Abstract
This paper proposes a new current control method for energy-efficient and/or wide-speed-range drive of salient-pole permanent magnet synchronous motor. The proposed method is distinguished from conventional ones by the following features. 1) The original command is a signed current norm. 2) The exact d-axis and q-axis current commands that perform energy-efficient and/or wide-speed-range drive are analytically and simply determined from the singed current norm command. 3) For speed control mode, the system turns out to be nonlinear, but its stability can be guaranteed based on Popov's stability theorem. 4) It can be applied for a mode similar to torque control. 5) Current limitation can be carried out accurately but very simply. Concrete analytical d-axis and q-axis current commands are presented, which satisfy exactly one of three optimum current control codes such as maximum torque, maximum power factor, and voltage limitation. A design method for PI speed controller that guarantees system stability is also presented.
