Position Control of USM using Variable Gain PID Control Combined with ABC Type Neural Network

In this research, a novel type of intelligent control method based on Neural Network (NN) combined with Artificial Bee Colony (ABC) algorithm to construct an auto-tuning of variable gain PID control is proposed for the control of Ultrasonic Motor (USM). The proposed method is based on PID control with simple structure and capable to improve the control performance on USM's characteristic changes and nonlinearity of USM. Meanwhile, the proposed method is flexible and robust than the traditional fixed gain type PID control owing to the introduction of NN and ABC algorithms. NN is effective inthe compensationof nonlinearity ofUSM. ABC is attractive in its simplicity in estimation and derivative-free characteristics. Their combination makes the proposed intelligent scheme effective and easy to be applied in various applications. In this paper, the control performance and effectiveness of the proposed method was studied according to simulation results in position control of USM.
