The Predictive Control Method is compared with Perturb and Observe and Fuzzy Model Predictive Control via simulation results using Matlab and experimental results.CircuitLab is an in-browser schematic capture and circuit simulation software tool to help you rapidly design and analyze analog and digital electronics systems.

It is shown that the predictive control method in ideal system has a better performance in both faster dynamic and steady state response under rapidly changing atmospheric conditions. The Cuk converter has fewer active elements compared to ultra-step-up boost converter and the extra sensors are eliminated. In this article, a Cuk converter is analyzed using the predictive control and Fuzzy Model Predictive Control (FMPC) method to achieve MPPT in photovoltaic systems. Another disadvantage of MPC is that the actual values of the system elements either are not available or can change over time. It means that if the system equations are written according to the real, actual conditions, the formulations become very complicated and take up a large amount of microprocessor time and memory. In MPC, the system equations must be ideally formulated. By using the predictive equations, the additional sensors are removed. The current is predicted using the system model and the optimal operating point is determined via a certain cost function. The main purpose of this control is to improve the maximum power point tracking using predictive error in Perturb and Observe method step.

Predictive control is simple in both method and implementation aspects. Approval of the thesis: DESIGN AND IMPLEMENTATION OF COUPLED INDUCTOR CUK CONVERTER OPERATING IN CONTINUOUS CONDUCTION MODE submitted by MUSTAFA TUFAN AYHAN in partial fulfillment of the requirements for the degree of Master of Science in Electrical and Electronics Engineering Department, Middle East Technical University by, Prof. Different solutions have been recently proposed in numerous papers. Maximum Power Point Tracking (MPPT) has an important role in studying and implementing photovoltaic systems. This is an open access article under the CC BY-SA license. Finally, the performance of the regulated PV system is tested using both simulations and experiments. Therefore, this paper proposes a highperformance sliding-mode controller for PV systems based onД†uk converters, which regulates the PV voltage in agreement with the commands imposed by a MPPT algorithm, rejecting both load and environmental perturbations, and ensuring global stability for real operation conditions. However, PV systems based onД†uk converters usually do not provide formal proofs of global stability under realistic conditions, which makes impossible to ensure a safe operation of the PV installation. Because its two inductor structure,Д†uk converters have continuous input and output currents, which reduce the additional filtering elements usually required for interfacing dc/dc converter topologies. The wide range of step-up and step-down input-output voltage characteristic of thГ© Cuk converter makes it a good candidate to interface photovoltaic arrays in both classical and distributed maximum power point tracking systems. The Cuk converter is a step-down/step-up. Furthermore, it is confirmed that the output voltage ripple frequency is always double of the input line frequency, 50 Hz and the output voltage ripple is always lower than the maximum input voltage ripple. PECS uses a schematic-based circuit editor and features its own plotting tool, PECSPLOT. The experimental results show that the THD current is reduced to 4.5% from 61.3% and the output voltage ripple is reduced to 7 V from 18 V after parameters optimization are realized. A 65 W PFC Cuk converter prototype is developed and experimentally tested to confirm the parameters design optimization principle. In addition, the selection of high output capacitance will minimize the output voltage ripple significantly. The principle of the parameters design optimization is based on the balancing energy compensation between the input capacitor and output inductor for minimization of THD current. 3 Circuit Operation of BL PFC Cuk Converter fed EV Charger (a) Mode P-I (b) Mode P-II (c) Mode P-III Mode P-II starts when the polarity of the capacitor C 1 reverses as the gate pulses to the switch are made OFF at the instant t 2. Nevertheless, the ranges of duty cycle for buck and boost operations are 0
