Hysteretic non-linearity observer design and robust control for piezoelectric actuators

Hysteretic non-linearity observer design and robust control for piezoelectric actuators

The problem of tracking control for piezoelectric actuator (PEA) is investigated in this article. In consideration of that, the control precision of PEA is being restricted due to the hysteretic effect. For the purpose of improving the tracking performance, two issues are, respectively, taken into a...
