Butterfly-Shaped Linear Ultrasonic Motor Robust Control Based on Takagi-Sugeno Fuzzy Systems
For one-dimensional platform driven by butterfly-shaped linear ultrasonic motor,the Takagi-Sugeno(T-S)models are approached through sector nonlinearity.Based on the T-S models the system augmented method is used for design of servo positioning control algorithm without steady-state error.By considering the robust H∞,a disturbance rejection controller design for the T-S fuzzy models is presented.The designed control algorithm is realized on an embedded micro-controller.Experiments with different values of the stepper servo positioning were carried out.The experimental results show that the overshoot of the system in a different step value are less than 4%.The experimental comparison of servo positioning control between the no-load and load conditions show that the system maximum overshoot is less than 5%.This indicates that the system is robust.
