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.
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 performance.
