N2 - Piezoelectric beam's dynamics are characterized by elastic properties, nonlinearities, uncertain dynamics and unknown disturbances, making it a challenging control problem. In this paper, a method of Active Disturbance Rejection Control (ADRC) for piezoelectric beam control is proposed. Unique to this approach, the complex piezoelectric beam dynamics, known or unknown, linear or nonlinear, and all external disturbances are treated in their totality as an input disturbance, and is subsequently estimated and canceled. Simulation and experimental results in this paper demonstrate the significant advancement of the ADRC as an easier, simpler and better control method that is ready to be deployed in practice.
