Embodiment Construction
[0018] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can better understand the present invention.
[0019] Such as figure 1 As shown, it is a specific implementation of a highly reliable electric drive motor control method according to the present invention, and its specific implementation steps are:
[0020] (1) Collect the current i of the motor through the Hall sensor a i b , and then pass it through the abc / dq converter to get the actual current value i in the d-q coordinate system d and i q ;
[0021] (2) The position signal θ of the motor is collected by the position detector, and the position signal is differentiated to obtain the feedback speed signal rotor mechanical angular velocity ω r ;
[0022] (3) The given rotational speed ω r * with the feedback speed ω r Send it to the fuzzy PR regulator for processing, and get the given current i with str...
