Abstract:In this article, an method is proposed combining optimal control for linear system and disturbances observer to control a 3 degree of freedom (3DoF) robot manipulator. By making the tracking error follow a given stable linear reference model through the observer, an optimal controller LQR will be designed to solve the optimization problem for the reference system, thereby leading to good control quality for the original system. The effectiveness of the method is shown through simulation results performed on Ma… Show more
