This paper proposes a new control algorithm for a matrix converter (MC) induction motor drive system. First, a new switching strategy, which applies a back-propagation neural network to adjust a pseudo dc bus voltage, is proposed to reduce the current harmonics of the induction motor. Next, a two-degree-offreedom controller is proposed to improve the system performance. The controller design al...

In this article, an improved dc-link voltage regulation strategy is proposed for grid-connected converters applied in dc microgrids. For the inner loop of converter, a modulated direct power control employed to obtain two second-order linear time-invariant systems, which guarantees that closed-loop system globally exponentially stable. outer loop, sliding mode with load current sensor maintain ...

Accurate AFR control with TWC is a significant method to reduce the exhaust emission of SI engines. To follow the up to date model-based methodology in automotive industries, a virtual engine simulation platform was carried out to simulate a SGMW B15 engine based on enDYNA and improved by adding the AFR path dynamic models. Experiments and simulation results were compared for the model validati...

This research paper deals with the two closed loop speed control algorithms namely Six-Step and Direct Torque Control for Brushless DC Motor Drive. These two control techniques are critically evaluated for the performance comparison in terms of efficiency, steady state response and transient condition. The simulation models of the two controllers are developed in MATLAB/SIMULINK environment. Th...

In this paper, a new simulink model for a single phase induction motor is proposed using double field revolving theory. To maintain a constant fluid flow with a variation in the pressure head, drives like Fan load and Pump load are operated with closed loop speed control. For non linear loads, closed loop speed control is achieved using a neural network controller. A comparative study has been ...

We review and expand on the control of separated flows over flat plates and airfoils at low Reynolds numbers associated with micro air vehicles. Experimental observations of the steady-state and transient lift response to actuation, and its dependence on the actuator, airfoil geometry, and flow conditions are discussed and an attempt is made to unify them in terms of their excitation of periodi...

although lcl filters are used widely in the grid connected inverters to reduce high-orderharmonics, such a system increases system order and therefore sustainable design of closed-loopcontroller system will be complicated. recently, the single-loop control strategy has beensuggested for l or lc filter based grid-connected inverters. however, the use of single-loopcontrol directly in lcl filter-...
