This paper surveys the literature of the brushless DC motor speed control techniques. The paper should prove useful to both researchers as well as practising engineers as a signpost to the current state of the art. Based on the review some further studies are suggested.

Model predictive control (MPC) based methods are gaining more and more attention in power converters and electrical drives. Nevertheless, high computational burden of MPC is an obstacle for its application, especially when the prediction horizon increases extends. At the same time, increasing the prediction horizon leads to a superior response. In this paper, a long horizon MPC is proposed to c...

In this paper, a new method is proposed for the speed control of a three-phase current forced synchronous machine drive. This metohd is based on the use of an approximate constant commutation safety margin angle in the output thyristor bridge of the drive system as well as on the compenastion of stator magnetization reaction. The commutation process in the output converter of the machine driv...

This paper presents a coupling estimation based decoupled current vector control scheme for of Dual Three Phase (DTP) Surface Permanent Magnet Synchronous Motor (SPMSM) drive with two micro units (MCUs), to solve its inherent magnetic issue. Aiming an enhanced fault tolerance, the SPMSM utilized is redundant and modular system composed subsystems in terms three-phase inverters, sensing, control...

Hysteresis current control method is vastly used in PWM inverters because of simplicity in performance, fast control response and good ability in limiting peak current. However, switching frequency in hysteresis current control method with fixed bandwidth has large variation during a cycle and therefore causes non-optimal current ripple generation in output current. One of basic problems in imp...

In this paper, we propose three advanced digital predictive current-mode control (DPCC) algorithms based on a simplified estimation method of duty cycle lost time for asymmetric half-bridge (AHB) LED constant-current driver. They are the peak current mode control(DPPCC) algorithm leading-edge modulation, quasi-valley control(DPqVCC) trailing-edge and quasi-average control(DPqACC) double-edge mo...
