This paper presents an active noise isolation (ANI) based control algorithm for single-phase single-stage solar photovoltaic (SPV) system connected to the AC grid. An ANI based algorithm used to control a voltage source inverter (VSI) which performs load compensation, harmonics mitigation, feeding solar power into the AC grid and many other power qualities issues. The proposed system comprises SPV...
This paper deals with vector control of grid-connected converter under unbalance grid conditions using single AC side current sensor. DDSRF based decoupling technique is used for decoupling of grid voltage and enhanced DDSRF is used for decoupling of grid current in the revolving d+−q+ and d−−q− frames. In the presented method, the stationary α-axis current is simply proportional to sensed r-phase...
The accurate rotor position tracking and speed control of Hybrid Stepping Motor requires complete state information for investigation. In this paper, rotor position tracking is addressed from the framework of Lyapunov-based control and passivity based control method. In the former control scheme, nonlinear estimation technique employs a nonlinear observer along with Lyapunov-controller to estimate...
This paper aims to develop an innovative direct torque control (DTC) for an induction motor (IM) drive based on model prediction (MP). An effective methodology for the optimum selection of weighting factor is proposed, based on the evaluation of ripple behavior. A sensorless speed estimation technique utilizing the predictive nature of proposed MP DTC is adopted. Firstly, the paper introduces a detailed...
