Sampled-data Controller Design with Application to the Quanser AERO 2-DOF Helicopter
Résumé
This paper investigates the importance of considering the discrete-time nature of embedded controllers for continuous-time dynamical systems, namely the sampled-data control approach. To illustrate such approach, an experimental study is conducted with the Quanser ® AERO platform in its 2-DOF helicopter configuration. New LMI-based conditions are provided for the design of sampled-data controllers for linear systems. These are obtained from the usual Lyapunov-Krasovskii approach and useful bounding techniques. The results are validated in simulation as well as experimentally, with a successful comparison to conventional continuous-time controllers design by Quanser ® , especially when the sampling period is high.
