Employee attitudes as a mediator between HRM and organizational performance [PDF]
, 2018 Attitude is a power that controls human behaviour. When employee Attitude is positive, it can give impact positive to organization performance. A proper human resource management (HRM) managed by organization, the employee attitude will be affected.

A voltage-source inverter for microgrid applications with an inner current control loop and an outer voltage control loop [PDF]
, 2009 Distributed generation (DG) units are commonly inter-faced to the grid by using voltage-source inverters (VSI’s). Extension of the control of these inverters allows to improve the power quality if the main power grid is disturbed or disconnected. In this

Benchmarking and optimisation of Simulink code using Real-Time Workshop and Embedded Coder for inverter and microgrid control applications [PDF]
, 2009 When creating software for a new power systems control or protection device, the use of auto-generated C code via MATLAB Simulink Real-Time Workshop and Embedded Coder toolboxes can be a sensible alternative to hand written C code.

IET Control Theory &Applications, Volume 19, Issue 1, January/December 2025.This paper explores robust optimal control for voltage regulation in DC microgrids with uncertain ZIP loads, addressing challenges through a two‐phase approach. Initially, robust control is applied using an undiscounted optimal control method, followed by a conversion to a data‐driven strategy with reinforcement learning.

IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.In this paper, a constrained FCS‐MPC based current controller is introduced for controlling shunt active power filters. In the proposed current controller, the objective function is same as used in the conventional FCS‐MPC and a switching frequency constraint is considered to reduce the average switching frequency. The results obtained from FPGA in the

A Novel Sliding Mode Control Strategy for VSG‐Based Inverters with Disturbance Estimation
IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.To enhance the robustness of the VSG‐based inverter control system against uncertain disturbances, this paper proposes a novel sliding mode control strategy consisting of two control layers for VSG‐based inverters based on disturbance estimation. ABSTRACT The interface inverter control system based on virtual synchronous generator (VSG) technology, has

Ripple‐Free Input Current Quadratic Converter Based on Watkin–Johnson Topology
IET Power Electronics, Volume 18, Issue 1, January/December 2025.This article proposes a power electronics converter capable of providing high voltage gain while keeping a high‐quality input current ripple. The technique for achieving the zero input current ripple at a selected duty cycle consists of extracting two inductor currents from the source in a counter‐phase manner.
