碩士 === 國立勤益科技大學 === 電機工程系 === 104 === This paper presents a study of the chaos behavior of a DC-DC Buck Converter, where the input voltage Vin is changed to simulate and test Period 1, Period 2 and Chaos in the Buck circuit output phenomena. After deducing a dynamic system model using basic electronic circuit theory, the circuit simulation program Pspice was used to study the system status (induction, resistance and capacitance) of the fixed circuit structure. By changing the characteristics of the supplied voltage we were able to observe the Double Period phenomenon from the Phase-Plane figures obtained in the simulation. This finding will facilitate the control of systems-related output conditions. After deducing a dynamic system model using basic electronic circuit theory, the circuit simulation program Pspice and Matlab were used to study the system status (induction, resistance and capacitance) of the fixed circuit structure. By changing the characteristics of the supplied voltage we were able to observe the Period 1, Period 2 and Chaos phenomena from the Phase-Plane figures obtained in the simulation. A PID controller with IAE (integral absolute error) was used to control the Chaos phenomena and optimization of the controller was achieved using particle swarm optimization (PSO) and genetic algorithms (GA) as well as a fuzzy method. The simulations clearly showed that Period 1 to Period 2 and Chaos, and chaos can be controlled with a PID controller.
