A rule-based acceleration control scheme for an induction motor

This paper presents a rule-based acceleration control scheme which aims to give an inverter-fed induction motor excellent dynamic performance. In every time interval of the control process, the acceleration increments produced by two different voltage vectors are compared, yielding one optimum stator voltage vector which is selected and retained. The online inference control is built using a rule-based system and some heuristic knowledge about the relationship between the motor voltage and acceleration. Because integral calculation and motor parameters are not involved, the new controller has no accumulation error of integral as in the conventional vector control schemes and it can be used for different induction motors without modification
