| Abstract: | The optimal issue on turn-on and turn-off angle of switched reluctance motor was researched with the maximum torque/ampere ratio as the optimal index.Firstly,on the basis of analyzing the principle of obtaining the optimal turn-off angle,put forward a heuristic search algorithm to look for the mapping relationship between speed(n) together with torque(T) and the optimal turn-off angle(θoptoff).Secondly,established BP neural network model to express this relationship.Finally,developed a experimental system based on the model,which shows that: the torque/ampere ratio optimized by neural network is much bigger than that of not optimized,thus verifies the feasibility and superiority of this method. |
