为了有效地驱动现有的感应电机，必须将其运行过程中的能量损失降到最低。有报道称，在给定的驱动条件下，解析设计的最优转矩和转速轨迹使感应电机(IM)驱动系统的能量损失最小。然而，在已有的分析方法中，铁耗和其他未建模的损耗被忽略了。利用线性矩阵不等式(LMI)方法，提出了一种以能量损失最小为目标的电机扭矩和转速最优轨迹的数值设计方法。从电机的电气输入和机械输出功率两个方面对电机损耗进行了实验测量，并用损耗图表示了测量的损耗数据。损失图由转速ω和电机转矩T组成，评价函数由驱动条件和损失图给出，然后通过求解LMI优化问题得到最优轨迹，使评价函数最小化。通过实验验证了该方法的有效性。
In order to drive the existing induction motors efficiently, the energy loss should be minimized during its operation. It has been reported that the analytically designed optimal torque and the rotating speed trajectories minimize the energy loss of the induction motor (IM) drive system under given drive conditions. In the reported analytical methods, however, the iron loss and other un-modeled loss are neglected. This paper proposes a numerical design methodology of the optimal trajectories of the motor torque and the rotating speed minimizing the energy loss by means of Linear Matrix Inequality (LMI). The motor loss is experimentally measured from the electrical input and the mechanical output power of IM, and the measured loss data are represented by a loss map. The loss map is composed by the rotating speed ω and the motor torque T. The evaluation functions are given by the drive conditions and the loss map, then the optimal trajectories are derived by solving the LMI optimization problem to minimize the evaluation functions. The effectiveness of the proposed method will be illustrated by means of some experiments.
