“…1). This coordinate system is called the "d-q" coordinate system [32], where the real axis is called the "direct-axis" (shortly: "d-axis") and the imaginary axis is called the "quadrature-axis" (shortly: "q-axis"). The direct-and the quadrature-axis components of the stator flux vector are as follows [33]:…”

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.

“…The throttling nozzle diameter D 1 was 5 cm, the diameter of the nozzle of the bypass duct D 2 was 7 cm and the distance between the nozzles l 13 was 2 cm. [8], [9]. The measurements carried out using the depicted jet engine were primarily aimed at identifying the correlation between the engine thrust F e and the input power P. Also, the current I of the engine was measured at each value of the input power, as well as the value of voltage U at engine terminals.…”
