Summary: This research article introduces a solar photovoltaic (SPV) fed 3-phase induction motor (IM) drive for water pumping applications. The system uses a three-phase four-switch voltage source inverter (FSVSI) which has advantages such as fewer switches, reduced gate driver circuits, less switching losses, and lower cost compared to orthodox six-switch voltage source inverters (SVSI). The system also incorporates power conditioning units, a boost converter, and the P&O MPPT algorithm to maximize the power output from the SPV system. The operation of the SPV-fed FSVSI IM is validated through both simulation in MATLAB and experimental testing using DSPACE DS-1104.

Summary: A disturbance estimation and rejection technique based on the improved active disturbance rejection control (IADRC) approach is proposed and verified on a ground two-wheel differential drive mobile robot. The IADRC is adopted to eliminate the effect of system uncertainties and external torque disturbance on both wheels. A novel nonlinear sliding mode extended state observer (NSMESO) is used to observe and cancel the generalized disturbance in real-time. Numerical simulations show a significant reduction in the ITAE index for both wheels, validating the efficacy of the proposed dynamic speed controller in damping the chattering phenomena and providing high insusceptibility to torque disturbance.

Summary: This article proposes a distributed intelligent secondary control approach for power electronic-based ac microgrid using brain emotional learning-based intelligent controller (BELBIC). The BELBIC controller is capable of quickly learning and handling the complexity, nonlinearity, and uncertainty of the microgrid. It is fully model-free, regulating voltage amplitude and frequency deviations without prior knowledge of the system model and parameters. The proposed approach ensures low steady-state variations with higher bandwidth and accurate power-sharing through the droop mechanism. Additionally, primary control is achieved using robust finite control set-model predictive control and droop control to optimize the system's frequency bandwidth and power-sharing among distributed generations. Experimental tests conducted on a hardware-in-the-loop testbed validate the effectiveness of the proposed control strategy for various scenarios.

Summary: This paper proposes a novel method of capacitor condition monitoring for the dc-link of power converters used in distributed energy resources systems. The method injects an intermittent noncharacteristic signal into the dc-link to estimate the equivalent series resistance (ESR) and capacitance (C) of the capacitors. A real-time stationary discrete wavelet packet transform (RT-SDWPT) is used for capacitor parameter estimations. Experimental results from a microgrid laboratory setup demonstrate the effectiveness and feasibility of the proposed method.
