“…When the motor parameters are not accurate, the control performance will be affected. As for future works, the proposed OST-M2PC with an actual parameter disturbance observer such as luenberger [28], ESO [29], [30] or SMO [31] based approach will be used to improve robust ability of OST-M2PC.…”

Conventional finite control set model predictive control (FCS-MPC) presents high computational burden especially in three-level neutral point clamped (NPC) converters. This paper proposes a low-complexity optimal switching time modulated model predictive control (OST-M2PC) method for three-level NPC converter. In the proposed OST-M2PC method, the optimal switching time is calculated using a cost function. Compared to conventional FCS-MPC, the proposed OST-M2PC method has a fixed switching frequency as well as better power quality. The proposed OST-M2PC can operate at a 20kHz sampling frequency, reducing the computational burden of the processor. Simulation and experimental results validate the operation of the proposed method. Index Terms-Finite control set model predictive control (FCS-MPC), modulated model predictive control (M2PC), permanent magnet synchronous motor (PMSM), optimal switching time modulated model predictive control (OST-M2PC).

This paper presents a control scheme for a recently reported aircraft advanced power generation center (APGC) during postfault operation conditions. Within the APGC, two electrical generators extract power from two separate engine shafts and supply electrical power to a common HVDC bus through their dedicated main AC/DC power converters. An extra back-to-back (BTB) converter is also used to connect the ac terminals of the two generators. This architecture provides merits of fault tolerance capabilities of the APGC. In the case of main AC/DC power converter failure, the system can be reconfigured and the BTB converter provides an extra power flow path from the generators to the HVDC bus. This ensures electrical power generation capabilities onboard. The paper discusses in detail the control of the APGC under fault conditions with one main AC/DC converter failure. A seamless transition scheme from normal operation to postfault conditions is proposed using a voltage command initialization technique within the BTB converter. Both experimental and simulation results have verified the fault tolerance improvement and control performances of the APGC.

“…However, due to the strong external disturbance and model uncertainty in complex working conditions, the PI controller cannot meet the practical requirements for some high performance applications. With the development of control theory and microcomputer technology, the nonlinear control strategies have been applied to PMSM drives, such as sliding model control [3][4], model predictive control [5], backstepping control [6], active disturbance rejection control [7], repetitive learning control [8], and intelligent control [9]. Among these methods, backstepping control, as a nonlinear recursive design method, is proposed in 1990s [10].…”

“…As is known, sliding mode control (SMC) has been proved to be a potentially useful approach in industrial applications, such as actuator [21], robot [22][23] and PMSM [3][4]. Many advanced sliding mode control methods are widely used in motor drive, such as fractional order sliding mode control [24], terminal sliding mode control [25] and integral sliding mode control [26].…”

Aiming at the speed regulation problem of permanent magnet synchronous motor (PMSM) drives, a novel backstepping nonsingular terminal sliding mode control (BNTSMC) method with finitetime disturbance observer (FTDO) is proposed. In order to ensure excellent tracking and anti-disturbance performance, the backstepping nonsingular terminal sliding mode speed controller based on equivalent motor model and the recursive principle is designed for PMSM. The benefits of this approach are that the controller has asymptotic stability based on backstepping design, finite-time convergence, and strong robustness for the matched disturbance based on sliding mode control. Then, to further improve the antidisturbance performance, a finite-time disturbance observer is designed, and it is used to estimate the mismatched external disturbance in motor drive system. The stability of the system is also proved with Lyapunov criterion. Finally, the experimental results show that the proposed method has the advantages of fast convergence and strong robustness against parameter variations and external disturbance.INDEX TERMS PMSM drive, backstepping nonsingular terminal sliding mode control (BNTSMC), finitetime disturbance observer (FTDO).
