“…Note that, the voltage vector (control signal) given in (13) includes motor parameters, sampling period and reference current vector. Thus, it is able to cancel linear and nonlinear terms depending on the motor model, and the motor model has to be known very well to apply (13). However, not only motor parameters may vary during the operation, but there is also unmodeled dynamics such as inverter switching.…”

A discrete-time current controller is presented for the current loop of the permanent magnet synchronous motor drives. Firstly, the difference equations of current errors are obtained for constant reference values. Then, a dead-beat controller is designed to drive the dq-axes currents to the desired values. Discrete-time integral action with an anti-windup scheme is added to the dead-beat structure to achieve a better steadystate behaviour. In order to improve the transient properties of the controller, a current prediction scheme based on dead-beat structure is also introduced to the controller. Finally, the proposed controller is implemented through numerical simulations to illustrate the effectiveness for both transient and steady-state responses.

“…[4][5][6][7] combine different predictive method to regulate the current for PMSM. In [4], current ripple has been identified for getting the rate of current changing; [5] has designed a feed-forward controller with best tracking algorithm; a robust predict control has been gained in [6] utilizing a discrete current equation and introducing a weighting factor; [7] expounds a current deadbeat control with Luenberger observer. These researches emphasize the development of predictive method for current control, but ignore the nature of current change.…”

-This paper present a current predicting control method for PMSM (permanent magnet synchronous motor) to improve the tracking performance of stator current, which regards the current vector as the control target. Solving the model state equation in the static frame (α-β frame), the dynamic change of current vector will be gained as three independent terms. These change terms, which contain the prediction of current vector, are discretized and simplified by Taylor series expansion and used to get the voltage vector as the predictive control quantity. SVPWM will transform the control voltage to the switching signal of inverter, which is newly deduced for the current vector. Simulation and experiment results are given to testy and verify the performance of this method.

“…In [8]- [10] the "Straightforward Current Control" (SCC) scheme has been presented for the control of a DC machine as well as for the control of magnetic isotropic 3-phase synchronous machines (with L d = L q ), that delivers excellent control quality and high dynamics. At the same time it doesn't need any machine parameters, no machine model, no test pulses, no offline calculations or cost functions and the computational effort is comparatively little.…”
