Summary: This article proposes a speed estimation scheme that combines the super-twisting algorithm with an FLL for speed-sensorless control in induction motor drives. The scheme improves reliability and reduces cost by eliminating the need for a speed sensor. It utilizes an adaptive second-order generalized integrator-FLL structure and a properly designed STA-QSG to improve speed estimation accuracy, and adopts a closed-loop flux observer for disturbance mitigation.

Summary: Nowadays, predictive current control (PCC) strategy is a promising option for electric drives due to its control flexibility, fast dynamic response, and structure without weighting factors. However, conventional control strategies lead to significant harmonics in stator current, resulting in steady state flux and torque ripple. To overcome these shortcomings, this study proposes a PCC strategy with the concept of virtual voltage vector (V3). The proposed V3PCC is more advanced in delay compensation and less parameter sensitive compared to the conventional approach. The performance of the proposed V3PCC is compared with a weighting factorless V3 based predictive flux control (PFC) scheme in induction motor (IM) drive, and the analysis is validated through simulations and experiments.

Summary: This article explores the possibility of connecting the engineering synthesis problems of frequency control systems for induction motor drives with the theory of identification based on AC electric machine equations. Experimental studies showed that there is no fundamental advantage in a drive with VC control over SC control in IMDs. Proposed nonlinear transfer functions for IMDs were found to be much more efficient than traditional VC, leading to more accurate identification of dynamics and higher efficiency.

Summary: In this paper, a discussion on unipolar vector-controlled speed sensorless SRM-drive is highlighted. A new MRAS-based scheme is proposed to improve the performance of speed-sensorless vector controlled SRM drive. The proposed scheme does not require the measured value of stator resistance and is insensitive to variations in stator resistance. It is also less sensitive to the inductance related parameter 'Lav' compared to other speed estimators. The proposed scheme is stable and suitable for aircraft propulsion applications.

Summary: An enhanced magnetizing current-oriented low-frequency ride-through method is proposed for speed-sensorless induction motor drives to ensure observability of the rotor speed. Adaptive changes in the magnetizing current reference are generated to maintain the speed observable margin, avoiding noise caused by direct rotor flux reference calculation. The feedback matrix is employed to narrow the unstable regenerating region and enlarge the observable margin.

Summary: This article proposes a second-order terminal sliding-mode (SO-TSM) speed controller with nonlinear control gain for high-end industrial application of induction motors. The method introduces a convergence trajectory without speed overshoot by designing a SO-TSM manifold, and compensates external disturbance with an integral term control law using the antiwindup mechanism. The torque rejection capability of the method is represented by the gain value of the integral term, and the experimental results demonstrate its strong torque rejection capability.

Summary: As the global population grows, the demand for food, energy, and water will increase significantly. However, limited land availability and competition for solar resources pose challenges to resource generation technologies. In the United States, both agriculture and solar energy production have adopted densification schemes to improve yields and energy output per unit of land. This research proposes an Agrivoltaic food and energy coproduction architecture that optimizes power generation while maintaining crop productivity by implementing ideal anti-tracking during critical growth periods. This technology offers a viable pathway for widespread solar implementation throughout the contiguous United States.
