TL;DR: The importance of this new control scheme is that it can compensate the uncertainty in a very effective way and it also avoids over compensation and renders modest control effort.

TL;DR: A new sensorless control based on the robust observer, nonorthogonal phase-locked loop (PLL), and variable phase delay compensation is proposed, which can guarantee the medium- and high-speed sensorless Control performance for the FTPMSM even in the phase open-circuit and short-circuits fault conditions.

TL;DR: A control scheme is proposed to render a twofold performance: guaranteed and optimal, based on a very general Lyapunov function, to cast both the descriptions of the uncertainty and desired performance index into a fuzzy framework.

TL;DR: This paper designs a class of robust constraint-following controls free from mismatched uncertainty and only based on matched uncertainty, and shows that the proposed robust controls guarantee uniform boundedness and uniform ultimate boundedness for underactuated systems.

TL;DR: The simulation and experimental results show that the FTPMSM system with the proposed sensorless control has excellent speed control performance, accurate rotor position/speed estimation, and great system robustness in the presence of various uncertainties, which is able to guarantee the system performance both in normal condition and in fault condition.
