Abstract:

Hedge Algebra (HA) is an algebraic structure for computing, simulating semantics of language, so it can be considered as the basis of fuzzy logic. Using HA for designing the controller can create an algebraic structure in the form of a functional relationship, which allows to form a large set of linguistic values to describe input and output relationships. HA-based research is a new approach in the calculation of fuzzy controllers, so researchers have had ideas applying it in the field of control. The remarkable success of the HA is based on functional reasoning methods that contain a wide variety of open elements. The user can optionally select different approaches in each step of the method. The paper proposes the Hybrid PI – Hedge Algebraic controller applied for the BLDC motor. The control system includes an inner PI controller loop and an outer hedge algebraic controller loop.

Keywords:

 BLDC motor, DC-Link, PI controller, HA, HAC.
