Abstract

We present a Hamiltonian control approach for the stabilization of a rigid body system that is controlled by two torques. The stabilization strategy consists in solving a feasible matching condition in order to derive a feedback controller which forces the closed–loop system to be globally asymptotically stable.

Keywords: Control of rigid body system; nonlinear control; Lyapunov stability.

 

Resumen

Presentamos un enfoque de control Hamiltoniano para la estabilización de un sistema de cuerpo rígido que es controlado por dos torques. La estrategia de control consiste en resolver una condición de acoplamiento conveniente con el fin de derivar un eontrolador de retroalimentaeión que haga al sistema en lazo cerrado global y asintóticamente estable.

Descriptores: Control de un sistema de cuerpo rígido; control no–lineal; estabilidad de Lyapunov.
