Analysis on the developmental trend of adaptive control theory and the applications on electric machine control

Adaptive control of the research object is the uncertainty of the system to a certain extent, so-called “uncertainty” here refers to describe the mathematical model of controlled object and its environment is not entirely sure, including some unknown factors and random factors. Adaptive control and regular feedback control and optimal control, is also a kind of control method based on mathematical model, the difference is adaptive control is based on a priori knowledge about the model and the disturbance is less, the need to constantly in the process of the operation of the system to extract the information on the model, the model gradually improve. This topic in the existing research for adaptive control mode on the basis of the specific application scenario for the related algorithm used in motor control, motor control is to point to, for the start of the motor, speed control, operation, slow down and stop. According to the use of different motor types and have different requirements and purpose. For motor, motor control, to achieve quick start motor, fast response, high efficiency, high output torque and overload.
