Sliding-Mode Control of a Flexure Based Mechanism Using Piezoelectric Actuators

A new approach of sliding mode control is introduced which is based on the time varying slope of the sliding line applied to the system. This slope is derived from the values of

* For example (the analyte concentration is unknown) is measured; the concentration is calculated within the dynamic range of the received response calibration curve...

First an appropriate SMC is designed to have continuous control output and then experimental results for position tracking using DSP and analog application are presented

The solution proposed here combines the sliding mode controller and the disturbance rejection method in order to achieve high accuracy in the actuator trajectory tracking.. For

The method uses sliding mode framework to design both the observer and the controller based on an electromechanical lumped model of the piezoelectric actuator.. Furthermore, using
