Özet
In this study, an intuitionistic Takagi–Sugeno fuzzy controller is designed for the speed control of a direct-current motor, and a simulation study is conducted in the MATLAB/Simulink environment. The speed error and its filtered derivative are used as the input variables of the proposed controller. Filtering the error derivative is intended to reduce the adverse effects of high-frequency components that may occur during the transient response. In the intuitionistic fuzzy controller structure, five fuzzy sets are defined for each input variable, and the corresponding non-membership degrees are obtained using the Sugeno generator approach. The rule base, consisting of 25 rules generated from the two controller inputs, is evaluated using the min t-norm intersection and Mamdani implication methods. The controller output is calculated using the Intuitionistic Weighted Average method, which considers the membership and hesitation degrees of the intuitionistic fuzzy information. In the simulations, the speed behavior of the DC motor is represented by a first-order model, a constant reference speed is applied, and the system is examined over a five-second simulation period. The simulation results show that the motor speed approaches the reference value in a stable manner after the initial transient response. The error and filtered error-derivative signals approach zero over time, while the controller output decreases as the system reaches steady state and converges to a value close to zero. These findings demonstrate that the proposed intuitionistic fuzzy controller can provide stable reference tracking for DC motor speed control.
