This work presents a FPGA-implemented real-time simulation of a full-bridge RL load inverter, using Sinusoidal Pulse Width Modulation (SPWM). The selected methodology consist on obtaining the mathematical model of the full-bridge RL load inverter based on state equations for every switching state of the converter and then solving the set of state equations(More)
This paper presents the real-time simulation of a Buck converter designed to create an educational platform. The real-time simulation is based on the solution of the equations of every topological state of the converter, which are solved by an integration method that allows obtaining the time-domain response of the circuit. The algorithm is implemented in a(More)
In this paper, the design and real-time implementation of a compensator (controller-observer) for a nonlinear two-tank liquid level system, linearized at a specific operating point, is presented. The controller uses feedback of this estimated state by means of a Luenberger observer which, in turn, is used to generate a residual signal by comparing the(More)
This paper presents a real-time simulation of a closed loop DC-DC converter implemented in a FPGA platform and programmed with LabVIEW. This implementation allows to generate a user friendly interface that facilitates the analysis and design of control techniques. As a particular case study a Buck converter is simulated with a PI digital controller to keep(More)
In this paper the analysis, design and simulation of a Takagi-Sugeno model for DC-DC converters, the buck-boost as a particular case study, are presented in order to analyze their performance compared to classical models of this converter. The model used for the Takagi-Sugeno fuzzy representation is the reduced nonlinear model. the Takagi-Sugeno fuzzy model(More)
In this paper the design and simulation of a residual generator based on a Luenberger observer is presented. The residual generator is applied to a DC-DC converter in order to indicate disturbances or failures during the system operation. As a particular case study a Buck converter is analyzed, according to its model characteristics a linear observer is(More)
