“…In this paper, due to the stator current signals from sensors will be not used for the control of the IM drive, so the IFOC technique receiving an only feedback signal from speed sensor called Feed-Forward FOC method will be applied to calculate and provide the reference currents to the current controller [6]. Here, the typical current controller uses the hysteresis modulation based on the comparison between reference stator currents and measured currents from sensors to generate the control pulse signals to the inverter's six switches [15].…”

A novel strategy based on the feed-forward field-oriented control (FOC) method is proposed for the Hysteresis Current technique to control the induction motor (IM) drive without current sensors (CSs). A control scheme is proposed to estimate stator currents from reference rotor flux, rotor flux angle, and state variables as a replacement for the feedback-signal of CSs used in the hysteresis current controller (HCC). Here the rotor flux angle component is extracted from the feed-forward FOC loop. MATLAB/Simulink is applied to implement the simulations under many different operating conditions. The simulation results demonstrated the feasibility of the proposed method to obtain high performance in controlling the IM drives without the current sensors.

Industrial Motor Drives require often required optimal speed and torque control. This work presents the implementation of a eld-oriented control (FOC) with a predictive current control strategy for an induction machine fed by a voltage source inverter. The FOC generates the stator current references for the predictive current controller, which selects the optimal switching state to be applied in the next sample period. The results from a Matlab/Simulink simulation validates the good dynamic performance of the proposed technique, making it a suitable strategy for induction machine control with two-level inverters.

“…In addition, when the inductor current and the minimum current command signal become equal, a set signal is generated, and the transistor is turned on. However, in the case of the valley current mode control method, in contrast to peak current mode control, sub-harmonic oscillation occurs when the duty cycle is less than 0.5 [23]. Figure 12 shows the current waveform of the valley current mode control formed according to the operation shown in Figure 11.…”

A wide-bandwidth current-controller is required for the fast charging and discharging of applications containing super capacitors. To accomplish this, peak current mode is generally used due to the speed of its response characteristics. On the other hand, peak current mode control must be provided with a slope compensation function to restrain sub-harmonic oscillations. However, if the controlled output voltage is varied, the slope must be changed accordingly. Nonetheless, it is not easy to change the slope for every change in output voltage. Another solution involves the slope being set at the maximum value, which results in a slow response. Therefore, in this paper, a hybrid mode controller was proposed that uses a peak current and a newly-specified valley current. Using the proposed hybrid mode control, sub-harmonic oscillation did not occur for duty cycles larger than 0.5 and response times were fast.
