“…The excellent dynamic torque-control capabilities of traditional DTC are well known in the literature for permanent magnet synchronous motors and for other motor types as well [4][5][6][7][8][9].

DTC-SVM solves these problems, as it uses fixed switching frequency and the torque-ripple is significantly reduced compared to DTC, while the dynamics of the torque-control is essentially identical to that of traditional DTC [13][14][15].…”

Direct torque control with space vector modulation (DTC-SVM IntroductionDirect torque control with space vector modulation is a modification of the original direct torque control (DTC) method [1][2][3]. The excellent dynamic torque-control capabilities of traditional DTC are well known in the literature for permanent magnet synchronous motors and for other motor types as well [4][5][6][7][8][9]. However, there are serious disadvantages and among them the most important are: varying switching frequency and the excessive amount of torque-ripple generated [10][11][12]. DTC-SVM solves these problems, as it uses fixed switching frequency and the torque-ripple is significantly reduced compared to DTC, while the dynamics of the torque-control is essentially identical to that of traditional DTC [13][14][15]. Therefore, DTC-SVM is currently considered as one of the most promising alternatives of the nowadays widely used field-oriented control [16,17].DTC-SVM was introduced in [1][2][3]. These publications highlighted the main advantages of DTC-SVM. Since then many investigations have been carried out for this method. Special applications requiring high dynamic performance, excellent efficiency and high precision have been examined such as artillery speed servo systems [18], electric vehicles [19], electric pitch servo systems for wind generators [20]. Also, asymmetric permanent magnet synchronous machines have been investigated and special solutions have been invented for these machines [21]. In order to improve the performance of DTC-SVM several modifications have been developed. Most of the modifications aim at reducing the torque-ripple, increasing the dynamic performance and the efficiency of the method [22][23][24][25][26][27][28]. Sensorless methods using extended Kalman-filter have also been invented [29].However, the overload-capabilities of DTC-SVM and its stability during overloading have not been investigated yet. This article deals with these issues and suggests a modified DTC-SVM (MDTC-SVM) method which has significantly improved overload-capabilities and it is stable during overloading.

“…It is well known that there are several approximation methods for differential equations [6]. In the field of motor control, forward Euler approximation method is widely used to obtain the discrete motor prediction model due to its simplicity and low computational burden for single-step prediction applications [7][8][9]. In Reference [10], a modified Euler integration method was adopted to achieve higher model accuracy, which actually transformed the implicit Tustin approximation to an explicit one by combining with forward Euler approximation.…”

Finite-control-set model predictive current control (FCS-MPCC) has been widely investigated in the field of motor control. When the discrete motor prediction model is not obtained accurately, prediction error often occurs, which can result in improper determinations of optimal voltage vectors and can further affect the control performance of motor systems. However, papers evaluating the motor control performance employing FCS-MPCC rarely consider prediction error and its utilization to weaken the influence of inaccurate prediction model. This paper investigates in depth the prediction error caused by three influencing factors from the perspective of model accuracy-discretization method, prediction stepsize, and parameter mismatch. Firstly, the evaluation index, prediction error, is defined and its formulas considering the above three factors are derived based on interior permanent magnet synchronous motor (IPMSM). Then, the theoretical analysis of prediction error is provided. Finally, experimental results of an IPMSM drive system are presented to verify and complement the theoretical analysis. Both the theoretical analysis and experimental results fully elaborate the prediction error, which can offer practical guidelines for the evaluation and improvement of motor control performance, especially for FCS-MPCC in IPMSM applications.
