| 英文摘要 |
Piezoelectric Actuators (PEAs) are the key components
in nano-positioning. However, the inherent hysteresis
nonlinearity of PEAs is seriously affected the control precision.
In this paper, an active disturbance rejection controller is
proposed to deal with the tracking control of PEAs. First,
the hysteresis nonlinearity is reformulated as a disturbance
of the closed-loop system. With this idea, a disturbance-based
model is derived from the comprehensive model of PEAs. Then
the so-called extended state observer is introduced to real-time
estimate the hysteresis nonlinearity. With the extended state
observer, the model of hysteresis or its inversion are all no longer
needed. To verify the performance of the proposed method,
some experiments are conducted on a commercial PEA. And
the experiment results show that the proposed controller is an
effective way to deal with the tracking control of PEAs. |
