Raymundo Cordero, Walter Issamu Suemitsu, João Onofre Pereira Pinto · 2013
This paper describes the integration of a Type-I Internal Model Converter (IMC) with the Takagi-Sugeno Fuzzy (TS) modeling technique of a boost converter, in order to control the output of this DC-DC converter. The IMC used in this work adds an integrator to the TS local models, which allows the tracking of step references, according to the internal control principle. Linear matrix inequalities (LMIs) are used to calculate the local controllers, in order to guarantee an asymptotic stability, robustness against variation in the parameters and set the dynamics of the closed-loop control system. Simulation and experimental results proves that the proposed control technique have a good performance and a negligible steady-state error for step references.
