Abstract

The uncontrollable angles (UAs) in direct torque control (DTC) algorithm is an important issue through which the effects of voltage vectors (VEs) on the magnetic flux and the torque are accurately determined. In this paper, a unique analysis of UAs is performed at different operating conditions, including parameters variations in two different strategies: Direct torque and stator flux control (DTC_SC) and (DTC_RC). Values of Those angles were accurately determined for wide speed, stator and rotor variations, and load changes. In addition, a detailed numerical comparison was performed in terms of these angles in the two strategies mentioned above for each operating condition. The comprehensive comparison showed the superiority of the DTC_RC strategy over its DTC_SC counterpart, being the maximum values of UAs in DTC_RC were 8°, 33°, and 21° versus 15°, 45°, and 38° in DTC_RC strategy for the following operations: Variable speed with variable stator resistance, variable speed with variable stator and rotor resistances, variable speed with variable load, respectively. MATLAB/Simulink results of the contributed analysis and comparisons were accomplished and validated. In addition, DS1103-based experimental tests supported and verified the theoretical analysis.

直接转矩、定子磁通控制和转子磁通控制策略中的不可控角度比较分析：数值和实验研究

直接转矩控制（DTC）算法中的不可控角（UAs）是一个重要问题，通过它可以准确确定电压矢量（VE）对磁通和转矩的影响。本文对不同运行条件下的 UAs 进行了独特的分析，包括两种不同策略下的参数变化：直接转矩和定子磁通控制（DTC_SC）和（DTC_RC）。在宽转速、定子和转子变化以及负载变化的情况下，这些角度的值被精确确定。此外，还对上述两种策略在各种运行条件下的角度进行了详细的数值比较。综合比较结果表明，在下列运行条件下，DTC_RC 策略的 UA 最大值为 8°、33° 和 21°，而 DTC_RC 策略的 UA 最大值为 15°、45° 和 38°，DTC_RC 策略优于 DTC_SC 策略：分别为：定子电阻可变的变速、定子和转子电阻可变的变速、负载可变的变速。MATLAB/Simulink 的分析和比较结果得到了验证。此外，基于 DS1103 的实验测试支持并验证了理论分析。

期刊介绍： Prediction through modelling forms the basis of engineering design. The computational power at the fingertips of the professional engineer is increasing enormously and techniques for computer simulation are changing rapidly. Engineers need models which relate to their design area and which are adaptable to new design concepts. They also need efficient and friendly ways of presenting, viewing and transmitting the data associated with their models. The International Journal of Numerical Modelling: Electronic Networks, Devices and Fields provides a communication vehicle for numerical modelling methods and data preparation methods associated with electrical and electronic circuits and fields. It concentrates on numerical modelling rather than abstract numerical mathematics. Contributions on numerical modelling will cover the entire subject of electrical and electronic engineering. They will range from electrical distribution networks to integrated circuits on VLSI design, and from static electric and magnetic fields through microwaves to optical design. They will also include the use of electrical networks as a modelling medium.
