The paper proposes a two input Switched Inductor Hybrid Buck-SEPIC DC-DC converter (TIHBSC) topology, for Low Voltage DC-grid (LVDG) applications. The projected topology is capable of providing extra bucking with one source. On account of excessive stepping down of the input dc voltage the converter uses additional energy storage components and hence it belongs to fifth order family. Power flow is...
In this paper a robust sliding mode controller is designed for DC-DC Ćuk converter. Sliding surface of the controller includes all of the system state variables. Hence, proposed controller has four-loop structure. Reference values of the state variables are calculated according to output voltage references using feedforward and feedback control loops. Designed controller can regulate output voltage...
Exact feedback linearization technique is applied to standard DC-DC buck converter using precise model of the system. Considering parasitic resistances of the inductor, capacitor and switches, averaged state space method is used to develop converter model. Hence, developed controller is able to regulate output voltage of the converter in a wide range of operation. Using the optimal control theory,...
The paper pertains to model validation and novel higher order sliding mode controller design for a nuclear research reactor. Sliding mode controllers for nuclear reactors were reported before but higher sliding mode controllers have added advantage of reduced chattering. The linear and nonlinear models of Pakistan Research Reactor-1 (PARR-1) have been tuned and validated with experimental data. These...
