Single Joint Control of a Flexible Industrial Manipulator using H∞ Loop Shaping
2012 (English)Report (Other academic)
Control of a flexible joint of an industrial manipulator using H∞ loop shaping design is presented. Two controllers are proposed; 1) H∞ loop shaping using the actuator position, and 2) H∞ loop shaping using the actuator position and the acceleration of end-effector. The two controllers are compared to a standard PID controller where only the actuator position is measured. Using the acceleration of the end-effector improves the nominal performance. The performance of the proposed controllers is not significantly decreased in the case of model error consisting of an increased time delay or a gain error.
