Fuzzy Control of DC-DC Converters with Input Constraint

Fuzzy Control of DC-DC Converters with Input Constraint

This paper proposes a method for designing fuzzy control of DC-DC converters under actuator saturation. Because linear control design methods do not take into account the nonlinearity of the system, a T-S fuzzy model and a controller design approach is used. The designed control not only handles th...
