PID Parameter Tuning Method of Reluctance Motor Based on Improved RBF-AHP Algorithm

During the operation of a reluctance motor (RM), the output torque fluctuates periodically. Meanwhile, torque pulsation causes the motor rotor to produce unstable torque during rotation, resulting in noise radiation. This paper proposes the PID parameter tuning method based on an improved RBF-AHP algorithm to solve the above problem. RBF-AHP algorithm is a multi-attribute decision-making algorithm, which combines radial basis function and analytic hierarchy method. The RBF-AHP algorithm uses the results of the RBF model to calculate the weight and the AHP algorithm to take the consistency test, rather than directly using the original judgment matrix. The weight of RBF-AHP is used for total hierarchy ranking, and the final decision result is obtained. To verify the effectiveness of the proposed method, MATLAB/Simulink software is used to simulate the SRM torque control system based on the improved RBF-AHP algorithm, and the system oscillation is effectively reduced.
