In this paper, one-cycle control (OCC), as a constant-frequency PWM control strategy for current control of a six-switch brushless dc (BLDC) motor drive is investigated. Developed current regulator is a unified controller and PWM modulator. Employing the one-cycle control strategy, decreases the torque ripple resulted from the conventional hysteresis current controllers and therefore, the vibra...

when power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. sssc is a facts device con...

For the permanent magnet linear synchronous motor (PMLSM) applied in the high-precision equipment, motor control system should have characteristics of high dynamic response and strong robustness. Predictive current control is an effective method to improve the dynamic response of the system, but it requires accurate motor parameters. This paper presents an improved deadbeat predictive current c...

Arm current control is a promising candidate for modular multilevel converter (MMC) due to it can effectively regulate ac-side and the ac component of circulating currents simultaneously. The conventional arm controller designed in frequency domain based on classical theory have design separate each reference signal. As result, structure complicated. And limited by bandwidth compound controller...

This work presents a novel optimization method for the implementation of finite-state model-based predictive current controllers in electrical drives. The proposal avoids usual exhaustive search to find control action, reducing computational burden. is based on physical considerations power converter voltage vectors and easy implement digital signal processors. applied five-phase induction mach...
