“…Another solution to avoid the exhausted tuning of weighting factor is to eliminate it. In [15] and [16], multiobjective cost function was decomposed into several singleobjective cost functions. Then, each single-objective cost function was ranked.…”

“…The one has the minimum sum of the rankings was selected as the optimal voltage vector. The weighting factor was not necessary in [15], [16], but the computation burden was still heavy. The weighting factor in [17]- [20] was eliminated by converting the control of two objects with different units into the control of two objects with same unit, and the computation burden was effectively reduced.…”

An Improved Parallel Predictive Torque Control for Permanent Magnet Synchronous Motor

A predictive torque control strategy with parallel structure (P-PTC) was recently proposed to overcome the tedious tuning of weighting factor in the conventional predictive torque control (C-PTC). However, P-PTC still has some problems, such as the introduction of other parameters to be tuned and the lack of theoretical support, et al. To solve the above problems, an improved P-PTC without any extra parameters tuning (IP-PTC) is proposed for permanent magnet synchronous motor (PMSM). Firstly, two parallel cost functions are respectively constructed to select three voltage vectors that have the best control effect on electromagnetic torque and stator flux to form two new finite control sets (FCSs). Secondly, three different cases are divided according to the intersection number of these two FSCs. Finally, the corresponding optimal voltage vector selection scheme is proposed for these three cases. C-PTC, P-PTC and the proposed IP-PTC are studied through theory and experiments. The results show that when compared with C-PTC and P-PTC, the proposed IP-PTC has neither weighting factor nor any extra parameters, and it is well supported by theory. Furthermore, the proposed IP-PTC has the best static and dynamic performance among the three.INDEX TERMS predictive torque control (PTC), permanent magnet synchronous motor (PMSM), weighting factor, parallel

“…However, there is a weight coefficient between torque and flux, so it is difficult to obtain the optimal control performance. To solve this problem, an MPTC strategy for open winding induction motor is proposed to eliminate the weight coefficient [19], [20], which can achieve better torque and flux control performance. However, this strategy requires a large amount of computation.…”

The structure of open-winding motor fed by the dual-inverter can increase the winding terminal voltage of the primary permanent-magnet linear motor (PPMLM). So, it is an effective method to improve the thrust performance of the PPMLM. Based on the detailed derivation of the mathematical model of the open-winding PPMLM and the in-depth analysis of the space voltage vector distribution characteristics of the dual-inverter, a deadbeat two-vector model predictive current control (MPCC) model is proposed in this paper. First, the optimal vector of the inverter 1 is determined by judging the position of the large sector. Second, two optimal vectors of the inverter 2 is determined by judging the position of the small sector. Finally, the duty cycle of the two optimal vectors of the inverter 2 is calculated to realize the proposed deadbeat two-vector MPCC algorithm. Compared with the traditional model predictive torque control (MPTC) and MPCC strategies, the proposed algorithm has the advantages of lower current harmonics (lower 34 % and 44 % under rated conditions, respectively) and better thrust performance (higher 77 % and 61 % under rated conditions, respectively) as well as lower computational complexity. Simulation and experimental results show that the proposed two-vector MPCC has good steady-state and dynamic performances, which can reduce the current harmonics and thrust ripple, and thus improve the motor drive performance compared with the traditional method.

“…MPC strategies have received wide attention in research communities due to merits of high flexibility, a simple concept, and easy inclusion of non‐linearities and constraints [1–5]. In recent years, MPC has been applied in the field of power electronic control [6–10]. Some scholars have also tried to introduce the approach into direct torque control (DTC) with some success.…”

Tedious adjustment of the weighting factor restricts the wide application of conventional model predictive torque control (MPTC) for induction motors (IMs) in practice. To solve this problem, this study introduces a new variable R (reactive torque) to control the flux of IM, which is the dual of torque T, with radial orientation and in relation to reactive power. Then, a novel MPTC strategy based on variable R and torque T is proposed and named RT-MPC. Compared with conventional MPTC, RT-MPC uses a pair of variables with the same dimensions and time scales instead of the torque and flux amplitude in MPTC. This approach eliminates the weighting factor of the cost function, unifies the time scales of control variables, and avoids prediction of rotor flux at the (k + 2) instant. Simulation and experimental results show that RT-MPC can avoid the weighting factor, reduce switching frequency, and reduce control complexity. RT-MPC can also maintain excellent dynamic and steadystate performance similar to conventional MPTC. Hence, the proposed method is expected to be more practical.
