当使用再生制动器降低电机速度时，旋转的机械能可以转换为再生电能。为了提高电机驱动系统的效率，应讨论电机的最佳再生和加速扭矩，以最大化再生电能并最小化加速所需能量。本文提出了一种鼠笼式感应电机（IM）最佳再生扭矩的设计方法，在给定扭矩幅值、运行时间和转速范围的约束条件下，通过变分法最大化再生电能。类似地，导出最佳加速扭矩，以最小化驱动所需的能量。通过模拟和实验证明了所提出方法的有效性。
When the motor speed is reduced by using a regenerative brake, the mechanical energy of rotation can be converted to the regenerative electric energy. In order to improve the efficiency of the motor drive systems, optimal regenerative and acceleration torque of the motor should be discussed in order to maximize the regenerative electric energy and to minimize the required energy for acceleration. This paper proposes a design methodology of an optimal regenerative torque for a squirrel-cage induction motor (IM) to maximize the regenerative electric energy by means of the variational method when the constraint conditions of torque amplitude, operation time period, and rotating speed range are given. Similarly, an optimal torque for acceleration is derived in order to minimize the required energy to drive. The effectiveness of the proposed methods are illustrated by both simulations and experiments.
