BFO control tuning of a PMSM high speed drive

In this paper a new online adjustable adaptive field weakening, based on the Bacterial foraging optimization algorithms is presented. In the traction and electric vehicle applications, the high speed mode is important. Effectively the Field weakening technique is needed. However in the environment supported by the system, many parameters can influence on the global control technique, like temperature, dust or vibration. Well, to resolve these problems a new adaptive control technique, support this variations, is presented in this paper.
