WLS),and the calculation speed,iteration times and calculation accuracy of the three algorithms are compared and evaluated. The result shows that WLS has the best comprehensive perf... |
