Vector-controlled induction electrical drives are one of the main types of modern AC electrical drives due to the well-known advantages of induction motors. Recent years have been marked by a renewed interest in the further development of IM control methods due to the existing limitations on the use of rare-earth materials in the manufacturing of permanent magnets synchronous motors. A full-scale study of the dynamic and static characteristics of induction motors field-oriented control systems, as well as their comparative analysis with existing analogues, is an important and mandatory stage in the modern AC electrical drives design. Since IM field-oriented control systems are essentially nonlinear multi-dimensional systems with a partially measured state-space vector, there are no general standard methods for design and analysis, including the dynamic and static characteristics investigation under parametric disturbances. Control algorithms are designed based on various conceptual approaches, and the same applies to the research methods of the closed-loop systems robustness properties. The literature offers a large number of both theoretically proven and practical solutions, which use different sets of tests and different criteria for evaluating effectiveness, making their comparative analysis virtually impossible. A systematic approach to comparative testing and analysis of control quality and robustness indicators of field-oriented control systems under disturbance conditions in the form of active rotor resistance variations is proposed. It can be considered as a component of a general testing platform for vector-controlled electrical drives. A comparative study of a class of systems with indirect and direct field orientation, based on the concept of improved (robustified) vector control of IM drives, demonstrates a significant increase in the robustness properties of the flux vector regulation, both in terms of amplitude and angular position. In turn, it compensates for the negative impact of active rotor resistance variations on dynamic control processes and the efficiency of electromechanical energy conversion processes.
