Abstract
This paper presents different integral optimization criterions with the following integral performance indices: integral of absolute value of error, integral of squared error, integral of time multiplied by absolute value of error, integral of time multiplied by squared error. These integral performance indices are used in simulations for parameters optimization of variable-structure controllers of a three-axis planar articulated robot arm. Optimization of robot controller parameters is performed by computer simulations both in robot joint space and in robot tool-configuration space and better optimization results are achieved in robot tool-configuration space.
