文摘
- •
Piezoelectric actuator controller is designed considering the hysteresis effect.
- •
The system is modeled as a linear system with a nonlinearity in the forward path.
- •
The stability of output feedback integral controller is derived.
- •
A maximum gain is established for the integral control.
- •
The analysis is demonstrated experimentally.
