Experiments of Twin-Rotor Helicopter model using Exact Linearization via Dynamic State Feedback.

Analysis of Exact Linearization and Aproximate Feedback Linearization Techniques

This paper presents a study of linear control systems based on exact feedback linearization and approximate feedback linearization. As exact feedback linearization is applied, a linear controller can perform the control objectives. The approximate feedback linearization is required when a nonlinear system presents a noninvolutive property. It uses a Taylor series expansion in order to compute a...

Stabilization of the Unicycle via Dynamic Feedback Linearization

We consider the feedback control problem for a wheeled mobile robot with the kinematics of a unicycle, a typical example of nonholonomic robotic system. It is shown that dynamic feedback linearization can be used to design a simple control law which is valid for trajectory tracking as well as point stabilization tasks. In particular, for both cases exponential convergence with linear transients...

Linearization of discrete-time systems via restricted dynamic feedback

We extend the results in [14] to multi-input systems, and utilize these to obtain necessary and sufficient conditions for the linearization of discrete-time nonlinear systems via restricted dynamic feedback. We observe that for discrete-time nonlinear systems, the bound on the number of delays (or integrators) needed to synthesize the linearizing dynamic feedback differs from the continuous-tim...

Helicopter Adaptive Control with Parameter Estimation Based on Feedback Linearization

This paper presents an adaptive feedback linearization approach to derive helicopter. Ideal feedback linearization is defined for the cases when the system model is known. Adaptive feedback linearization is employed to get asymptotically exact cancellation for the inherent uncertainty in the knowledge of the given parameters of system. The control algorithm is implemented using the feedback lin...
