摘要

在考虑转子磁链磁饱和的情况下,提出了磁场定向电机单步速度响应的时间最优控制方案。该方案基于时间最优控制问题的解析解。尽管磁场减弱,但对于低噪声或高效率的驱动器,仍然可以实现高速响应。最优控制是利用间接面向场控制系统中包含的查找表来实现的。讨论了转子转速和加减速变化率约束等问题。与其他控制策略相比,描述了时间最优控制方案的优点

Implementation of a time-optimal single-step velocity response control scheme of field oriented induction machines considering saturation of flux
A time-optimal single-step velocity response control scheme for field-oriented induction machines is implemented, taking magnetic saturation of the rotor flux into account. The scheme is based on the analytical solutions of the time-optimal control problem. High velocity response is achieved, despite field-weakening, for low acoustic noise or high efficiency drives. Optimal control is realized by using a lookup table that is included in the indirect field-oriented control system. The problems of rotor speed and constraint on rate of change of acceleration or deceleration are also discussed. The merit of the time-optimal control scheme as compared with other control strategies is described.<>
