“…This can be justified that the FOC can synthesize a desired vector using the SVPWM technique to track the command, rather than apply discrete vectors in the MPC method. However, as a different control technique, the MPC method possesses some advantages over the FOC, such as fast dynamic response, flexibility of including objective constraints [33], [34].…”

Almost all of the existing reference vector based finite control set-model predictive control (FCS-MPC) methods for electric machines adopt the deadbeat control principle to directly obtain the reference vector. This paper proposes a computationally efficient control approach for a three phase permanent magnet synchronous motor (PMSM) based on indirect reference vector without using the deadbeat control. Instead of calculating a virtual reference vector in the traditional manner using deadbeat control, the reference vector is innovatively determined through two two-level bang-bang comparators. To improve the performance of the machine, the sampling period is subdivided into two equal time intervals and total 20 synthesized voltage vectors are obtained. Nevertheless, there is no need to evaluate all the 20 vectors by excluding the inappropriate vectors in advance using the reference vector based method, thus reducing the computation time. Moreover, with this proposed method, the complicated calculation of reference vector is avoided. Simulation and experimental results are presented to prove the effectiveness of the proposed method.

“…However, the dynamic and steady-state performance of deadbeat controller current loop will be affected by switching frequency of power devices, digital loop delay and parameter mismatch [8]. To solve the problem, some researchers have adjusted the sequence of voltage vector in each control cycle by using two adjacent active voltage-vectors with one zero-voltage-vector to improve the steady performance of stator current [9]. In [10][11][12][13], the disturbance observer, linear extended state observer and sliding mode observer have been used to eliminate the effect of the parameter mismatch.…”

When the speed of permanent magnet motor is relatively high, the fundamental frequency of stator voltage and current will rise. However, due to the limitation of switching frequency of power electronic devices, the switching times of power devices will be greatly reduced in a fundamental cycle of stator voltage. For the traditional control method with constant switching frequency mode, the control algorithm is executed only once in a carrier wave cycle, which will result in a low control frequency operating condition for the PMSM control system. At this time, the dynamic and steady-state control performance of stator current will be decreased. In response to above problem, this paper proposed a deadbeat predictive current control method based on oversampling scheme, which the core algorithm of current loop operated four times and updated the PWM duty twice in one switching cycle. The number of control times of the proposed method is greater than that of the conventional method when the conventional deadbeat method and the proposed method adopt the same switching cycle. Therefore, the control method does not increase the switching frequency of power devices, but improves the dynamic and stable performance of the system, especially under the highspeed condition.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.

This paper presents a fast predictive current trajectory strategy for permanent magnet synchronous motors (PMSMs) at voltage limit. The current hexagon obtained from the voltage hexagon of the inverter represents the region that the currents can reach in the next switching periond. The nearest avaliable current point to the reference is solved by geometrical method on the current plane. The output of the proposed algorithm is divided into four cases according to the position of the current points. The algorithm combines FCS-MPC and DPCC, has the merits of both method and also the fast dynamic at voltage limits. In order to increase the robustness against the parameter variations, moving horizon estimator is utilized. The rotor flux is eliminated in the algorithm and the voltage errors caused by resistance and inductance mismatches are compensated by the estimator. Several experiments are performed with DPCC, FCS-MPC and the predictive current trajectory control method. These comparisons validate the effectiveness of the proposed method.
