In this paper, the two-input fuzzy logic controller (FLC) for buck boost converter output-voltage regulation is proposed by using LabVIEW. Here the output voltage has been used as a closed loop feedback to determine the output error (e) and the change in error (Δe) as two inputs to the controller. The elements of the buck boost converter as inductance and capacitor have been selected to insure continuous operating mode (CCM) and low output voltage ripple. The experimental results show that the FLC has a good output voltage response compared with PID controller response. This research has successfully showed that LabVIEW and Fuzzy Logic controller can be applied to develop a system for selecting the modes of controller.

In the proposed topology, the MosFETs are driven by phase-shifted PWM signals, where both phase angle and duty cycle are controlled variables. The power flow between the two inputs is controlled through the duty cycle, whereas the output voltage can be regulated effectively through the phase-shift. The primary side MOSFETs can achieve zero-voltage switching (ZVS) operation without additional circuitry. Additionally, due to the ac output inductor, the secondary side diodes can operate under zero current switching (ZCS) conditions. In this work, the operation principles of the converter are analyzed and the critical design considerations are discussed.. Moreover, the derived mathematical models are validated by simulation and measurements. In order to verify the validity of the theoretical analysis, design and power decoupling control scheme, a prototype is constructed and tested under the various modes, depending on the availability of the renewable energy source and the load consumption.

The classical controllers like PI and PID controllers have so many limitations. These controllers provide better performance only at particular operating range. The specific control problems associated with the plant operations severely limit the performance of conventional controllers. The increasing complexity of plant operations together with tougher environmental regulations, rigorous safety codes and rapidly changing economic situations demand the need for more sophisticated process controllers. Model predictive control (MPC) is an important branch of automatic control theory. MPC refers to a class of control algorithms in which a process model is used to predict and optimize the process performance. In this project, pressure in a pressure process station is to be controlled using model predictive control in real time. The pressure process station ...
