TL;DR: An efficient compensator is proposed that introduces one degree–of–freedom to the direct–axis current controller in synchronous reference frame, which eliminates the adverse impact of DVI function on converter stability.

TL;DR: The proposed controller is an online and non-model-based scheme which properly reduces the system order through a set of coherent areas to provide proper damping performances of inter-area oscillations.

TL;DR: In this article, the root'locus curve of the system for stability and chaos analysis is derived by changing the controller parameters in constant speed control, and the largest Lyapunov's exponent is determined numerically.

TL;DR: The proposed topology is designed in a way that the mosfet works at the significantly lower switching and conduction losses in compared with conventional LED drivers, and improves the overall efficiency by decreasing power losses in other main elements of the driver, including inductance and diode.

TL;DR: In this article, the existence of chaotic behavior in vector control drives of induction machines is investigated, and a method for avoiding this phenomenon is proposed, and the bounds of different parameters to avoid chaotic response can be determined.
