    摘要: It is well known that the efficiency of induction motor drives under partial load
    can be improved via manipulation of its field excitation. Among the numerous loss-
    minimization schemes previously proposed, the scheme that uses motor power factor
    as the main control variable has the advantages of high sensitivity and ease of
    implementation. But how the optimal power factor commands can be generated is not
    well documented. In this paper, a loss-minimization scheme that uses power factor
    control with automatic measurement of the minimum-loss power factor commands
    for vector-controlled induction motor drives is proposed. A fuzzy logic compensator
    is used in the controller to improve the accuracy of the command generator. The
    scheme is practical for implementation and does not require a priori knowledge of
    motor parameters. For verification, the loss-minimization controller was tuned according to the data from a set of commercially available induction servo motors ranging from 1 to 50 hp. The computed results shown that the errors between the calculated and the theoretical optimal power factor commands are all within 0.03. In
    addition, the experimental results have validated the effectiveness of this scheme in
    minimizing the motor operating losses at light loads.
