Abstract
Switched reluctance motor drives are increasingly used in high-performance motion control applications where smooth torque is one of the main requirements. However, in wind turbines, the presence of the air gap flux harmonics gives rise to undesirable torque pulsation. These torque pulsations cause performance deterioration in high-performance drive applications. Conventional methods for torque linearization and decoupling we used in previous works are briefly reviewed such as non-linear mode with current control by hysteresis based techniques. In this work we introduce fuzzy-logic technique to solve this problem and proof its high efficiency in such applications. Speed control is processed using a PI controller and a solution based on the use of fuzzy adaptive systems is then described.
