Abstract :
The paper describes a robust control method for positioning piezoelectric actuators (ultrasonic motor) to achieve highly precise motion. The model employed to describe the motor is an uncertain second-order linear model. Based on the model, robust control can be designed. Real-time experimental results are provided to verify the effectiveness of the proposed scheme when applied to high precision motion trajectory tracking such as intracytoplasmic sperm injection (ICSI).
