AI Technical Summary
Technical Problem
Existing soft starters suffer from high losses when starting asynchronous motors, which limits the number of starts and the equipment cooling requirements.
Method used
A model prediction method is used to determine the triggering probability of the thyristor triggering the soft starter. The electrical and mechanical behavior is predicted by a transient motor model to avoid continuous triggering and steady-state assumptions and optimize the generation of trigger signals.
Benefits of technology
It reduces losses during startup, increases the number of startups, reduces cooling requirements, saves energy, and optimizes the motor acceleration process.

Abstract
本发明涉及一种用于借助软启动器(1)来启动和停止异步电机(4)的方法。该方法具有以下步骤：确定软启动器(1)的一个或多个晶闸管(2)在未来的计算时间点的可能的触发可能性；如果要执行对软启动器(1)的一个或多个晶闸管(2)的触发，则针对所确定的触发可能性预测电机行为；基于所预测的电机行为判定，是否应选择以及应选择哪个触发可能性；并且如果已经做出关于触发可能性的判定，则产生用于一个或多个晶闸管的一个或多个触发信号。
