Abstract :
This paper examines the applicability of simplified adaptive control (SAC) technique to an actual system, that is, position control of a 3-axis robot, and verifies that experimental results illustrate satisfactory control performance. In the algorithm, a feedforward gain is proposed to be inserted in parallel to a reference model as well as to the controlled system in order to decrease steady-state error, and this proposition is theoretically analyzed. In the experiments, control performances are compared between the SAC and a conventional PID control. The comparison shows superiority of the SAC.<>
