Due to interaction forces, which strongly depend on the separation between the AFM tip and the sample profile, the cantilever oscillations may present chaotic behaviors, rising when the separation decreases. The stabilization of such periodic solutions is critical for achieving the correct sample topography. In this work, an LMI-based synthesis technique is proposed for determining the controller which guarantees stability of the cantilever oscillation for a wider range of tip-sample separations, thus eliminating unwanted complex dynamics","PeriodicalId":111199,"journal":{"name":"2004 IEEE International Conference on Robotics and Automation (IEEE Cat.

The signal for feedback switches periodically between the plant state which is available via the communication network and the state of a model of the plant that is used to generate control signal when the plant state is not available from the network. A necessary and sufficient condition and a sufficient condition for the robust exponential stability of the closed loop system are derived in terms of the network dwell time and the system parameters. The results suggest a simple procedure for designing the state feedback controller of the system.
