چکیده

This paper is concerned with the derivative feedback control of a 2-degree-of-freedom (2-DOF) torsional bar with parameter perturbations. The time-delay is introduced into the controller and the maximum allowed time-delay bound is estimated by employing a discretized Lyapunov functional method. It is shown, through a numerical example with simulation results, that suitably introducing time-delay into the controller can indeed improve the performance of the stability of the closed-loop system.

Time-Invariant State Feedback Control Laws for a Special Form of Underactuated Nonlinear Systems Using Linear State Bisection

Linear state bisection is introduced as a new method to find time-invariant state feedback control laws for a special form of underactuated nonlinear systems. The specialty of the systems considered is that every unactuated state should be coupled with at least two directly actuated states. The basic idea is based on bisecting actuated states and using linear combinations with adjustable parame...
