Proceedings., 2001 4th IEEE International Conference on vol.1, pp.182-187It is well known that the efficiency of induction motor drives under partial load can be improved via manipulation of its field. Among the numerous loss-minimization schemes proposed previously, the scheme that uses motor power factor as the main control variable has the advantages of high sensitivity and ease of implementation. But the problem of how the optimal power factor commands can be generated is not well documented. In this paper, a scheme that uses power factor control with automatic measurement of the minimum-loss power factor commands is proposed. A fuzzy logic compensator is included in the controller to improve the accuracy of the generated commands. The scheme is simpl
