On the Steady State Motions Control Problem for Mechanical Systems with Relay Controllers
Keywords:differential equation with discontinuous right-hand side, stability, mechanical system, steady state motion stabilization
The paper presents the solution to the stabilization problem of steady state motions for a holonomic mechanical system by using relay controllers. This solution is achieved by proving new theorems on the asymptotic stability of the solution to a differential equation with a discontinuous right-hand side. The novelty of the theorems is based on the limiting inclusions construction and the use of semidefinite Lyapunov functions. As an example, the stabilization problem of steady-state motion for a five-link robot manipulator is solved by using relay controller.
