The effects of two different inputs are decoupled to design the control topology for the system. The designed decoupled system is controlled with two isolated PI controllers to control the output voltage of the converter, and source current of the low voltage input. The developed controllers are analyzed in this work. The proposed control of the converter is implemented in the MATLAB-Simulink environment and the performances are analyzed. It is shown that the controller is able to maintain the reference output voltage in all operating conditions including 50% load increment in step.

One of the inputs is considered to be from PV, while the other one could be of any other nature. A linear control structure is developed to successfully integrate the PV and maintain the current supply from it, during (i) high load increment (50%) and (ii) variation in irradiance level of solar. The power supply to the variable load is found to be successful even by keeping the power supply level of the PV at a desired point. The implementation of the control in simulation is verifying the power control of the PV, without affecting the output voltage, during the considered operating conditions.

The perturb and observe (P&O)-based MPPT algorithm suffers from an inherent drift in case of an increment in solar irradiance. This drift is observed during the variation in duty cycle under rapid increment in solar irradiance. Modified drift avoidance P&O-based MPPT is developed to reject the drift effect by incorporating the current (dI) variation in the algorithm along with the power (dP) and voltage (dV) variation, respectively. The proposed novel drift avoidance P&O M-MPPT algorithm for boost converter is implemented and compared with the conventional P&O algorithm. The drift free performance is demonstrated for the proposed scheme with adaptive duty cycle (ΔD) technique. The simulation study is carried out in MATLAB/Simulink to predict the performance under variations in solar irradiance and load change. Furthermore, the experimental prototype is used to validate the simulation-based results. The proposed schemes are implemented using the dSPACE 1104. The steady state and transient results are showing the reduction in time to achieve the maximum power by the proposed technique successfully. The real time results are successfully validating the same theoretical findings in this work.

The considered converter is operated at a controlled output voltage, while supplied from two different levels of input voltages from two different sources. The proposed control is to ensure the faster time of responses during the variation in the dual references, the output voltage, and low‐voltage source current, simultaneously. The controller is developed by considering these two controlled variables, which are directly dependent on each other. This multivariable SMC is shown to perform successfully to maintain the controlled variables at their desired values despite the variation in the input voltage sources and also during perturbation in the load impedance. The stability analysis for the closed‐loop system is established with the Lyapunov method, which confirms that both of the controlled variables reach the desired stable band at the steady state. The control is implemented in the simulation environment for different operating conditions. A laboratory prototype is developed to implement the multivariable SMC. The experimental results successfully validate their simulated counterparts.
