This paper presents the design and simulation of a DC-DC boost converter which uses wind energy as input source. Nowadays, wind is a type of renewable energy that is sustainable and clean compared to other alternative energy. Generally wind in Malaysia blows at variably low speed thus producing variably low input voltage as energy source. DC-DC boost converter can be used to increase the output voltage to a level suitable for domestic use. In this project, a closed-loop DC-DC boost converter circuit was designed and simulated using MATLAB SIMULINK based from a topological circuit. In the simulation, the circuit was tested with different low input voltage values to a setpoint of 240V. In order to improve the output voltage transient response, Fuzzy Logic controller is designed and implemented at the circuit to set the duty cycle of the switching device for the boost converter. The result has indicated better performance for boost DC-DC converter with FLC controller.

This paper proposes two stability criteria for polynomial fuzzy systems by applying minimum-type and maximum-type piecewise polynomial Lyapunov functions (PPLFs) respectively. Piecewise Lyapunov functions and polynomial Lyapunov functions (PLFs) have been utilized to the stability analysis for fuzzy-model-based (FMB) controlsystems to obtain relaxed results in literature. However, the minimum-type and maximum-type PPLFs have not been employed to analyze the stability of FMB controlsystems. Therefore, this paper applies the minimum-type and maximum-type PPLFs to the stability analysis of polynomial FMB controlsystems. Two relaxed stability criteria represented in terms of bilinear sum-of-squares (SOS) conditions are proposed. The proposed stability criteria are represented in terms of bilinear SOS conditions that cannot be directly solved by the mathematical tools of solving SOS optimization problem (e.g. SOSTOOLS and SOSOPT). Therefore, the path-following method that has been shown to be effective for the nonconvex bilinear matrix inequality problem is employed for solving the bilinear SOS problem of the proposed stability criteria. A numerical example is provided to demonstrate the relaxation of the proposed stability criteria.
